Some vulnerabilities have been reported in FTGatePro, which can be exploited by malicious people to disclose various information and conduct Cross-Site Scripting attacks against users.

1) It is possible to disclose the installation path by connecting to the Web Admin Interface (port 8089/tcp) and request "/utility/wmsecurity.fts". Successful exploitation only requires that a malicious person can connect to the Web Admin Interface. The person doesn't need to be authenticated.

Example:
http://[victim]:8089/utility/wmsecurity.fts

2) Missing validation of input supplied to the "href" parameter in "index.fts" can be exploited to conduct Cross-Site Scripting attacks against other visitors.

Successful exploitation can result in disclosure of various information (eg. cookie-based authentication information) associated with the site running FTGatePro or inclusion of malicious content, which the user thinks is part of the real website.

Example:
http://[victim]:8089/help/index.fts?href=<script>alert(document.cookie)</script>

3) It is possible to identify valid user accounts on the mail server. The problem is that the POP3 service returns different replies depending on whether a supplied username is valid or invalid.

The vulnerabilities have been reported in version 1.22 (1331) and confirmed in version 1.22 (1335). However, other versions may also be affected.

Solution
Ensure that only trusted people can connect to the web interface. Use a HTTP proxy or firewall with URL filtering capabilities to filter malicious content. Restrict access to the POP3 service and use strong passwords.
