CVE-2025-50635

Estado: AnalizadaAlta (7.5)—

A null pointer dereference vulnerability was discovered in Netis WF2780 v2.2.35445. The vulnerability exists in the FUN_0048a728 function of the cgitest.cgi file. Attackers can trigger this vulnerability by controlling the CONTENT_LENGTH variable, causing the program to crash and potentially leading to a denial-of-service (DoS) attack.

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.

Vector CVSS muestra AV:N/PR:N/UI:N sin requisitos de autenticación (red remota sin privilegios) → T1190. Dereference nulo controlable por parámetro CONTENT_LENGTH causa crash → T1499 (DoS).

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.
