XWiki Platform is a generic wiki platform. Starting in version 3.1 and prior to versions 4.10.19, 15.5.4, and 15.10-rc-1, by creating a document with a special crafted documented reference and an `XWiki.SchedulerJobClass` XObject, it is possible to execute arbitrary code on the server whenever an admin visits the scheduler page or the scheduler page is referenced, e.g., via an image in a comment on a page in the wiki. The vulnerability has been fixed in XWiki 14.10.19, 15.5.5, and 15.9. As a workaround, apply the patch manually by modifying the `Scheduler.WebHome` page.

GHSA-37m4-hqxv-w26g — XWiki Platform CSRF remote code execution through scheduler job's document reference

Affected: Maven: org.xwiki.platform:xwiki-platform-scheduler-ui

### Impact By creating a document with a special crafted documented reference and an `XWiki.SchedulerJobClass` XObject, it is possible to execute arbitrary code on the server whenever an admin visits the scheduler page or the scheduler page is referenced, e.g., via an image in a comment on a page in the wiki.

To reproduce on an XWiki installation, click on this link to create a new document : `<xwiki-host>/xwiki/bin/view/%22%3E%5D%5D%7B%7B%2Fhtml%7D%7D%7B%7Basync%20context%3D%22request/parameters%22%7D%7D%7B%7Bvelocity%7D%7D%23evaluate%28%24request/eval%29/`. Then, add to this document an object of type `XWiki.SchedulerJobClass`. Finally, as an admin, go to `<xwiki-host>/xwiki/bin/view/Scheduler/?eval=$services.logging.getLogger(%22attacker%22).error(%22Hello%20from%20URL%20Parameter!%20I%20got%20programming:%20$services.security.authorization.hasAccess(%27programming%27)%22)`. If the logs contain `ERROR attacker - Hello from URL Parameter! I got programming: true`, the installation is vulnerable.

### Patches The vulnerability has been fixed on XWiki 14.10.19, 15.5.5, and 15.9.

### Workarounds Modify the Scheduler.WebHome page following this [patch](https://github.com/xwiki/xwiki-platform/commit/f16ca4ef1513f84ce2e685d4a05d689bd3a2ab4c#diff-1e2995eacccbbbdcc4987ff64f46ac74837d166cf9e92920b4a4f8af0f10bd47).
