normalize_uri() should be used when you're joining URIs. Because if you're merging URIs after it's normalized, you could get double slashes again.

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.
