Assumption Retired "The management console is protected by the network perimeter." All three vulnerabilities target administrative interfaces that enterprises assume are internal. Attackers do not need credentials. They need the interface to be reachable.

Insight Pre-authentication exploitation is now the dominant pattern in enterprise appliance compromise. Authentication is not a gate. It is a layer that attackers bypass by targeting what comes before it.

Unresolved Edge When the patch does not exist (Cisco CVE-2025-20393 remains unpatched as of disclosure), the only remediation is to remove the interface from the internet. Most organizations cannot answer how many management interfaces are currently exposed.
