CVE-2024-54887

Estado: ModificadaAlta (8)—

TP-Link TL-WR940N V3 and V4 with firmware 3.16.9 and earlier contain a buffer overflow via the dnsserver1 and dnsserver2 parameters at /userRpm/Wan6to4TunnelCfgRpm.htm. This vulnerability allows an authenticated attacker to execute arbitrary code on the remote device in the context of the root user.

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.

Buffer overflow (CWE-120) en parámetros de servicio remoto requiere PR:L (autenticación local), clasificado como T1210. Ejecución arbitraria como root (T1059 primaria) con escalada de privilegios implícita (T1068 secundaria).

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.
