The remote web server is vulnerable to a directory traversal attack.
The remote host is running a Apache 2.0.39 for Win32. There is a flaw in this version which allows anyone to access files that would otherwise be inaccessible by a directory traversal attack. An attacker may use this flaw to read sensitive files on this host, or even possibly execute commands on your system.
Upgrade to Apache 2.0.40 or higher for Win32.
