Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the automatic update process of Cisco Umbrella Roaming Client for Windows could allow an authenticated, local attacker to install arbitrary, unapproved applications on a targeted device. The vulnerability is due to insufficient verification of the Windows Installer. An attacker could exploit this vulnerability by placing a file in a specific location in the Windows file system. A successful exploit could allow the attacker to bypass configured policy and install unapproved applications.
