🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement75 %
Impacto principalT1552.007 Container APIcredential access85 %
Impacto secundarioT1090.004 Domain Frontingcommand and control60 %

AV:N con PR:L permite explotar servicio remoto (T1210). La exposición de credenciales almacenadas (CWE-918 SSRF) y cambio de URL de integración permite acceso a datos sensibles (T1552.007) y potencialmente proxy/tunneling (T1090.004).

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.
