Performing a manipulation of the argument wifiOff results in os command injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used.

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 con AV:N/PR:N/UI:N indica acceso remoto sin privilegios ni interacción; CWE-78 (OS command injection) en CGI Handler web confirma T1190. Inyección de comandos en parámetro wifiOff permite T1059.

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.
