Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
XWiki Platform is a generic wiki platform. Starting in version 3.3-milestone-1 and prior to versions 15.10.9 and 16.3.0, on instances where `Extension Repository Application` is installed, any user can execute any code requiring `programming` rights on the server. This vulnerability has been fixed in XWiki 15.10.9 and 16.3.0. Since `Extension Repository Application` is not mandatory, it can be safely disabled on instances that do not use it as a workaround. It is also possible to manually apply the patches from commit 8659f17d500522bf33595e402391592a35a162e8 to the page `ExtensionCode.ExtensionSheet` and to the page `ExtensionCode.ExtensionAuthorsDisplayer`.

Recommended fix High confidence

Upgrade to XWiki 15.10.9 (for 15.x branch) or XWiki 16.3.0 (for 16.x branch)

  1. Determine the currently installed XWiki version to identify if you are on the 15.x or 16.x branch.
  2. Perform a full backup of the XWiki database and the web application directory (file system).
  3. Plan a maintenance window for the upgrade process.
  4. If running version 15.x, upgrade to version 15.10.9. If running version 16.x, upgrade to version 16.3.0.
  5. After the upgrade is complete, restart the application server and verify that the 'Extension Repository Application' is functioning correctly.
Caveat Review the specific release notes for 15.10.9 and 16.3.0 for any migration steps or configuration changes required.
