CVE-2026-71913

Multiple DrayTek VigorAP models contain a command injection vulnerability in the upload_settings.cgi interface. The vulnerability is caused by insufficient filtering before the restorekey field is concatenated into a shell 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 interfaz upload_settings.cgi. La vulnerabilidad es causada por un filtrado insuficiente antes de que el campo restorekey sea concatenado en un comando de shell. 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.
