Secunia

Multiple vulnerabilities have been identified in MegaBrowser allowing malicious people to conduct directory traversal and enumerate valid user accounts.

One problem is that the HTTP service doesn't handle requests with "../" sequences correct. Allowing trivial directory traversal.

The other problem is that the FTP service returns different answers when invalid usernames are supplied compared to valid usernames.

This has been reported for version 0.71b.

Solution
There is no immediate solution. Use a different web server or implement a firewall or proxy with URL filtering capabilities to filter malicious request. Make sure that all inactive user accounts are disabled and that active accounts uses strong passwords.
