Wordpress : Security Vulnerabilities Published In 2012 (Code Execution)

Unrestricted file upload vulnerability in html/Upload.php in the FCChat Widget plugin 2.2.13.1 and earlier for WordPress allows remote attackers to execute arbitrary code by uploading a file with a file with an executable extension followed by a safe extension, then accessing it via a direct request to the file in html/images.

** DISPUTED ** wp-admin/setup-config.php in the installation component in WordPress 3.3.1 and earlier does not ensure that the specified MySQL database service is appropriate, which allows remote attackers to configure an arbitrary database via the dbhost and dbname parameters, and subsequently conduct static code injection and cross-site scripting (XSS) attacks via (1) an HTTP request or (2) a MySQL query. NOTE: the vendor disputes the significance of this issue; however, remote code execution makes the issue important in many realistic environments.
