No affected components available
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.
