SSH-2.0-Cisco-1.25

The identifier is not a specific vulnerability itself, but rather the SSH banner string that many Cisco IOS and IOS XE devices use to identify their software version during an SSH handshake. When vulnerability scanners flag this string, they are typically reporting that the device is susceptible to a broader protocol-level flaw, most commonly the Terrapin Attack (CVE-2023-48795). What is the SSH-2.0-Cisco-1.25 "Vulnerability"?

In a penetration test or real attack, glimpsing SSH-2.0-Cisco-1.25 is gold. Here is how an attacker would proceed: In a penetration test or real attack, glimpsing SSH-2

Look for SSH-2.0-Cisco-1.25 and then check supported KEX/algorithms. Older banners often still allow diffie-hellman-group1-sha1 (weak). ssh-2.0-cisco-1.25 vulnerability

Remote Code Execution (CVE-2025-32433):

Recent reports have identified a critical vulnerability (CVSS 10.0) in certain Cisco products using the Erlang/OTP SSH implementation. It allows unauthenticated remote code execution by sending connection protocol messages before authentication occurs.
