Estado: AnalizadaCrítica (9.4)—

An administrative user with access to configure webhooks can execute arbitrary commands by configuring and then triggering webhooks containing specific FreeMarker template syntax.

This issue affects all MongoDB Ops Manager 7.0 versions and MongoDB Ops Manager versions 8.0.22 and prior.

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 CVSS con PR:H (requiere privilegios altos) en red sugiere T1210. CWE-77 (improper neutralization de template syntax) permite ejecución arbitraria de comandos mediante webhooks. La confianza es moderada porque se requiere acceso administrativo previo.

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.
