CVE-2023-54347

Estado: AnalizadaAlta (8.7)—

OpenEMR 7.0.1 contains an authentication brute force vulnerability that allows attackers to bypass rate limiting protections by sending repeated login attempts to the main login endpoint. Attackers can submit POST requests with authUser and clearPass parameters to systematically test username and password combinations without account lockout restrictions.

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.

Vulnerabilidad de fuerza bruta contra autenticación en endpoint de login remoto (AV:N, PR:N). Impactos: obtención de credenciales válidas (T1078.001) y potencial takeover de cuentas administrativas (T1556).

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.
