🎯 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 movement65 %
Impacto principalT1078.004 Cloud Accountsstealth · persistence · privilege escalation · initial access72 %
Impacto secundarioT1565.001 Stored Data Manipulationimpact58 %

AV:N con PR:L indica explotación de servicio remoto sin privilegios elevados (T1210). Falta de autorización permite escalada de privilegios en proyecto (T1078.004). Sobrescritura de plantillas de notificación constituye manipulación de datos (T1565.001).

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.
