# Date: 2023-08-09
# Exploit Author: Carlo Di Dato for Deloitte Risk Advisory Italia

With TSPlus Remote Work (v. 16.0.0.0) you can create a secure single
sign-on web portal and remote desktop gateway that enables users to
remotely access the console session of their office PC.
The solution comes with an embedded web server to allow remote users to
easely connect remotely.
However, insecure file and folder permissions are set, and this could
allow a malicious user to manipulate file content (e.g.: changing the
code of html pages or js scripts) or change legitimate files (e.g.
Setup-RemoteWork-Client.exe) in order to compromise a system or to gain
elevated privileges.

This is the list of insecure files and folders with their respective
permissions:
