CVE-2026-71904

Estado: AplazadaAlta (8.6)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS muestra acceso de red (AV:N) con privilegios altos requeridos (PR:H) sin interacción del usuario (UI:N). CWE-78 es command injection. El atacante inyecta código en el campo event_code, ejecuta comandos arbitrarios con privilegios root (T1059) y logra escalada en el contexto administrativ

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
