CVE-2024-55879Public exploitNetwork attack vector

Script-rights remote code execution via heading evaluation

Published Dec 12, 2024 · Updated Dec 13, 2024

Code injection in XWiki Platform releases before 15.10.9 or 16.3.0 allows remote authenticated users to execute code on the server. XWiki.AdminSheet applies Velocity evaluation to the user-controlled heading of an XWiki.ConfigurableClass object while rendering a configurable section, permitting nested asynchronous Groovy markup to run. Exploitation requires script rights, creation of the object on a page, and viewing the crafted section; successful code execution can read, alter, or interrupt the entire installation.
