CVE-2026-11923

Estado: AnalizadaAlta (7.4)—

IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 and IBM Verify Identity Access Container 11.0 through 11.0.3 Reverse Proxy in certain configurations may provide weaker than expected cryptographic validation of user supplied data.

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 sin UI:R apunta a T1190 (aplicación expuesta). CWE-287 (autenticación débil) + 'validación criptográfica débil' permiten bypass de autenticación (T1078) y potencial manipulación de identidad (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.
