CVE-2025-25234

Estado: AnalizadaAlta (7.5)—

Omnissa UAG contains a Cross-Origin Resource Sharing (CORS) bypass vulnerability. A malicious actor with network access to UAG may be able to bypass administrator-configured CORS restrictions to gain access to sensitive networks.

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.

CORS bypass en aplicación expuesta en red (AV:N, AC:L, PR:N) permite eludir controles de acceso a redes sensibles (proxy/SSRF) y potencialmente leer datos. CWE-942 confirma la naturaleza de control de acceso.

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.
