: Remote, authenticated. An attacker with low-privileged access can trigger the vulnerability by creating an SSH connection and sending a specific sequence of packets. Impact
Although the ssh20cisco125 vulnerabilities were patched nearly two decades ago, they remain relevant for several reasons:
Cisco has confirmed impact on products including ConfD , Network Services Orchestrator (NSO) , and Ultra Cloud Core . ssh20cisco125 vulnerability
Specifically targets Engineering Special (ES) versions of Unified CM 15.0.1. Standard versions, including 12.5 , are reported as not affected by this specific hard-coded credential flaw.
The attacker sends an SSH message sequence that is unexpected during the pre-authentication phase. : Remote, authenticated
The phrase is a highly specific signature string frequently encountered during network security assessments, automated vulnerability scanning, and penetration testing. It relates directly to a historical or custom-flagged vulnerability signature indicating an exposed, misconfigured, or unpatched Cisco Secure Shell (SSH) version 2.0 implementation or specific device software versions.
The ssh-20-cisco-125 vulnerability is caused by a weakness in the way Cisco devices handle SSH connections. Specifically, the vulnerability occurs when an attacker sends a specially crafted SSH packet to a Cisco device, which can cause a buffer overflow condition. This buffer overflow can allow an attacker to execute arbitrary code on the device, potentially leading to a complete compromise of the device. The phrase is a highly specific signature string
A critical vulnerability (CVSS 10.0) discovered in the Erlang/OTP SSH library used by many Cisco devices.
: Use the Cisco Software Checker to verify if your specific IOS/IOS XE release is vulnerable and to find the earliest "First Fixed" release.
Feel free to modify it according to your requirement. Also, I'll be happy to assist you in polishing it further if required.
An attacker must have valid administrative credentials. Crucially, even read-only accounts can exploit this flaw.
