# Version: 6.0.7
# Tested on: Windows 10 / Windows 7
# Description:
# Memu Play 6.0.7 suffers from Privilege Escalation due to insecure file permissions
# Prerequisites
# Local, Low privilege access with restart capabilities
# Details
# By default the Authenticated Users group has the modify permission to ESM folders/files as shown below.
# A low privilege account is able to rename the MemuService.exe file located in this same path and replace
# with a malicious file that would connect back to an attacking computer giving system level privileges
# (nt authority\system) due to the service running as Local System.
# While a low privilege user is unable to restart the service through the application, a restart of the
# computer triggers the execution of the malicious file.
