# CVE-2014-125121

> 10.0 CRITICAL · 🧪 PoC

## Beschreibung

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.

## Schwachstellen-Klasse

- **CWE-732** — Incorrect Permission Assignment for Critical Resource
  The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
- **CWE-798** — Use of Hard-coded Credentials
  The product contains hard-coded credentials, such as a password or cryptographic key.
