CVE-2025-64386

Estado: AplazadaAlta (7.7)—

The equipment grants a JWT token for each connection in the timeline, but during an active valid session, a hijacking of the token can be done. This will allow an attacker with the token modify parameters of security, access or even steal the session without the legitimate and active session detecting it. The web server allows the attacker to reuse an old session JWT token while the legitimate session is active.

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.

UI:P (interacción del usuario necesaria) determina T1203. El atacante reutiliza tokens JWT válidos para secuestrar sesiones activas, logrado mediante manipulación de parámetros de seguridad (T1078: acceso a credenciales/sesiones; T1098: modificación de cuentas).

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.
