Remote code execution in xwiki-platform

High severity GitHub Reviewed Published Feb 9, 2022 in xwiki/xwiki-platform • Updated Jan 27, 2023

Package

maven org.xwiki.platform:xwiki-platform-administration-ui (Maven)

Affected versions

>= 3.1-milestone-1, <= 13.0

Patched versions

13.1RC1

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
