BIG-IP iControl REST vulnerability

CVE-2023-42768

What is CVE-2023-42768?

A security vulnerability exists within F5's BIG-IP product where non-admin users who have been mistakenly assigned administrator roles can maintain access to privileged iControl REST resources. This situation arises when the user’s role is reverted to non-admin through various methods including the Configuration utility, tmsh, or iControl REST, but the access rights erroneously persist. This loophole poses a significant risk of unauthorized access, allowing lower-privileged users to exploit elevated rights if their roles are not properly restricted.
