# Exploit Title: TSplus 16.0.2.14 - Remote Access Insecure Files and Folders Permissions
# Date: 2023-08-09
# Exploit Author: Carlo Di Dato for Deloitte Risk Advisory Italia

TSplus Remote Access (v. 16.0.2.14) is an alternative to Citrix and 
Microsoft RDS for remote desktop access and Windows application 
delivery. Web-enable your legacy apps, create SaaS solutions or remotely 
access your centralized corporate tools and files.
The TSplus Remote Access 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-VirtualPrinter-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:
Everyone:(OI)(CF)(F) and Everyone(F)
Permission: Everyone:(OI)(CI)(F)
