GSX Analyzer hardcoded superadmin credentials in Main.swf

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 A few sites externally on the internet are affected by this incident. Presumably all of the externally disclosed GSX analyzer portals have this vulnerability.

Mitigation:

Vendor has been informed on 12-06-16, also CERT has been notified with ID VR-241. Solution is to remove the hardcoded credentials from the SWF file.
