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)
