Cross-site request forgery (CSRF) vulnerability in phpMyAdmin before 2.11.7.1 allows remote attackers to perform unauthorized actions via a link or IMG tag to (1) the db parameter in the "Creating a Database" functionality (db_create.php), and (2) the convcharset and collation_connection parameters related to an unspecified program that modifies the connection character set.

phpMyAdmin before 2.11.5 accesses $_REQUEST to obtain some parameters instead of $_GET and $_POST, which allows attackers in the same domain to override certain variables and conduct SQL injection and Cross-Site Request Forgery (CSRF) attacks by using crafted cookies.

Cross-site scripting (XSS) vulnerability in libraries/auth/cookie.auth.lib.php in phpMyAdmin before 2.11.2.2, when logins are authenticated with the cookie auth_type, allows remote attackers to inject arbitrary web script or HTML via the convcharset parameter to index.php, a different vulnerability than CVE-2005-0992.
