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.
The vulnerability is confirmed in version 1.4.2. Other versions may also be affected.
Solution: Update to version 1.4.4.
Provided and/or discovered by: Charlie Eriksen via Secunia.
