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.
