The remote web server contains a PHP script that is susceptible to a local file include attack.
The remote host is running RaidenHTTPD, a web server for Windows. The version of RaidenHTTPD installed on the remote host fails to sanitize user-supplied input to the 'ulang' parameter in scripts '/raidenhttpd-admin/workspace.php' and '/raidenhttpd-admin/menu.php' before using it to include PHP code. Provided the server's WebAdmin feature has been enabled, an unauthenticated remote attacker can leverage this issue to view arbitrary files or to execute arbitrary PHP code on the remote host, subject to the privileges under which the server operates, which is SYSTEM by default.
Upgrade to RaidenHTTPD Server 2.0.27 or later.
