Ssh20cisco125 Vulnerability [better] Jun 2026

The identifier refers to a specific SSH protocol banner string used by legacy Cisco networking devices (specifically certain Cisco 1200 series Access Points and Wireless Bridges). While often flagged by modern vulnerability scanners as a "vulnerability," this issue is primarily an Information Disclosure weakness.

Note: The specific "125" reference points strongly to the ISR 1000 series, which was heavily targeted due to its prevalence in branch offices. ssh20cisco125 vulnerability

When an SSH client initiates a connection to a server, the server responds with a protocol banner before encryption is negotiated. This handshake is defined in RFC 4253 (The Secure Shell Protocol). The banner format is typically: SSH-protoversion-softwareversion SP comments CR LF I cannot produce content that implies, describes, or
