Title: iManager Plugin v1.2.8 (lang) Local File Inclusion Vulnerability
Advisory ID: ZSL-2011-5042
Type: Local/Remote
Impact: Exposure of System Information, Exposure of Sensitive Information
Risk: (3/5)
Release Date: 16.09.2011

Summary

With iManager you can manage your files/images on your webserver, and it provides user interface to most of the phpThumb() functions. It works either stand-alone or as a plugin to WYSIWYG editors like tinyMCE, SPAW, htmlAREA, Xinha and FCKeditor.

Description

iManager suffers from a file inlcusion vulnerability (LFI) / file disclosure vulnerability (FD) when input passed thru the 'lang' parameter to imanager.php, rfiles.php, symbols.php, colorpicker.php, loadmsg.php, 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.
