NewStart CGSL MAIN 7.02 : openssh Vulnerability (NS-SA-2025-0089)

medium Nessus Plugin ID 238004

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 7.02, has openssh packages installed that are affected by a vulnerability:

 - A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. (CVE-2025-26465)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL openssh packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
