Overview
org.xwiki.platform:xwiki-platform-oldcore is a generic wiki platform offering runtime services for applications built on top of it.
Affected versions of this package are vulnerable to Incorrect Privilege Assignment. An attacker can execute arbitrary code by embedding malicious scripts in their own user profile, which are then executed with elevated privileges when an admin attempts to disable the account.
PoC
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.
