Detailed vulnerability description
The vulnerability allows a remote unauthenticated attacker to bypass security restrictions on the target system.
The weakness exists in the per-user-override feature due to errors when the affected software constructs and applies per-user-override rules. A remote attacker can connect to a network through an affected device that has a vulnerable configuration and access resources that are behind the affected device and would typically be protected by the interface ACL.
