XWiki Platform vulnerable to code injection from account through XWiki.SchedulerJobSheet
Impact
It's possible to execute anything with the right of the Scheduler Application sheet page.
To reproduce:
- As a user without script or programming rights, edit your user profile with the object editor and add a new object of type XWiki.SchedulerJobClass (search for "Scheduler")
- In "Job Script", add the following
{{/code}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy} {{/async}} - Click "Save & View"
- If the job information isn't already displayed (you should see "Job Name", "Job Description", etc.), append ?sheet=XWiki.SchedulerJobSheet to the URL.
Patches
This has been patched in XWiki 14.10.3 and 15.0 RC1.
Workarounds
While the fix in the scheduler itself is easy, it relies on the code macro source parameter, which was introduced in 14.10.2 so you have to upgrade to benefit from it.
