CVE-2025-40758

Estado: AplazadaAlta (8.7)—

A vulnerability has been identified in Mendix SAML (Mendix 10.12 compatible) (All versions < V4.0.3), Mendix SAML (Mendix 10.21 compatible) (All versions < V4.1.2), Mendix SAML (Mendix 9.24 compatible) (All versions < V3.6.21). Affected versions of the module insufficiently enforce signature validation and binding checks. This could allow unauthenticated remote attackers to hijack an account in specific SSO configurations.

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:N, PR:N, UI:N en SAML SSO: explotación remota sin privilegios (T1190). Fallo de validación de firma permite falsificar aserciones SAML para secuestrar cuentas (T1078.004 account takeover, T1556.007 SAML manipulation).

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.
