Descriptions

Privilege Escalation vulnerability in McAfee Total Protection (MTP) prior to 16.0.30 allows a local user to gain elevated privileges and perform arbitrary file deletion as the SYSTEM user potentially causing Denial of Service via manipulating Junction link, after enumerating certain files, at a specific time.

Una vulnerabilidad de escalada de privilegios en McAfee Total Protection (MTP) versiones anteriores a 16.0.30, permite a un usuario local alcanzar privilegios elevados y llevar a cabo una eliminación arbitraria de archivos como usuario SYSTEM que podría causar una Denegación de Servicio por medio de la manipulación del enlace de Unión, después de enumerar determinados archivos, en un tiempo específico

This vulnerability allows local attackers to create a denial-of-service condition on affected installations of McAfee Total Protection. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the implementation of the QuickClean feature. By creating a directory junction, an attacker can abuse QuickClean to delete a file. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.
