CVE-2025-57071

Estado: AnalizadaAlta (7.5)—

Tenda G3 v3.0br_V15.11.0.17 was discovered to contain a stack overflow in the vpnUsers parameter in the formAddVpnUsers function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

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 overflow en parámetro vpnUsers (CWE-121) en firmware de router accesible remotamente. Vector CVSS N/N/N/H permite DoS remoto sin autenticación (T1499.001: consumo de recursos del servidor).

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.
