CVE-2026-71904

Multiple DrayTek VigorAP models contain a command injection vulnerability in the tr069TestInform function. The vulnerability is caused by insufficient filtering of dangerous characters before the event_code field is concatenated into a system command. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.

Summary		(es) Múltiples modelos DrayTek VigorAP contienen una vulnerabilidad de inyección de comandos en la función tr069TestInform. La vulnerabilidad es causada por un filtrado insuficiente de caracteres peligrosos antes de que el campo event_code sea concatenado en un comando del sistema. Un atacante remoto puede activar esta vulnerabilidad a través de una entrada manipulada para ejecutar comandos arbitrarios con privilegios de root. La explotación requiere credenciales administrativas válidas para la interfaz de gestión web del dispositivo.
