Charlie Eriksen has discovered a vulnerability in the Cimy User Manager plugin for WordPress, which can be exploited by malicious people to disclose certain sensitive information.
Input passed via the "cimy_um_filename" parameter to e.g. index.php is not properly sanitised in the "cimy_um_download_database()" function (wp-content/plugins/cimy-user-manager/cimy_user_manager.php) before being used to read files. This can be exploited to disclose the content of arbitrary files via directory traversal sequences.
