RCE via URL param in XWiki.ConfigurableClass (v2.3-<14.10.15)
CVE-2023-50722 Published on December 15, 2023
XWiki Platform XSS/CSRF Remote Code Execution in XWiki.ConfigurableClass
XWiki Platform is a generic wiki platform. Starting in 2.3 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, there is a reflected XSS or also direct remote code execution vulnerability in the code for displaying configurable admin sections. The code that can be passed through a URL parameter is only executed when the user who is visiting the crafted URL has edit right on at least one configuration section. While any user of the wiki could easily create such a section, this vulnerability doesn't require the attacker to have an account or any access on the wiki. It is sufficient to trick any admin user of the XWiki installation to visit the crafted URL. This vulnerability allows full remote code execution with programming rights and thus impacts the confidentiality, integrity and availability of the whole XWiki installation. This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1. The patch can be manually applied to the document `XWiki.ConfigurableClass`.

Weakness Types
What is a XSS Vulnerability?
The software does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
CVE-2023-50722 has been classified to as a XSS vulnerability or weakness.
What is a Session Riding Vulnerability?
The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. When a web server is designed to receive a request from a client without any mechanism for verifying that it was intentionally sent, then it might be possible for an attacker to trick a client into making an unintentional request to the web server which will be treated as an authentic request. This can be done via a URL, image load, XMLHttpRequest, etc. and can result in exposure of data or unintended code execution.
CVE-2023-50722 has been classified to as a Session Riding vulnerability or weakness.
