A critical unauthenticated remote code execution (RCE) vulnerability was discovered in the OpenSSH server ( sshd ). Because many Cisco products and cloud services integrate OpenSSH, they may be vulnerable if they use glibc-based Linux systems.

There is no widely recognized security vulnerability specifically named "Cisco SSH 1.25 exploit" in official databases or Cisco security advisories . This term may be a misunderstanding or a specific reference to a version of a third-party exploit script rather than a standard Cisco software version. However, several critical SSH-related vulnerabilities have impacted Cisco products in recent years that you may be looking for: Recent High-Impact Cisco SSH Vulnerabilities Erlang/OTP SSH RCE (2025) Because many Cisco products and cloud services integrate

The vulnerability was discovered by researchers at Core Security Technologies, who reported it to Cisco on April 7, 2006. The vulnerability was caused by a buffer overflow in the SSH server's handling of keyboard-interactive authentication. Specifically, the SSH server did not properly validate user input, allowing an attacker to overflow a buffer and execute arbitrary code.
