Multiple cross-site scripting (XSS) vulnerabilities in phpMyAdmin before 2.6.4 allow remote attackers to inject arbitrary web script or HTML via (1) the Username to libraries/auth/cookie.auth.lib.php or (2) the error parameter to error.php.

The SQL install script in phpMyAdmin 2.6.2 is created with world-readable permissions, which allows local users to obtain the initial database password by reading the script.

phpMyAdmin 2.6.2-dev, and possibly earlier versions, allows remote attackers to determine the full path of the web root via a direct request to select_lang.lib.php, which reveals the path in a PHP error message.
