CVE-2025-71282

Estado: AnalizadaAlta (8.7)—

XenForo before 2.3.7 discloses filesystem paths through exception messages triggered by open_basedir restrictions. This allows an attacker to obtain information about the server's directory structure.

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.

XenForo expone rutas del servidor mediante mensajes de excepción (CWE-209: Information Exposure). Acceso remoto sin autenticación (AV:N, PR:N) permite obtener información del directorio del servidor.

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.
