CVE-2018-25316

Estado: AnalizadaCrítica (9.3)—

Tenda W308R v2 V5.07.48 contains a cookie session weakness vulnerability that allows unauthenticated attackers to modify DNS settings by exploiting insufficient session validation. Attackers can send GET requests to the goform/AdvSetDns endpoint with a crafted admin language cookie to change DNS servers and redirect user traffic to malicious sites.

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.

AV:N sin autenticación permite acceso remoto directo (T1190). La debilidad de validación de sesión permite falsificar cookies de admin, modificar DNS e inyectar contenido malicioso (T1556: cambio de configuración de dominio; impacto secundario en redireccionamientos T1578).

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.
