| SugarSales Multiple Vulnerabilities |  
-------------------------------------------------------------------------  
  
Date: 12-11-2004  
Author: Daniel Fabian  
Product: SugarSales (formerly SugarCRM)  
Affected Version: up to 2.0.1c  
Vendor: SugarCRM (http://www.sugarcrm.com)  
Vendor-Status: vendor contacted  
  
  
~~~~~~~~  
Synopsis  
~~~~~~~~~~~~~~~~~~~~~~~~  
  
Multiple Vulnerabilities have been found in the open source customer  
relationship management software SugarSales. These vulnerabilities are:  
  
- Full Path Disclosure  
- Install Script  
- File Inclusion/Remote Command Execution  
- SQL Injection  
  
Some of the vulnerabilities described in this advisory can only be  
exploited while logged into SugarSales, however there are also numerious  
flaws that can be exploited by a bypasser without the knowledge of a  
username or password.  
  
  
~~~~~~~~  
References  
~~~~~~~~~~~~~~~~~~~~~~~~  
  
A subset of the vulnerabilities described in this advisory has already  
been independendly discovered by James Bercegay and Damon Wood of the  
GulfTech Security Research Team. Their advisory can be found at  
http://www.gulftech.org/?node=research&article_id=00053-120104.  
As they have been first to post some of these flaws, all credits for those  
vulnerabilities go to them. It's a first come first serve world. However  
as there are some more flaws - most of which can be exploited while not  
logged into SugarSales - we post our advisory in addition.  
  
  
~~~~~~~~  
Vendor Status  
~~~~~~~~~~~~~~~~~~~~~~~~  
  
The vendor has been notified and fixed some of the vulnerabilities we  
have reported in version 2.0.1a. Even though we supplied them with an  
patch for the other vulnerablities, the patch has been neither applied  
to version 2.0.1b nor 2.0.1c. As a result, we are now posting the  
advisory.  
  
  
~~~~~~~~  
Vulnerabilities  
~~~~~~~~~~~~~~~~~~~~~~~~  
  
SQL Injection  
-------------  
  
Scope:  
Due to insufficient input validation, an attacker can manipulate the  
SQL statements that are sent to the database. Two exploits exist for  
this flaw where one can be only used when logged into SugarSales,  
however the other one can be used to log into SugarSales.  
Both of these vulnerabilities have been fixed in version 2.0.1a.  
  
Login:  
An attacker can log into Sugarsales using the username "admin' or 1=1  
-- " (without the double quotes) and any password.  
  
Retrieving Data:  
Once logged in, an attacker can also perform SQL injection to retrieve  
data, using a request such as (to be considered one line):  
http://host/sugarcrm/index.php?action=DetailView&module=Opportunities&  
record=xxx'+union+select+1,2,3,4,5,6,user_name,8,9,10,11,12,13,14,15,16,  
17,user_password+from+users+limit+1,1+--+  
  
Of course as the attacker is already logged in, there is not much use in  
performing this SQL injection anyway. All modules seem to be affected.  
  
  
Full Path Disclosure  
--------------------  
  
Scope:  
A lot of scripts show the full path if unexpected input is encountered.  
This allows an attacker to enumerate the system and locate the webroot.  
This flaw has not yet been fixed (as of version 2.0.1c).  
  
  
Example:  
http://host/Sugarcrm/phprint.php?jt=fe3e158b220567409e5d8976d34bcdae  
&module=&action=&record=&lang=de  
  
  
  
File Inclusion/Remote Command Execution  
---------------------------------------  
  
Scope:  
Due to insufficient input validation of user input that is used in  
include() or require() directives, an attacker is able to disclose  
arbitrary files by specifying their path in certain HTTP GET parameters.  
Two file inclusions can only be exploited while logged into SugarSales,  
however again there are numerious other file inclusion flaws that can be  
used by a bypasser without knowledge of a username or password. As with  
all such file inclusion flaws, remote command execution is just the blink  
of an eye away. If the attacker is able to log in (eg. as described above  
using SQL injection) and upload text files or find the webserver log file,  
he can gain a comfortable web-shell and take control over the server.  
  
Modules and Actions (only possible when logged in):  
http://host/Sugarcrm/index.php?module=/../../etc/hosts%00&action=EditView  
http://host/Sugarcrm/index.php?module=Calls%00&action=/../../etc/hosts%00  
  
Include files (possible to exploit when not logged in):  
http://host/sugarcrm/modules/Users/Login.php?theme=/../../../etc/hosts%00  
http://host/sugarcrm/modules/Calls/index.php?theme=/../../../etc/hosts%00  
This flaw can be found in numerious other files in the modules directory.  
  
Neither of the two flaws has been fixed as of version 2.0.1c.  
  
  
Install Scripts  
---------------  
  
Scope:  
After a successful installation of SugarSales, the install script files  
are not removed or locked, unless manually deleted by the administrator  
of the site. An attacker can use the install scripts to perform a denial  
of service attack by dropping the tables and replacing them with the  
default ones. However more importantly, the MySQL password can be found  
in plaintext on one of the install script forms.  
  
  
~~~~~~~~  
Counter Measures  
~~~~~~~~~~~~~~~~~~~~~~~~  
  
Until a fix is available, set the following parameters in php.ini:  
register_globals = Off  
magic_quotes = On  
  
Manually delete the /install directory.
