Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Vulnerability in upstream cryptographic libraries allowed MITM attackers to exploit the Terrapin attack (CVE-2023-48795), undermining transport security parameters during connection negotiation. This poses a severe risk of authentication and integrity degradation.

Auth Bypass: TCP port forwarding mechanisms (direct-tcpip and tcpip-forward) were enabled by default, allowing unauthenticated or unauthorized clients to utilize the SSH server as a network pivot to access internal services.
