The XWiki Admin Tools Application provides tools to help the administration of XWiki

CVE-2023-48293 8.8 - High - November 20, 2023

The XWiki Admin Tools Application provides tools to help the administration of XWiki. Prior to version 4.5.1, a cross-site request forgery vulnerability in the query on XWiki tool allows executing arbitrary database queries on the database of the XWiki installation. Among other things, this allows modifying and deleting all data of the wiki. This could be both used to damage the wiki and to create an account with elevated privileges for the attacker, thus impacting the confidentiality, integrity and availability of the whole XWiki instance. A possible attack vector are comments on the wiki, by embedding an image with wiki syntax like `[[image:path:/xwiki/bin/view/Admin/QueryOnXWiki?query=DELETE%20FROM%20xwikidoc]]`, all documents would be deleted from the database when an admin user views this comment. This has been patched in Admin Tools Application 4.5.1 by adding form token checks. Some workarounds are available. The patch can also be applied manually to the affected pages. Alternatively, if the query tool is not needed, by deleting the document `Admin.SQLToolsGroovy`, all database query tools can be deactivated.

XWiki Platform is a generic wiki platform

CVE-2023-48241 7.5 - High - November 20, 2023

XWiki Platform is a generic wiki platform. Starting in version 6.3-milestone-2 and prior to versions 14.10.15, 15.5.1, and 15.6RC1, the Solr-based search suggestion provider that also duplicates as generic JavaScript API for search results in XWiki exposes the content of all documents of all wikis to anybody who has access to it, by default it is public. This exposes all information stored in the wiki (but not some protected information like password hashes). While there is a right check normally, the right check can be circumvented by explicitly requesting fields from Solr that don't include the data for the right check. This has been fixed in XWiki 15.6RC1, 15.5.1 and 14.10.15 by not listing documents whose rights cannot be checked. No known workarounds are available.

XWiki Platform is a generic wiki platform

CVE-2023-48240 8.8 - High - November 20, 2023

XWiki Platform is a generic wiki platform. The rendered diff in XWiki embeds images to be able to compare the contents and not display a difference for an actually unchanged image. For this, XWiki requests all embedded images on the server side. These requests are also sent for images from other domains and include all cookies that were sent in the original request to ensure that images with restricted view right can be compared. Starting in version 11.10.1 and prior to versions 14.10.15, 15.5.1, and 15.6, this allows an attacker to steal login and session cookies that allow impersonating the current user who views the diff. The attack can be triggered with an image that references the rendered diff, thus making it easy to trigger. Apart from stealing login cookies, this also allows server-side request forgery (the result of any successful request is returned in the image's source) and viewing protected content as once a resource is cached, it is returned for all users. As only successful requests are cached, the cache will be filled by the first user who is allowed to access the resource. This has been patched in XWiki 14.10.15, 15.5.1 and 15.6. The rendered diff now only downloads images from trusted domains. Further, cookies are only sent when the image's domain is the same the requested domain. The cache has been changed to be specific for each user. As a workaround, the image embedding feature can be disabled by deleting `xwiki-platform-diff-xml-<version>.jar` in `WEB-INF/lib/`.

CVE-2023-46244 8.8 - High - November 07, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions it's possible for a user to write a script in which any velocity content is executed with the right of any other document content author. Since this API require programming right and the user does not have it, the expected result is `$doc.document.authors.contentAuthor` (not executed script), unfortunately with the security vulnerability it is possible for the attacker to get `XWiki.superadmin` which shows that the title was executed with the right of the unmodified document. This has been patched in XWiki versions 14.10.7 and 15.2RC1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2023-46732 6.1 - Medium - November 06, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki is vulnerable to reflected cross-site scripting (RXSS) via the `rev` parameter that is used in the content of the content menu without escaping. If an attacker can convince a user to visit a link with a crafted parameter, this allows the attacker to execute arbitrary actions in the name of the user, including remote code (Groovy) execution in the case of a user with programming right, compromising the confidentiality, integrity and availability of the whole XWiki installation. This has been patched in XWiki 15.6 RC1, 15.5.1 and 14.10.14. The patch in commit `04e325d57` can be manually applied without upgrading (or restarting) the instance. Users are advised to upgrade or to manually apply the patch. There are no known workarounds for this vulnerability.

XSS

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-46731 9.8 - Critical - November 06, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki doesn't properly escape the section URL parameter that is used in the code for displaying administration sections. This allows any user with read access to the document `XWiki.AdminSheet` (by default, everyone including unauthenticated users) to execute code including Groovy code. This impacts the confidentiality, integrity and availability of the whole XWiki instance. This vulnerability has been patched in XWiki 14.10.14, 15.6 RC1 and 15.5.1. Users are advised to upgrade. Users unablr to upgrade may apply the fix in commit `fec8e0e53f9` manually. Alternatively, to protect against attacks from unauthenticated users, view right for guests can be removed from this document (it is only needed for space and wiki admins).

Code Injection

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-45137 5.4 - Medium - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. `org.xwiki.platform:xwiki-platform-web` starting in version 3.1-milestone-2 and prior to version 13.4-rc-1, as well as `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.12 and 15.5-rc-1, are vulnerable to cross-site scripting. When trying to create a document that already exists, XWiki displays an error message in the form for creating it. Due to missing escaping, this error message is vulnerable to raw HTML injection and thus XSS. The injected code is the document reference of the existing document so this requires that the attacker first creates a non-empty document whose name contains the attack code. This has been patched in `org.xwiki.platform:xwiki-platform-web` version 13.4-rc-1 and `org.xwiki.platform:xwiki-platform-web-templates` versions 14.10.12 and 15.5-rc-1 by adding the appropriate escaping. The vulnerable template file `createinline.vm` is part of XWiki's WAR and can be patched by manually applying the changes from the fix.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-45136 9.6 - Critical - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When document names are validated according to a name strategy (disabled by default), XWiki starting in version 12.0-rc-1 and prior to versions 12.10.12 and 15.5-rc-1 is vulnerable to a reflected cross-site scripting attack in the page creation form. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in XWiki 14.10.12 and 15.5-rc-1 by adding appropriate escaping. The vulnerable template file `createinline.vm` is part of XWiki's WAR and can be patched by manually applying the changes from the fix.

XSS

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-45135 8 - High - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In `org.xwiki.platform:xwiki-platform-web` versions 7.2-milestone-2 until 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.12 and 15.5-rc-1, it is possible to pass a title to the page creation action that isn't displayed at first but then executed in the second step. This can be used by an attacker to trick a victim to execute code, allowing script execution if the victim has script right or remote code execution including full access to the XWiki instance if the victim has programming right. For the attack to work, the attacker needs to convince the victim to visit a link like `<xwiki-host>/xwiki/bin/create/NonExistingSpace/WebHome?title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)` where `<xwiki-host>` is the URL of the Wiki installation and to then click on the "Create" button on that page. The page looks like a regular XWiki page that the victim would also see when clicking the button to create a page that doesn't exist yet, the malicious code is not displayed anywhere on that page. After clicking the "Create" button, the malicious title would be displayed but at this point, the code has already been executed and the attacker could use this code also to hide the attack, e.g., by redirecting the victim again to the same page with an innocent title. It thus seems plausible that this attack could work if the attacker can place a fake "create page" button on a page which is possible with edit right. This has been patched in `org.xwiki.platform:xwiki-platform-web` version 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` versions 14.10.12 and 15.5-rc-1 by displaying the title already in the first step such that the victim can notice the attack before continuing. It is possible to manually patch the modified files from the patch in an existing installation. For the JavaScript change, the minified JavaScript file would need to be obtained from a build of XWiki and replaced accordingly.

Output Sanitization

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-45134 9 - Critical - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. `org.xwiki.platform:xwiki-platform-web` starting in version 3.1-milestone-1 and prior to 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` starting in version 2.4-milestone-2 and prior to version 3.1-milestone-1 are vulnerable to cross-site scripting. An attacker can create a template provider on any document that is part of the wiki (could be the attacker's user profile) that contains malicious code. This code is executed when this template provider is selected during document creation which can be triggered by sending the user to a URL. For the attacker, the only requirement is to have an account as by default the own user profile is editable. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in `org.xwiki.platform:xwiki-platform-web` 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` 3.1-milestone-1 by adding the appropriate escaping. The vulnerable template file createinline.vm is part of XWiki's WAR and can be patched by manually applying the changes from the fix.

XSS

XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another syntax

CVE-2023-37908 9.6 - Critical - October 25, 2023

XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another syntax. The cleaning of attributes during XHTML rendering, introduced in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid attribute names. This can be exploited, e.g., via the link syntax in any content that supports XWiki syntax like comments in XWiki. When a user moves the mouse over a malicious link, the malicious JavaScript code is executed in the context of the user session. When this user is a privileged user who has programming rights, this allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. While this attribute was correctly recognized as not allowed, the attribute was still printed with a prefix `data-xwiki-translated-attribute-` without further cleaning or validation. This problem has been patched in XWiki 14.10.4 and 15.0 RC1 by removing characters not allowed in data attributes and then validating the cleaned attribute again. There are no known workarounds apart from upgrading to a version including the fix.

XSS

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-37911 6.5 - Medium - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 9.4-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, when a document has been deleted and re-created, it is possible for users with view right on the re-created document but not on the deleted document to view the contents of the deleted document. Such a situation might arise when rights were added to the deleted document. This can be exploited through the diff feature and, partially, through the REST API by using versions such as `deleted:1` (where the number counts the deletions in the wiki and is thus guessable). Given sufficient rights, the attacker can also re-create the deleted document, thus extending the scope to any deleted document as long as the attacker has edit right in the location of the deleted document. This vulnerability has been patched in XWiki 14.10.8 and 15.3 RC1 by properly checking rights when deleted revisions of a document are accessed. The only workaround is to regularly clean deleted documents to minimize the potential exposure. Extra care should be taken when deleting sensitive documents that are protected individually (and not, e.g., by being placed in a protected space) or deleting a protected space as a whole.

CVE-2023-37910 8.1 - High - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting with the introduction of attachment move support in version 14.0-rc-1 and prior to versions 14.4.8, 14.10.4, and 15.0-rc-1, an attacker with edit access on any document (can be the user profile which is editable by default) can move any attachment of any other document to this attacker-controlled document. This allows the attacker to access and possibly publish any attachment of which the name is known, regardless if the attacker has view or edit rights on the source document of this attachment. Further, the attachment is deleted from the source document. This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1. There is no workaround apart from upgrading to a fixed version.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 5.1-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, any user who can edit their own user profile can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.8 and 15.3-rc-1 by adding proper escaping. As a workaround, the patch can be manually applied to the document `Menu.UIExtensionSheet`; only three lines need to be changed.

Code Injection

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-37913 8.8 - High - October 25, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 3.5-milestone-1 and prior to versions 14.10.8 and 15.3-rc-1, triggering the office converter with a specially crafted file name allows writing the attachment's content to an attacker-controlled location on the server as long as the Java process has write access to that location. In particular in the combination with attachment moving, a feature introduced in XWiki 14.0, this is easy to reproduce but it also possible to reproduce in versions as old as XWiki 3.5 by uploading the attachment through the REST API which doesn't remove `/` or `\` from the filename. As the mime type of the attachment doesn't matter for the exploitation, this could e.g., be used to replace the `jar`-file of an extension which would allow executing arbitrary Java code and thus impact the confidentiality, integrity and availability of the XWiki installation. This vulnerability has been patched in XWiki 14.10.8 and 15.3RC1. There are no known workarounds apart from disabling the office converter.

Directory traversal

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-41046 6.3 - Medium - September 01, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It is possible in XWiki to execute Velocity code without having script right by creating an XClass with a property of type "TextArea" and content type "VelocityCode" or "VelocityWiki". For the former, the syntax of the document needs to be set the `xwiki/1.0` (this syntax doesn't need to be installed). In both cases, when adding the property to an object, the Velocity code is executed regardless of the rights of the author of the property (edit right is still required, though). In both cases, the code is executed with the correct context author so no privileged APIs can be accessed. However, Velocity still grants access to otherwise inaccessible data and APIs that could allow further privilege escalation. At least for "VelocityCode", this behavior is most likely very old but only since XWiki 7.2, script right is a separate right, before that version all users were allowed to execute Velocity and thus this was expected and not a security issue. This has been patched in XWiki 14.10.10 and 15.4 RC1. Users are advised to upgrade. There are no known workarounds.

CVE-2023-40573 8.8 - High - August 24, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki supports scheduled jobs that contain Groovy scripts. Currently, the job checks the content author of the job for programming right. However, modifying or adding a job script to a document doesn't modify the content author. Together with a CSRF vulnerability in the job scheduler, this can be exploited for remote code execution by an attacker with edit right on the wiki. If the attack is successful, an error log entry with "Job content executed" will be produced. This vulnerability has been patched in XWiki 14.10.9 and 15.4RC1.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-40572 8 - High - August 24, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The create action is vulnerable to a CSRF attack, allowing script and thus remote code execution when targeting a user with script/programming right, thus compromising the confidentiality, integrity and availability of the whole XWiki installation. When a user with script right views this image and a log message `ERROR foo - Script executed!` appears in the log, the XWiki installation is vulnerable. This has been patched in XWiki 14.10.9 and 15.4RC1 by requiring a CSRF token for the actual page creation.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-40177 8.8 - High - August 23, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any registered user can use the content field of their user profile page to execute arbitrary scripts with programming rights, thus effectively performing rights escalation. This issue is present since version 4.3M2 when AppWithinMinutes Application added support for the Content field, allowing any wiki page (including the user profile page) to use its content as an AWM Content field, which has a custom displayer that executes the content with the rights of the ``AppWithinMinutes.Content`` author, rather than the rights of the content author. The vulnerability has been fixed in XWiki 14.10.5 and 15.1RC1. The fix is in the content of the AppWithinMinutes.Content page that defines the custom displayer. By using the ``display`` script service to render the content we make sure that the proper author is used for access rights checks.

Code Injection

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-40176 5.4 - Medium - August 23, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any registered user can exploit a stored XSS through their user profile by setting the payload as the value of the time zone user preference. Even though the time zone is selected from a drop down (no free text value) it can still be set from JavaScript (using the browser developer tools) or by calling the save URL on the user profile with the right query string. Once the time zone is set it is displayed without escaping which means the payload gets executed for any user that visits the malicious user profile, allowing the attacker to steal information and even gain more access rights (escalation to programming rights). This issue is present since version 4.1M2 when the time zone user preference was introduced. The issue has been fixed in XWiki 14.10.5 and 15.1RC1.

Users unable to upgrade may manually apply the patch on `Invitation.InvitationCommon` and `Invitation.InvitationConfig`, but there are otherwise no known workarounds for this vulnerability.

Code Injection

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-37462 8.8 - High - July 14, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Improper escaping in the document `SkinsCode.XWikiSkinsSheet` leads to an injection vector from view right on that document to programming rights, or in other words, it is possible to execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The attack works by opening a non-existing page with a name crafted to contain a dangerous payload. It is possible to check if an existing installation is vulnerable. See the linked GHSA for instructions on testing an installation. This issue has been patched in XWiki 14.4.8, 14.10.4 and 15.0-rc-1. Users are advised to upgrade. The fix commit `d9c88ddc` can also be applied manually to the impacted document `SkinsCode.XWikiSkinsSheet` and users unable to upgrade are advised to manually patch their installations.

Injection

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-37277 9.6 - Critical - July 10, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The REST API allows executing all actions via POST requests and accepts `text/plain`, `multipart/form-data` or `application/www-form-urlencoded` as content types which can be sent via regular HTML forms, thus allowing cross-site request forgery. With the interaction of a user with programming rights, this allows remote code execution through script macros and thus impacts the integrity, availability and confidentiality of the whole XWiki installation. For regular cookie-based authentication, the vulnerability is mitigated by SameSite cookie restrictions but as of March 2023, these are not enabled by default in Firefox and Safari. The vulnerability has been patched in XWiki 14.10.8 and 15.2 by requiring a CSRF token header for certain request types that are susceptible to CSRF attacks.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-36477 5.4 - Medium - June 30, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit rights can edit all pages in the `CKEditor' space. This makes it possible to perform a variety of harmful actions, such as removing technical documents, leading to loss of service and editing the javascript configuration of CKEditor, leading to persistent XSS. This issue has been patched in XWiki 14.10.6 and XWiki 15.1. This issue has been patched on the CKEditor Integration extension 1.64.9 for XWiki version older than 14.6RC1. Users are advised to upgrade. Users unable to upgrade may manually address the issue by restricting the `edit` and `delete` rights to a trusted user or group (e.g. the `XWiki.XWikiAdminGroup` group), implicitly disabling those rights for all other users. See commit `9d9d86179` for details.

XSS

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-36470 8.8 - High - June 29, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. By either creating a new or editing an existing document with an icon set, an attacker can inject XWiki syntax and Velocity code that is executed with programming rights and thus allows remote code execution. There are different attack vectors, the simplest is the Velocity code in the icon set's HTML or XWiki syntax definition. The [icon picker](https://extensions.xwiki.org/xwiki/bin/view/Extension/Icon%20Theme%20Application#HIconPicker) can be used to trigger the rendering of any icon set. The XWiki syntax variant of the icon set is also used without any escaping in some documents, allowing to inject XWiki syntax including script macros into a document that might have programming right, for this the currently used icon theme needs to be edited. Further, the HTML output of the icon set is output as JSON in the icon picker and this JSON is interpreted as XWiki syntax, allowing again the injection of script macros into a document with programming right and thus allowing remote code execution. This impacts the confidentiality, integrity and availability of the whole XWiki instance. This issue has been patched in XWiki 14.10.6 and 15.1. Icon themes now require script right and the code in the icon theme is executed within the context of the icon theme, preventing any rights escalation. A macro for displaying icons has been introduced to avoid injecting the raw wiki syntax of an icon set into another document. Users are advised to upgrade. There are no known workarounds for this vulnerability.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can edit their own user profile and notification settings can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.6 and 15.2RC1. Users are advised to update. As a workaround the main security fix can be manually applied by patching the affected document `XWiki.Notifications.Code.NotificationRSSService`. This will break the link to the differences, though as this requires additional changes to Velocity templates as shown in the patch. While the default template is available in the instance and can be easily patched, the template for mentions is contained in a `.jar`-file and thus cannot be fixed without replacing that jar.

CVE-2023-36468 8.8 - High - June 29, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When an XWiki installation is upgraded and that upgrade contains a fix for a bug in a document, just a new version of that document is added. In some cases, it's still possible to exploit the vulnerability that was fixed in the new version. The severity of this depends on the fixed vulnerability, for the purpose of this advisory take CVE-2022-36100/GHSA-2g5c-228j-p52x as example - it is easily exploitable with just view rights and critical. When XWiki is upgraded from a version before the fix for it (e.g., 14.3) to a version including the fix (e.g., 14.4), the vulnerability can still be reproduced by adding `rev=1.1` to the URL used in the reproduction steps so remote code execution is possible even after upgrading. Therefore, this affects the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability also affects manually added script macros that contained security vulnerabilities that were later fixed by changing the script macro without deleting the versions with the security vulnerability from the history. This vulnerability doesn't affect freshly installed versions of XWiki. Further, this vulnerability doesn't affect content that is only loaded from the current version of a document like the code of wiki macros or UI extensions. This vulnerability has been patched in XWiki 14.10.7 and 15.2RC1 by forcing old revisions to be executed in a restricted mode that disables all script macros. As a workaround, admins can manually delete old revisions of affected documents. A script could be used to identify all installed documents and delete the history for them. However, also manually added and later corrected code may be affected by this vulnerability so it is easy to miss documents.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can create a space can become admin of that space through App Within Minutes. The admin right implies the script right and thus allows JavaScript injection. The vulnerability can be exploited by creating an app in App Within Minutes. If the button should be disabled because the user doesn't have global edit right, the app can also be created by directly opening `/xwiki/bin/view/AppWithinMinutes/CreateApplication?wizard=true` on the XWiki installation. This has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1 by not granting the space admin right if the user doesn't have script right on the space where the app is created. Error message are displayed to warn the user that the app will be broken in this case. Users who became space admin through this vulnerability won't loose the space admin right due to the fix, so it is advised to check if all users who created AWM apps should keep their space admin rights. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2023-29510 8.8 - High - April 19, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In XWiki, every user can add translations that are only applied to the current user. This also allows overriding existing translations. Such translations are often included in privileged contexts without any escaping which allows remote code execution for any user who has edit access on at least one document which could be the user's own profile where edit access is enabled by default. A mitigation for this vulnerability is part of XWiki 14.10.2 and XWiki 15.0 RC1: translations with user scope now require script right. This means that regular users cannot exploit this anymore as users don't have script right by default anymore starting with XWiki 14.10.

Exposure of Resource to Wrong Sphere

XWiki Commons are technical libraries common to several other top level XWiki projects

CVE-2023-29207 9 - Critical - April 15, 2023

XWiki Commons are technical libraries common to several other top level XWiki projects. The Livetable Macro wasn't properly sanitizing column names, thus allowing the insertion of raw HTML code including JavaScript. This vulnerability was also exploitable via the Documents Macro that is included since XWiki 3.5M1 and doesn't require script rights, this can be demonstrated with the syntax `{{documents id="example" count="5" actions="false" columns="doc.title, before<script>alert(1)</script>after"/}}`. Therefore, this can also be exploited by users without script right and in comments. With the interaction of a user with more rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content. This has been patched in XWiki 14.9, 14.4.6, and 13.10.10.

XSS

CVE-2023-29205 5.4 - Medium - April 15, 2023

XWiki Commons are technical libraries common to several other top level XWiki projects. The HTML macro does not systematically perform a proper neutralization of script-related html tags. As a result, any user able to use the html macro in XWiki, is able to introduce an XSS attack. This can be particularly dangerous since in a standard wiki, any user is able to use the html macro directly in their own user profile page. The problem has been patched in XWiki 14.8RC1. The patch involves the HTML macros and are systematically cleaned up whenever the user does not have the script correct.

XSS

Exposure of Resource to Wrong Sphere

XWiki Commons are technical libraries common to several other top level XWiki projects

CVE-2023-29202 9 - Critical - April 15, 2023

XWiki Commons are technical libraries common to several other top level XWiki projects. The RSS macro that is bundled in XWiki included the content of the feed items without any cleaning in the HTML output when the parameter `content` was set to `true`. This allowed arbitrary HTML and in particular also JavaScript injection and thus cross-site scripting (XSS) by specifying an RSS feed with malicious content. With the interaction of a user with programming rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content and sabotaging the wiki. The issue has been patched in XWiki 14.6 RC1, the content of the feed is now properly cleaned before being displayed. As a workaround, if the RSS macro isn't used in the wiki, the macro can be uninstalled by deleting `WEB-INF/lib/xwiki-platform-rendering-macro-rss-XX.jar`, where `XX` is XWiki's version, in the web application's directory.

XSS

XWiki Commons are technical libraries common to several other top level XWiki projects

CVE-2023-29201 9 - Critical - April 15, 2023

XWiki Commons are technical libraries common to several other top level XWiki projects. The "restricted" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1, only escaped `<script>` and `<style>`-tags but neither attributes that can be used to inject scripts nor other dangerous HTML tags like `<iframe>`. As a consequence, any code relying on this "restricted" mode for security is vulnerable to JavaScript injection ("cross-site scripting"/XSS). When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. This problem has been patched in XWiki 14.6 RC1 with the introduction of a filter with allowed HTML elements and attributes that is enabled in restricted mode. There are no known workarounds apart from upgrading to a version including the fix.

XXE

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it

CVE-2023-27479 9.9 - Critical - March 07, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with view rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of UIX parameters. A proof of concept exploit is to log in, add an `XWiki.UIExtensionClass` xobject to the user profile page, with an Extension Parameters content containing `label={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}`. Then, navigating to `PanelsCode.ApplicationsPanelConfigurationSheet` (i.e., `<xwiki-host>/xwiki/bin/view/PanelsCode/ApplicationsPanelConfigurationSheet` where `<xwiki-host>` is the URL of your XWiki installation) should not execute the Groovy script. If it does, you will see `Hello from groovy!` displayed on the screen. This vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1. Users are advised to upgrade. For users unable to upgrade the issue can be fixed by editing the `PanelsCode.ApplicationsPanelConfigurationSheet` wiki page and making the same modifications as shown in commit `6de5442f3c`.
