Ssh20cisco125 Vulnerability Exclusive < Top-Rated • 2025 >

The vulnerability is triggered exclusively by a prime modulus ending in the hex sequence 0x7D (125 decimal) within the first 512 bits of the group prime. Attackers exploit this residual to overflow a signed integer used for calculating the shared secret length.

One of the most striking findings across the analyzed vulnerabilities is Cisco’s reliance on in certain products (e.g., ASA, IOS, IOS XE). The authentication bypass vulnerability (CVE-2026-20009) specifically targets Cisco’s proprietary SSH stack, confirming that Cisco’s homegrown code contains flaws that are not present in mainstream SSH implementations like OpenSSH.

The most probable candidate for a high-impact SSH vulnerability is the critical remote code execution (RCE) flaw disclosed on , affecting the Erlang/OTP SSH server. This vulnerability carries a maximum CVSS v3.1 score of 10.0 and allows an unauthenticated, remote attacker to execute arbitrary code on affected Cisco devices.

While some reports suggest newer Cisco IOS-XR and Meraki products may not be directly impacted, legacy or unpatched Cisco IOS XE devices are considered high-risk targets. Mitigation and Fixes The vulnerability is triggered exclusively by a prime

The SSH20Cisco125 vulnerability is a critical security threat that requires immediate attention. By understanding the vulnerability, its impact, and taking steps to mitigate it, you can help protect your network from potential exploitation. Stay vigilant, and stay informed to ensure the security of your network.

The keyword ssh20cisco125 appears to follow a specific internal naming convention used by threat actors and red teams: This vulnerability carries a maximum CVSS v3

: It involves insufficient validation of cryptographic signatures when SSH public-key authentication is enabled.

In SSH20CISCO125, the attacker sends an with a length field that contradicts the actual payload size. Specifically, the min and preferred group size values are flipped, causing the Cisco SSH daemon (which runs as IOSd process or linux_iosd-image ) to dereference a null pointer in the ssh_kex_compute_hash function. This results in a remote memory leak , exposing portions of the device’s running configuration.
