Nokia 1830 Global Express (GX) is vulnerable to a CLI ACL Bypass vulnerability where a low-privileged authenticated attacker can bypass the SSH isolation mechanism and gain access to the underlying operating system shell via a custom SSH command. This issue occurs by default in the system and is not the result of misconfiguration.
