Estado: AnalizadaAlta (8.8)—

A CWE-321 "Use of Hard-coded Cryptographic Key" in the JWT signing in Q-Free MaxTime less than or equal to version 2.11.0 allows an unauthenticated remote attacker to bypass the authentication via crafted HTTP requests.

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.

CWE-321 (clave criptográfica hardcodeada) en JWT permite bypass de autenticación sin privilegios previos. UI:R + acceso remoto = T1203. Impacto: acceso con identidad válida (T1078.001) y posible escalada de privilegios.

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.
