CVE-2023-26475
xwiki-platform vulnerable to Remote Code Execution in Annotations
Description
### Impact The annotation displayer does not execute the content in a restricted context. This allows executing anything with the right of the author of any document by annotating the document. To reproduce: add an annotation with the content `{{groovy}}print "hello"{{/groovy}}` and click the yellow scare to get a display of the annotation inline. The result is "hello" but it should be an error suggesting that it's not allowed to use the groovy macro. ### Patches This has been patched in XWiki 13.10.11, 14.4.7 and 14.10. ### Workarounds There is no easy workaround except to upgrade. ### References https://jira.xwiki.org/browse/XWIKI-20360 https://jira.xwiki.org/browse/XWIKI-20384 ### 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) ### Attribution This vulnerability has been reported by René de Sain @renniepak.
