A vulnerability was identified in Tenda W20E 15.11.0.61068_1546_841_CN_TDC. This issue affects the function formIPMacBindAdd of the component HTTP Handler. Such manipulation of the argument IPMacBindRule leads to stack-based buffer overflow. It is possible to launch the attack remotely.

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-based buffer overflow en handler HTTP remoto con PR:L (acceso autenticado). Puede causar DoS por crash. Sin evidencia de RCE explícita, se asume T1499.004 (application exhaustion).

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.
