remote file include vulnerability." );

"The installed version of Coppermine Photo Gallery fails to sanitize
user input to the 'f' parameter in the 'docs/showdoc.php' script
before using it in a PHP 'include()' function.  An unauthenticated
attacker may be able to exploit this flaw to view arbitrary files or
to execute arbitrary PHP code, possibly taken from third-party hosts. 

Note that successful exploitation either requires that the remote host
be running Windows or that it have some type of Samba share." );
