The remote host is running AutoIndex, a free PHP script for indexing files in a directory.

The installed version of AutoIndex fails to properly sanitize user-supplied input to the ‘search’ parameter of the ‘index.php’ script. By leveraging this flaw, an attacker may be able to cause arbitrary HTML and script code to be executed by a user’s browser within the context of the affected application, leading to cookie theft and similar attacks.
