🎯 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 principalT1078 Valid Accountsstealth · persistence · privilege escalation · initial access70 %
Impacto secundarioT1565.001 Stored Data Manipulationimpact65 %

Vector CVSS con AV:N, PR:L, UI:N indica acceso remoto autenticado sin interacción (T1210). Improper permission checks en pipeline permite escalada de privilegios y manipulación de datos (T1078 primario, T1565.001 secundario).

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.
