  # Vendor Homepage: http://www.gsx.com/products/gsx-analyzer
  # Software Link: http://www.gsx.com/download-the-trial-ma
  # Version: 10.12, but also found in version 11
  # Tested on: Windows Server 2008
  # CERT : VR-241
  # CVE : 
  
  1. Description
  
  After decompiling the SWF file "Main.swf", a hardcoded credential in one of the products of GSX, namely GSX Analyzer, has been found. Credential is a superadmin account, which is not listed as a user in the userlist, but can be used to login GSX Analyzer portals. Seemingly a backdoor or a "solution" to provide "support" from the vendor.
   
  The found credentials are:
  Username: gsxlogin
  Password: gsxpassword
  
  2. Proof of Concept
   
  A few sites externally on the internet are affected by this incident. Presumably all of the externally disclosed GSX analyzer portals have this vulnerability.
   
  Code snippet:
  -----------------
  if ((((event.getLogin().toLowerCase() == "gsxlogin")) && ((event.getPwd() == "gsxpassword")))){
  -----------------
  
  3. Solution:
  
  Vendor has been informed on 12-06-16, also CERT has been notified with ID VR-241
