CVE-2026-0234

Estado: En análisisAlta (7.2)—

An improper verification of cryptographic signature vulnerability exists in Cortex XSOAR and Cortex XSIAM platforms during integration of Microsoft Teams that enables an unauthenticated user to access and modify protected resources.

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.

Vector de red sin autenticación (AV:N/PR:N) permite explotación remota de verificación criptográfica deficiente en integración Teams. La falta de firma válida permite acceso y modificación de recursos protegidos (T1553.006 + alteración de datos).

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.
