CVE-2023-53740

Estado: AnalizadaAlta (8.6)—

Screen SFT DAB 1.9.3 contains an authentication bypass vulnerability that allows attackers to change the admin password without providing the current credentials. Attackers can exploit the userManager.cgx endpoint by sending a crafted JSON request with a new MD5-hashed password to directly modify the admin account.

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.

AV:A + UI:P sugiere interacción del usuario en red adyacente (acceso a endpoint web). El bypass de autenticación permite cambiar credenciales admin (T1078), impacto directo de la solicitud JSON al endpoint userManager.cgx.

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.
