CVE-2024-0206

A symbolic link manipulation vulnerability in Trellix Anti-Malware Engine prior to the January 2024 release allows an authenticated local user to potentially gain an escalation of privileges. This was achieved by adding an entry to the registry under the Trellix ENS registry folder with a symbolic link to files that the user wouldn't normally have permission to. After a scan, the Engine would follow the links and remove the files

Summary		(es) Una vulnerabilidad de manipulación de enlaces simbólicos en Trellix Anti-Malware Engine antes del lanzamiento de enero de 2024 permite que un usuario local autenticado obtenga potencialmente una escalada de privilegios. Esto se logró agregando una entrada al registro en la carpeta de registro de Trellix ENS con un enlace simbólico a archivos para los que el usuario normalmente no tendría permiso. Después de un escaneo, el motor seguiría los enlaces y eliminaría los archivos.
