Ssh-2.0-cisco-1.25 Vulnerability 〈Android〉

: In situations like CVE-2020-3200, an internal state within the SSH state machine is handled incorrectly during an active connection.

Understanding the SSH-2.0-Cisco-1.25 Vulnerability: Risks, Identification, and Mitigation

Because the banner string cannot simply be hidden or toggled off manually within native Cisco software commands, administrators must secure the underlying service. Step 1: Verify the Device OS via Cisco Software Checker ssh-2.0-cisco-1.25 vulnerability

This string indicates that the device is running a specific, often older or unpatched, version of the Cisco SSH server implementation. While appearing as "SSH-2.0", which suggests the standard Secure Shell Protocol version 2, the implementation details within 1.25 often correspond to older Cisco IOS or Cisco IOS-XE releases. Why is it Flagged as a Vulnerability?

The age of the underlying cryptographic stack associated with the 1.25 banner creates a third category of risk. A banner from this era likely supports outdated, weaker algorithms that are no longer considered secure.

Weak algorithms could allow for the decryption of session data. While appearing as "SSH-2

:

If successful, the attacker can log in with the privileges of that user (often administrative). B. Denial of Service (DoS) - Unexpected Reload

Resolving the risks associated with this banner requires a multi-layered security approach. Step 1: Upgrade Cisco IOS/IOS-XE

used by many modern Cisco products. It allows unauthenticated attackers to execute arbitrary code by sending specific messages before authentication occurs. Würth Phoenix Terrapin Attack (CVE-2023-48795)
