CVE-2026-71910

Multiple DrayTek VigorAP models contain a command injection vulnerability in the apautotest function. The vulnerability is caused by insufficient validation of the CMD0, CMD3, and CMD6 fields before command execution. 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 apautotest. La vulnerabilidad es causada por una validación insuficiente de los campos CMD0, CMD3 y CMD6 antes de la ejecución de comandos. 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.
