BGP Health Check Scanner

This Ruby script implements a lightweight network scanner for basic health verification of a BGP service. It connects to a target TCP port default 179 and performs a minimal, non-exploitative handshake using simplified BGP OPEN and KEEPALIVE messages based on the protocol structure used by the BI...

UBUNTU-CVE-2026-45416

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, SslClientHelloHandler.decode reads the 24-bit TLS handshake length and, when the ClientHello does not fit in the first record, eagerly allocates...

Chisel has an ACL Bypass via Post-Handshake SSH Channel ExtraData Injection

Summary Authenticated chisel clients can bypass --authfile ACL restrictions and tunnel traffic to arbitrary destinations reachable from the server. The ACL is enforced only during the initial handshake against declared remotes, but never on subsequent SSH channels that carry actual traffic. A...
