CVE-2013-4362

Estado: ModificadaAlta (7.2)—💥 Exploit

WEB-DAV Linux File System (davfs2) 1.4.6.y 1.4.7 permite a atacantes locales ganar privilegios a través de vectores no especificados en (1) kernel_interface.c y (2) mount_davfs.c, en relación con la función "system"

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
