Estado: AnalizadaAlta (7.4)—

An application using Spring Security's WebAuthn support may be vulnerable to user verification bypass when using a distributed HTTP session store. Spring Security 7.1.0 Spring Security 7.0.0 - 7.0.6 Spring Security 6.5.0 - 6.5.11 Spring Security 6.4.0 - 6.4.18

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-863 + bypass de verificación de usuario en WebAuthn = acceso no autorizado. AV:N/AC:H/PR:N permite T1190. Impacto: autenticación eludida (T1078) y manipulación de mecanismo de autenticación (T1556).

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.
