CVE-2025-50185

Estado: AplazadaAlta (7)—

DbGate is cross-platform database manager. In versions 6.6.0 and below, DbGate allows unauthorized file access due to insufficient validation of file paths and types. A user with application-level access can retrieve data from arbitrary files on the system, regardless of their location or file type. The plugin fails to enforce proper checks on content type and file extension before reading a file. As a result, even sensitive files accessible only to the root user can be read through the application interface. There is currently no fix for this issue.

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.

DbGate permite lectura de archivos arbitrarios (T1005) incluyendo /etc/shadow (T1552.001) tras autenticación remota (PR:L, AV:N). CVSS HIGH y CWE-29 confirman path traversal. Requiere acceso autenticado a servicio remoto (T1210).

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.
