Remote code execution in xwiki-platform

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.
