CVE-2026-53548

Estado: AplazadaCrítica (9.6)—

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to 2.6.1, the GET /host/db/host/:id/password endpoint in src/backend/database/routes/host.ts accepts an authenticated user's numeric host ID and the field=password or field=sudoPassword query without enforcing host ownership during credential resolution.

Leer descripción completaMostrar menos

A failed requester-scoped lookup can resolve the host with the owner's context and return the owner's plaintext credential, allowing any authenticated user with a valid JWT to enumerate sequential hosts.id values and retrieve SSH or sudo passwords belonging to other users. The disclosed credentials can then be used to access and control managed systems outside the Termix instance. This issue is fixed in version 2.6.1.

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 a servicios remotos autenticado (PR:L, red, JWT válido). Impacto: lectura de credenciales SSH/sudo (T1552.007), uso para autenticación remota (T1078.001) y acceso a sistemas gestionados vía SSH (T1021.004).

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.
