🎯 Técnicas ATT&CK

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

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation90 %

Vector AV:L/PR:L sin UI:R indica escalada de privilegios local. CWE-59 (insecure temporary file) y CWE-362 (TOCTOU) son patrones de T1068. Microsoft Office puede escribir archivos temporales de forma insegura permitiendo que un usuario con permisos locales los manipule para obtener privilegios eleva

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.
