CVE-2024-30637

Unauthenticated command execution via unsanitized MAC parameter

Published Mar 29, 2024 · Updated Aug 2, 2024

Command injection in Tenda F1202 Firmware 1.2.0.20(408) allows remote attackers on an adjacent network to execute arbitrary commands. The formWriteFacMac handler passes the attacker-controlled mac parameter to an operating-system command without neutralizing command delimiters. No authentication or user interaction is required, and successful exploitation compromises the router's confidentiality, integrity, and availability.
