CyberRota Analysis
AI-GeneratedMultiple Zbtlink and other firmware versions are vulnerable to an unauthenticated command injection in the infosrvd service, allowing remote attackers to execute arbitrary commands with root privileges via crafted UDP packets. The exploitation is facilitated by ineffective authentication mechanisms, including a hardcoded salt and a wildcard MAC bypass. Organizations using these affected devices should prioritize immediate patching or mitigation efforts to prevent potential unauthorized access and system compromise.
Original NVD Description
Zbtlink WE1326, WE357, WE5926, WE5926-WD, WE826-Q, WE826-T2, WE826-WD, WG108, and WG3526 firmware 19.1101, Zbtlink WE2426-C firmware 19.1112, Zbtlink WE5926-EC_QP firmware 20.0516, Zbtlink WF3526-P firmware 19.051, CTN720-W1, LF-1541, and MT7620N firmware 19.1101, and WRC1 firmware 20.0622 contain an unauthenticated command injection in the infosrvd service (UDP/9992). A remote unauthenticated attacker can send a crafted UDP packet to execute arbitrary commands as root. The service's authentication uses a hardcoded salt and an all-zero wildcard MAC bypass, rendering it ineffective.
