CVE-2023-53967

Estado: AnalizadaCrítica (9.3)—

Screen SFT DAB 600/C firmware 1.9.3 contains an authentication bypass vulnerability that allows attackers to change the admin password without requiring the current credentials. Attackers can exploit the userManager.cgx API endpoint by sending a crafted POST request with a new MD5-hashed password to directly modify the admin account's authentication.

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.

Bypass de autenticación en API expuesta (userManager.cgx) accesible sin credenciales previas (AV:N, PR:N, UI:N). Logra acceso a cuenta admin (T1078) y modificación de credenciales (T1098.002).

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.
