For example: ``` <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE foo [ <!ENTITY xxe SYSTEM "file:///etc/passwd"> ]> <rss version="0.92"> ... <item> <title>&xxe;</title> <link>https://jira.xwiki.org/browse/XE-307</link> <project id="10222" key="XE">{RETIRED} XWiki Enterprise</project> <description>&xxe;</description> <environment/> ... ``` ### Patches The vulnerability has been patched in the JIRA Extension v8.6.5. ### Workarounds No easy workaround except to upgrade (which is easy using the XWiki Extension Manager). ### References * https://github.com/xwiki-contrib/jira/commit/98a74c2a516b42689c73b13ecd94e9c1998fa9cb and https://github.com/xwiki-contrib/jira/commit/5049e352d16f8356734de70daf1202301f170ee6 * https://jira.xwiki.org/browse/JIRA-49 ### 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:[email protected])
