CVE-2024-39786

Estado: ModificadaAlta (7.2)—

Multiple directory traversal vulnerabilities exist in the nas.cgi add_dir() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to permission bypass. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A directory traversal vulnerability exists within the `adddir_name` POST parameter.

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.

Acceso remoto con privilegios autenticados (PR:H) permite ejecución en servicio remoto; traversal de directorios (CWE-22) en nas.cgi permite lectura y potencial manipulación de datos del sistema.

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.
