NewStart CGSL MAIN 7.02 : openssh Multiple Vulnerabilities (NS-SA-2026-0101)

critical Nessus Plugin ID 343592

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

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

- ssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re- exchange. (This outcome occurs only on the client side.) (CVE-2026-60002)

- In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without
-p (preserve mode). (CVE-2026-35385)

- In OpenSSH before 10.3, command execution can occur via shell metacharacters in a username within a command line. This requires a scenario where the username on the command line is untrusted, and also requires a non-default configurations of % in ssh_config. (CVE-2026-35386)

- OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms.
(CVE-2026-35387)

- OpenSSH before 10.3 omits connection multiplexing confirmation for proxy-mode multiplexing sessions.
(CVE-2026-35388)

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.
