Estado: AnalizadaAlta (7.4)—

A vulnerability was determined in Tenda A18 15.13.07.13. This affects the function parse_macfilter_rule of the file /goform/setBlackRule. This manipulation of the argument deviceList causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized.

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.

Acceso remoto con PR:L en router Tenda; desbordamiento de búfer en parse_macfilter_rule permite ejecución de código y escalada a root. CWE-119/121 confirman overflow.

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.
