CVE-2023-29524: Code injection from account through XWiki.SchedulerJobSheet in xwiki-platform
First published: Tue Apr 18 2023(Updated: )
### Impact It's possible to execute anything with the right of the Scheduler Application sheet page. To reproduce: 1. 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") 1. In "Job Script", add the following ```{{/code}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello " + "from groovy!"){{/groovy} {{/async}}``` 1. Click "Save & View" 1. 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. ### References https://jira.xwiki.org/browse/XWIKI-20295 https://jira.xwiki.org/browse/XWIKI-20462 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:security@xwiki.org)
