CVE-2025-69971

Estado: ModificadaCrítica (9.8)—

FUXA v1.2.7 contains a hard-coded credential vulnerability in server/api/jwt-helper.js. The application uses a hard-coded secret key to sign and verify JWT Tokens. This allows remote attackers to forge valid admin tokens and bypass authentication to gain full administrative access.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 9.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 2.23%
Percentil entre todas las CVEs puntuadas: 82
Fecha de la puntuación: 6/10/2026

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.

Impacto secundarioT1059 Command and Scripting Interpreterexecution85 %

AV:N/AC:L/PR:N permite explotación remota sin privilegios (T1190). Credencial hardcodeada en JWT permite falsificar tokens de admin (T1078.001). Acceso administrativo completo permite ejecución de comandos (T1059).

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.
