"The remote web server hosts a PHP script that is susceptible to a
cross-site scripting attack.  The script 'install/index.html' does not
properly sanitize input data to the 'lang' parameter before including
it in HTML generated dynamically. 

As a result of this vulnerability, it is possible for a remote
attacker to create a malicious link containing script code that will
be executed in the browser of an unsuspecting user when followed. 

This may facilitate the theft of cookie-based authentication
credentials as well as other attacks.");
