'Name' => "Log1 CMS writeInfo() PHP Code Injection",
'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.
