Description

Impact

When an admin disables a user account, the user's profile is executed with the admin's rights. This allows a user to place malicious code in the user profile before getting an admin to disable the user account.

To reproduce, as a user without script nor programming rights, edit the about section of your user profile and add {{groovy}}services.logging.getLogger("attacker").error("Hello from Groovy!"){{/groovy}}.
As an admin, go to the user profile and click the "Disable this account" button.
Then, reload the page. If the logs show attacker - Hello from Groovy! then the instance is vulnerable.

Patches

This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0.

Workarounds

We're not aware of any workaround except upgrading.

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.
