The "Cisco SSH 1.25 exploit" is a legacy DoS vulnerability affecting early Cisco IOS devices running SSHv1. While no modern Cisco equipment is vulnerable, any remaining legacy devices on operational networks (e.g., industrial control systems) must have SSHv1 disabled or be immediately upgraded. The primary defense today is ensuring ip ssh version 2 is enforced globally.
While there is no single "1.25" exploit currently making headlines, several critical SSH-related vulnerabilities have impacted Cisco infrastructure: cisco ssh 1.25 exploit
