CVE-2023-53894

Estado: AnalizadaCrítica (9.3)—

phpfm 1.7.9 contains an authentication bypass vulnerability that allows attackers to log in by exploiting loose type comparison in password hash validation. Attackers can craft specific password hashes beginning with 0e or 00e to bypass authentication and upload malicious PHP files to the server.

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.

Acceso remoto sin autenticación (AV:N, PR:N, UI:N) en aplicación web expuesta. Bypass de autenticación permite login no autorizado e inyección de web shell PHP.

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.
