Synopsis

Description

The Expose component for Joomla!, a third-party component for Flash galleries, running on the remote host is affected by a remote code execution vulnerability within the com_expose/uploadimg.php script due to improper sanitization or verification of uploaded files before placing them in a user-accessible path. An unauthenticated, remote attacker can exploit this issue, by uploading and then making a direct request to a crafted file, to execute arbitrary PHP code on the remote host, subject to the privileges of the web server user ID.
