What is CVE-2014-125121?
CVE-2014-125121 is a critical vulnerability in Array Networks vAPV, published on 31 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Array Networks vAPV (version 8.3.2.17) and vxAG (version 9.2.0.34) appliances are affected by a privilege escalation vulnerability caused by a combination of hardcoded SSH credentials (or SSH private key) and insecure permissions on a startup script. The devices ship with a default SSH login or a hardcoded DSA private key, allowing an attacker to authenticate remotely with limited privileges.
Once authenticated, an attacker can overwrite the world-writable /ca/bin/monitor.sh script with arbitrary commands. Since this script is executed with elevated privileges through the backend binary, enabling the debug monitor via backend -c "debug monitor on" triggers execution of the attacker's payload as root. This allows full system compromise.
