A vulnerability classified as critical was found in Belkin F9K1122 1.00.33. Affected by this vulnerability is the function formL2TPSetup of the file /goform/formL2TPSetup of the component webs. The manipulation of the argument L2TPUserName leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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.

Stack buffer overflow en endpoint remoto (formL2TPSetup) con PR:L permite RCE. Acceso red+privilegios=T1210; ejecución de código=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.
