In short
A web interface flaw in CP-8031 and CP-8050 devices allows an authenticated administrator to run malicious commands with full system access by sending specially crafted input. This gives attackers complete control over the affected device.
Technical detail
The web interface fails to sanitize user input on the server side, enabling command injection attacks. An authenticated attacker with administrative privileges can inject arbitrary OS commands that execute with root-level access, leading to complete system compromise.
