# Exploit Title: TSplus 16.0.0.0 - Remote Work Insecure Files and Folders Permissions # Date: 2023-08-09 # Exploit Author: Carlo Di Dato for Deloitte Risk Advisory Italia # Vendor Homepage: https://tsplus.net/ # Version: Up to 16.0.0.0 # Tested on: Windows # CVE : CVE-2023-31068 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: Permission: Everyone:(OI)(CI)(F) C:\Program Files (x86)\TSplus-RemoteWork\Clients\www C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\cgi-bin C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\download C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\downloads C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\prints C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\var C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\cgi-bin\remoteapp C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\downloads\shared C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5 C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\imgs C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\jwres C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\locales C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\own C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\imgs\des C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\imgs\key C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\imgs\topmenu C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\imgs\key\parts C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\img C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\img\cp C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\img\srv C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\images C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\images\bramus C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\js\prototype C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\var\log ------------------------------------------------------------------------------------------- Permission: Everyone:(F) C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\robots.txt C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\cgi-bin\hb.exe.config C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\cgi-bin\SessionPrelaunch.Common.dll.config C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\cgi-bin\remoteapp\index.html C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\download\common.js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\download\lang.js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\download\Setup-RemoteWork-Client.exe C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\jwres\jwwebsockify.jar C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\jwres\web.jar C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\own\exitlist.html C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\html5\own\exitupload.html C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\index.html C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\img\index.html C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\img\port.bin C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\jws.js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\sha256.js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\java\third\js\prototype\prototype.js C:\Program Files (x86)\TSplus-RemoteWork\Clients\www\software\js\jquery.min.js
