CVE-2025-52997

Estado: ModificadaAlta (7.5)—

File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.34.1, a missing password policy and brute-force protection makes the authentication process insecure. Attackers could mount a brute-force attack to retrieve the passwords of all accounts in a given instance. This issue has been patched in version 2.34.1.

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 a interfaz web sin autenticación fuerte (AV:N, PR:N, UI:N). Impacto: obtención de credenciales válidas mediante fuerza bruta contra la ausencia de política de contraseñas y protección anti-brute-force (CWE-307, CWE-521).

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.
