Ssh20cisco125 Vulnerability

The SSH-2-Cisco-125 vulnerability is a type of buffer overflow vulnerability that occurs in the SSHv2 server implementation on certain Cisco devices. The vulnerability is caused by a lack of proper bounds checking on the input data, which allows an attacker to send a specially crafted SSHv2 packet that overflows the buffer and potentially execute arbitrary code on the device.

The vulnerability existed in several Erlang/OTP SSH server versions across many products. The primary affected versions included: ssh20cisco125 vulnerability

The vulnerability footprint typically points to three distinct architectural failure points within target network hardware: The SSH-2-Cisco-125 vulnerability is a type of buffer

The vulnerability occurs when an attacker sends a specially crafted SSH packet to a vulnerable device, which can cause the device to reload or potentially allow the attacker to execute arbitrary code. This could lead to a range of malicious activities, including unauthorized access to sensitive data, disruption of network services, or even a complete takeover of the device. Specifically, it involves improper validation of the SSH

The vulnerability arises from a flaw in how the Erlang/OTP SSH server handles SSH messages during the authentication phase. Specifically, it involves improper validation of the SSH protocol sequence.
