Array Networks vAPV and vxAG Default Credential Privilege Escalation

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.

A command injection vulnerability was discovered in Array Networks APV products. A remote attacker can send a crafted packet after logging into the affected appliance as an administrator, resulting in arbitrary shell code execution. This is fixed in 8.6.1.262 or newer and 10.4.2.93 or newer.
