The PUT /api/v2/users/{user}/password endpoint authorized only ActionUpdatePersonal and did not prevent a user-admin from resetting an owner account's password. It also did not require the current password when an admin reset another user's password.
Note: Exploitation requires the privileged
user-adminrole so practical risk is limited to deployments that grantuser-adminto less trusted operators.
A user-admin could reset any owner's password without knowing it, authenticate as that owner and gain full deployment control, including templates, workspaces, licensing, organization settings and the ability to self-assign the owner role. This was a privilege escalation from user-admin to owner.
The fix prevents non-owner users from resetting the password of an account that holds the owner role.
The fix was backported to all supported release lines:
| Release line | Patched version |
|---|---|
| 2.34 | v2.34.2 |
| 2.33 | v2.33.8 |
| 2.32 | v2.32.7 |
| 2.29 (ESR) | v2.29.17 |
Restrict the user-admin role to trusted administrators until upgrading.
