Ssh-2.0-cisco-1.25 Vulnerability !exclusive! -
The underlying SSH server implementation might use deprecated cryptographic algorithms or weak key exchange methods (e.g., Diffie-Hellman Group1).
Legacy SSH implementations were designed in an era when cryptography standards were different. cisco-1.25 often supports:
Additional compatibility problems have been noted with the libssh library and Python's paramiko module, where authentication attempts frequently fail when targeting devices presenting this banner.
Providing the hardware type can help narrow down the exact patch you need. ssh-2.0-cisco-1.25 vulnerability
Academic and industry scans have consistently detected the SSH-2.0-Cisco-1.25 banner in significant numbers globally. The real-world viability of these vulnerabilities is supported by the fact that some of the associated CVEs (particularly CVE-2015-0721) have exploit modules available in frameworks like , showing that exploitation is not just theoretical.
SSH0: Exchanging versions - SSH-2.0-Cisco-1.25 SSH0: send SSH message: outdated is NULL server version string: SSH-2.0-Cisco-1.25
Organizations running devices that broadcast the SSH-2.0-Cisco-1.25 identifier must immediately implement a multi-layered remediation framework to shield infrastructure from exploitation. Step 1: Restrict Management Access with Infrastructure ACLs Providing the hardware type can help narrow down
| Risk Factor | Rating | Justification | | :--- | :--- | :--- | | | High | Weak encryption allows traffic decryption via MitM attacks. | | Integrity | High | Weak key exchange algorithms allow data manipulation. | | Availability | Medium | Potential for DoS via handshake exploitation. | | Attack Complexity | Medium | Requires access to the network path (MitM) or valid credentials (downgrade attacks). |
