CVE-2024-55876 Information

Description

XWiki Platform is a generic wiki platform. Starting in version 1.2-milestone-2 and prior to versions 15.10.9 and 16.3.0 any user with an account on the main wiki could run scheduling operations on subwikis. To reproduce as a user on the main wiki without any special right view the document Scheduler.WebHome in a subwiki. Then click on any operation (e.g. Trigger) on any job. If the operation is successful then the instance is vulnerable. This has been patched in XWiki 15.10.9 and 16.3.0. As a workaround those who have subwikis where the Job Scheduler is enabled can edit the objects on Scheduler.WebPreferences to match the patch.
