htmlAREA, Xinha and FCKeditor.

Desc: iManager suffers from a file inlcusion vulnerability (LFI) / file

ov_rfiles.php and examples.php is not properly verified before being used
to include files. This can be exploited to include files from local resources
with directory traversal attacks and URL encoded NULL bytes.
