CVE-2014-125121
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedArray 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceArray Networks vAPV and vxAG appliances contain hardcoded SSH credentials or a DSA private key that allow remote attackers to gain initial low-privilege access. The attacker can then overwrite the world-writable /ca/bin/monitor.sh script with arbitrary commands, which executes with root privileges when the debug monitor is enabled via the backend binary using 'backend -c debug monitor on', achieving full system compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the appliance modelRun 'uname -a' or check system documentation to confirm the system is an Array Networks vAPV or vxAG applianceAffected if The system is an Array Networks vAPV or vxAG appliance and is reachable over the network
-
Check for hardcoded SSH credentialsInspect SSH configuration files and look for hardcoded usernames/passwords or DSA private keys in /etc/ssh/, /root/, or application config directoriesAffected if Hardcoded SSH credentials or a DSA private key exists on the appliance that allows unauthorized SSH access
-
Verify monitor.sh permissionsRun 'ls -la /ca/bin/monitor.sh' to check if the file is world-writableAffected if The file /ca/bin/monitor.sh exists and has world-writable permissions (mode 777 or similar)
-
Check debug monitor statusRun 'backend -c debug monitor status' or inspect running processes for the debug monitor featureAffected if The debug monitor feature is enabled on the appliance
The environment is affected if it is an Array Networks vAPV or vxAG appliance that contains the hardcoded SSH credentials or DSA private key, has a world-writable /ca/bin/monitor.sh script, and has the debug monitor feature accessible or enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately restrict SSH access to the appliances via firewall rules or VPN, contact Array Networks for patches or firmware updates that remove hardcoded credentials and fix the insecure script permissions, and disable the debug monitor feature if possible as a compensating control.
