Name of the Vulnerable Software and Affected Versions XWiki versions prior to 16.10.17 XWiki versions prior to 17.4.9 XWiki versions prior to 17.10.3 XWiki versions prior to 18.1.0-rc-1
Description XWiki Platform allows unauthenticated access to read arbitrary server-side configuration files, such as WEB-INF/xwiki.cfg. This is possible through a Path Traversal issue, where an attacker can use leading slashes in the resource parameter to escape the intended directory. The issue is specifically exploitable via the /bin/ssx/ and /bin/jsx/ endpoints and has been confirmed on Tomcat deployments.
Recommendations Update to version 16.10.17 Update to version 17.4.9 Update to version 17.10.3 Update to version 18.1.0-rc-1
