CVE-2022-40916

Estado: AnalizadaCrítica (9.8)—

Tiny File Manager v2.4.7 and below is vulnerable to session fixation.

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.

Session fixation en aplicación web expuesta (AV:N, PR:N) permite al atacante secuestrar sesiones, acceder como usuario legítimo (T1078.001), leer archivos del servidor (T1005) y modificarlos (T1565.001). Vector crítico confirma impacto alto.

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.
