Airscanner Mobile Security Advisory #05082201: File Transfer Anywhere v3.01 Local Server Password Disclosure Product: TTXN File Transfer Anywhere v3.01 server Platform: Tested on Windows Mobile Pocket PC 2003 Requirements: Mobile device running Windows Mobile Pocket PC with Transfer Anywhere v3.01 installed Credits: Jonathan Read, CISSP Airscanner Mobile Security http://www.airscanner.com Mobile Antivirus Researchers Association http://www.mobileav.org August 22 2005 Risk Level: Medium, a local attacker can view server passwords in plain text. Summary: File Transfer Anywhere is a http based file transfer application. It allows users to transfer files in a FTP server like way but using HTTP. The program can also be used as a webserver. The author’s website is unknown but the software can be found on Handango.com Details: File Transfer Anywhere has a couple of security issues. The first issue is the failure to encrypt passwords being sent via the client to the server. Passwords are sent in plaintext and can easily be sniffed through the air using a wireless packet sniffer (when the connection between the server and client are wireless). The second issue is of greater concern. The server by default is not password protected (which is a security risk in itself), but most people will add a password and tick the save password box to avoid intrusions from unknown clients. Although the program uses **** symbols to hide the password in the programs GUI, it stores the saved password in the local registry in plain text. The password can easily be located using a registry editor tool at the following registry location: [\HKEY_LOCAL_MACHINE\SOFTWARE\TTXN\File Transfer Anywhere] Under this key a value called PASS will have the password as its data. This data should be encrypted as it gives a local attacker information that could allow them to gain full remote control of the device at a later stage.
