Date: 2022-02

Attack vector: rce
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2022-23616
CWE: CWE-74
CVSS: 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

### Impact It's possible for an unprivileged user to perform a remote code execution by injecting a groovy script in her own profile and by calling the Reset password feature since the feature is performing a save of the user profile with programming rights in the impacted versions of XWiki. ### Patches The problem has been patched in XWiki 13.1RC1 with a complete refactoring of the Reset password feature. ### Workarounds There's different possible workarounds, all consisting in modifying the XWiki/ResetPassword page. - the Reset password feature can be entirely disabled by deleting the XWiki/ResetPassword page - the script in XWiki/ResetPassword can also be modified or removed: an administrator can replace it with a simple email contact to ask an administrator to reset the password. ### References https://jira.xwiki.org/browse/XWIKI-16661 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](https://jira.xwiki.org) * Email us at [Security mailing-list](mailto:security@xwiki.org)
