WHMCS 5.0 – Insecure Cookie Authentication Bypass
source: https://www.securityfocus.com/bid/57145/info WHMCS is prone to an authentication-bypass vulnerability because it fails to adequately verify user-supplied input used for cookie-based authentication. Attackers can exploit this vulnerability to gain administrative access to the affected application, which may aid in further attacks. WHMCS 5.0 and 5.1 are vulnerable; other versions may also be affected. http://www.example.com/whmcs/admin/login.php?correct&cache=1?login=getpost{} |
