CVE-2026-66372

Estado: Pendiente de análisisAlta (7.6)—

The affected products use insufficiently random values, which allows web session tokens to be predictable, bounding token entropy to the seed space.

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:A/PR:N indica red adyacente sin privilegios. CWE-337 (weak randomness) permite predicción de tokens de sesión web, comprometiendo autenticación. Impacto: uso de credenciales de sesión válidas (T1078.001) y potencial acceso con token robado (T1550.001).

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.
