Apache CloudStack

CloudStack users can add and read comments (annotations) on resources they are authorised to access

CVE-2025-22828 - January 13, 2025

CloudStack users can add and read comments (annotations) on resources they are authorised to access.  Due to an access validation issue that affects Apache CloudStack versions from 4.16.0, users who have access, prior access or knowledge of resource UUIDs can list and add comments (annotations) to such resources.  An attacker with a user-account and access or prior knowledge of resource UUIDs may exploit this issue to read contents of the comments (annotations) or add malicious comments (annotations) to such resources.  This may cause potential loss of confidentiality of CloudStack environments and resources if the comments (annotations) contain any privileged information. However, guessing or brute-forcing resource UUIDs are generally hard to impossible and access to listing or adding comments isn't same as access to CloudStack resources, making this issue of very low severity and general low impact. CloudStack admins may also disallow listAnnotations and addAnnotation API access to non-admin roles in their environment as an interim measure.

Account users in Apache CloudStack by default are

CVE-2024-50386 9.9 - Critical - November 12, 2024

Account users in Apache CloudStack by default are allowed to register templates to be downloaded directly to the primary storage for deploying instances. Due to missing validation checks for KVM-compatible templates in CloudStack 4.0.0 through 4.18.2.4 and 4.19.0.0 through 4.19.1.2, an attacker that can register templates, can use them to deploy malicious instances on KVM-based environments and exploit this to gain access to the host filesystems that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of KVM-based infrastructure managed by CloudStack. Users are recommended to upgrade to Apache CloudStack 4.18.2.5 or 4.19.1.3, or later, which addresses this issue. Additionally, all user-registered KVM-compatible templates can be scanned and checked that they are flat files that should not be using any additional or unnecessary features. For example, operators can run the following command on their file-based primary storage(s) and inspect the output. An empty output for the disk being validated means it has no references to the host filesystems; on the other hand, if the output for the disk being validated is not empty, it might indicate a compromised disk. However, bear in mind that (i) volumes created from templates will have references for the templates at first and (ii) volumes can be consolidated while migrating, losing their references to the templates. Therefore, the command execution for the primary storages can show both false positives and false negatives. for file in $(find /path/to/storage/ -type f -regex [a-f0-9\-]*.*); do echo "Retrieving file [$file] info. If the output is not empty, that might indicate a compromised disk; check it carefully."; qemu-img info -U $file | grep file: ; printf "\n\n"; done For checking the whole template/volume features of each disk, operators can run the following command: for file in $(find /path/to/storage/ -type f -regex [a-f0-9\-]*.*); do echo "Retrieving file [$file] info."; qemu-img info -U $file; printf "\n\n"; done

Improper Input Validation

Users logged into the Apache CloudStack's web interface

CVE-2024-45693 8.8 - High - October 16, 2024

Users logged into the Apache CloudStack's web interface can be tricked to submit malicious CSRF requests due to missing validation of the origin of the requests. This can allow an attacker to gain privileges and access to resources of the authenticated users and may lead to account takeover, disruption, exposure of sensitive data and compromise integrity of the resources owned by the user account that are managed by the platform. This issue affects Apache CloudStack from 4.15.1.0 through 4.18.2.3 and 4.19.0.0 through 4.19.1.1 Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue.

Session Riding

The logout operation in the CloudStack web interface does not expire the user session completely

CVE-2024-45462 7.1 - High - October 16, 2024

The logout operation in the CloudStack web interface does not expire the user session completely which is valid until expiry by time or restart of the backend service. An attacker that has access to a user's browser can use an unexpired session to gain access to resources owned by the logged out user account. This issue affects Apache CloudStack from 4.15.1.0 through 4.18.2.3; and from 4.19.0.0 through 4.19.1.1. Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue.

Insufficient Session Expiration

The CloudStack Quota feature

CVE-2024-45461 6.3 - Medium - October 16, 2024

The CloudStack Quota feature allows cloud administrators to implement a quota or usage limit system for cloud resources, and is disabled by default. In environments where the feature is enabled, due to missing access check enforcements, non-administrative CloudStack user accounts are able to access and modify quota-related configurations and data. This issue affects Apache CloudStack from 4.7.0 through 4.18.2.3; and from 4.19.0.0 through 4.19.1.1, where the Quota feature is enabled. Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue. Alternatively, users that do not use the Quota feature are advised to disabled the plugin by setting the global setting "quota.enable.service" to "false".

AuthZ

CloudStack account-users by default use username and password based authentication for API and UI access

CVE-2024-42062 7.2 - High - August 07, 2024

CloudStack account-users by default use username and password based authentication for API and UI access. Account-users can generate and register randomised API and secret keys and use them for the purpose of API-based automation and integrations. Due to an access permission validation issue that affects Apache CloudStack versions 4.10.0 up to 4.19.1.0, domain admin accounts were found to be able to query all registered account-users API and secret keys in an environment, including that of a root admin. An attacker who has domain admin access can exploit this to gain root admin and other-account privileges and perform malicious operations that can result in compromise of resources integrity and confidentiality, data loss, denial of service and availability of CloudStack managed infrastructure. Users are recommended to upgrade to Apache CloudStack 4.18.2.3 or 4.19.1.1, or later, which addresses this issue. Additionally, all account-user API and secret keys should be regenerated.

AuthZ

In Apache CloudStack 4.19.1.0, a regression in the network listing API

CVE-2024-42222 4.3 - Medium - August 07, 2024

In Apache CloudStack 4.19.1.0, a regression in the network listing API allows unauthorised list access of network details for domain admin and normal user accounts. This vulnerability compromises tenant isolation, potentially leading to unauthorised access to network details, configurations and data. Affected users are advised to upgrade to version 4.19.1.1 to address this issue. Users on older versions of CloudStack considering to upgrade, can skip 4.19.1.0 and upgrade directly to 4.19.1.1.

Information Disclosure

The CloudStack SAML authentication (disabled by default) does not enforce signature check

CVE-2024-41107 8.1 - High - July 19, 2024

The CloudStack SAML authentication (disabled by default) does not enforce signature check. In CloudStack environments where SAML authentication is enabled, an attacker that initiates CloudStack SAML single sign-on authentication can bypass SAML authentication by submitting a spoofed SAML response with no signature and known or guessed username and other user details of a SAML-enabled CloudStack user-account. In such environments, this can result in a complete compromise of the resources owned and/or accessible by a SAML enabled user-account. Affected users are recommended to disable the SAML authentication plugin by setting the "saml2.enabled" global setting to "false", or upgrade to version 4.18.2.2, 4.19.1.0 or later, which addresses this issue.

Authentication Bypass by Spoofing

The CloudStack integration API service

CVE-2024-39864 9.8 - Critical - July 05, 2024

The CloudStack integration API service allows running its unauthenticated API server (usually on port 8096 when configured and enabled via integration.api.port global setting) for internal portal integrations and for testing purposes. By default, the integration API service port is disabled and is considered disabled when integration.api.port is set to 0 or negative. Due to an improper initialisation logic, the integration API service would listen on a random port when its port value is set to 0 (default value). An attacker that can access the CloudStack management network could scan and find the randomised integration API service port and exploit it to perform unauthorised administrative actions and perform remote code execution on CloudStack managed hosts and result in complete compromise of the confidentiality, integrity, and availability of CloudStack managed infrastructure. Users are recommended to restrict the network access on the CloudStack management server hosts to only essential ports. Users are recommended to upgrade to version 4.18.2.1, 4.19.0.2 or later, which addresses this issue.

Code Injection

The CloudStack cluster service runs on unauthenticated port (default 9090)

CVE-2024-38346 9.8 - Critical - July 05, 2024

The CloudStack cluster service runs on unauthenticated port (default 9090) that can be misused to run arbitrary commands on targeted hypervisors and CloudStack management server hosts. Some of these commands were found to have command injection vulnerabilities that can result in arbitrary code execution via agents on the hosts that may run as a privileged user. An attacker that can reach the cluster service on the unauthenticated port (default 9090), can exploit this to perform remote code execution on CloudStack managed hosts and result in complete compromise of the confidentiality, integrity, and availability of CloudStack managed infrastructure. Users are recommended to restrict the network access to the cluster service port (default 9090) on a CloudStack management server host to only its peer CloudStack management server hosts. Users are recommended to upgrade to version 4.18.2.1, 4.19.0.2 or later, which addresses this issue.

Code Injection

By default the CloudStack management server honours the x-forwarded-for HTTP header and logs it as the source IP of an API request

CVE-2024-29006 9.8 - Critical - April 04, 2024

By default the CloudStack management server honours the x-forwarded-for HTTP header and logs it as the source IP of an API request. This could lead to authentication bypass and other operational problems should an attacker decide to spoof their IP address this way. Users are recommended to upgrade to CloudStack version 4.18.1.1 or 4.19.0.1, which fixes this issue.

Authentication Bypass by Spoofing

Apache CloudStack version 4.5.0 and later has a SAML 2.0 authentication Service Provider plugin

CVE-2022-35741 9.8 - Critical - July 18, 2022

Apache CloudStack version 4.5.0 and later has a SAML 2.0 authentication Service Provider plugin which is found to be vulnerable to XML external entity (XXE) injection. This plugin is not enabled by default and the attacker would require that this plugin be enabled to exploit the vulnerability. When the SAML 2.0 plugin is enabled in affected versions of Apache CloudStack could potentially allow the exploitation of XXE vulnerabilities. The SAML 2.0 messages constructed during the authentication flow in Apache CloudStack are XML-based and the XML data is parsed by various standard libraries that are now understood to be vulnerable to XXE injection attacks such as arbitrary file reading, possible denial of service, server-side request forgery (SSRF) on the CloudStack management server.

XXE

Apache CloudStack prior to 4.16.1.0 used insecure random number generation for project invitation tokens

CVE-2022-26779 7.5 - High - March 15, 2022

Apache CloudStack prior to 4.16.1.0 used insecure random number generation for project invitation tokens. If a project invite is created based only on an email address, a random token is generated. An attacker with knowledge of the project ID and the fact that the invite is sent, could generate time deterministic tokens and brute force attempt to use them prior to the legitimate receiver accepting the invite. This feature is not enabled by default, the attacker is required to know or guess the project ID for the invite in addition to the invitation token, and the attacker would need to be an existing authorized user of CloudStack.

PRNG

Apache CloudStack 4.1 to 4.8.1.0 and 4.9.0.0 contain an API call designed to allow a user to register for the developer API

CVE-2016-6813 9.8 - Critical - February 06, 2018

Apache CloudStack 4.1 to 4.8.1.0 and 4.9.0.0 contain an API call designed to allow a user to register for the developer API. If a malicious user is able to determine the ID of another (non-"root") CloudStack user, the malicious user may be able to reset the API keys for the other user, in turn accessing their account and resources.
