CVE-2021-47718

Estado: AnalizadaAlta (8.7)—

OpenBMCS 2.4 contains an information disclosure vulnerability that allows unauthenticated attackers to access sensitive files by exploiting directory listing functionality. Attackers can browse directories like /debug/ and /php/ to discover configuration files, database credentials, and system information.

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:N/PR:N/UI:N permite acceso remoto sin autenticación (T1190). VC:H revela información sensible: credenciales de BD y configuración (T1005, T1552.001 - credenciales almacenadas en archivos de configuración).

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.
