Subject: SugarSales Multiple Vulnerabilities

|                    SugarSales Multiple Vulnerabilities                |

Date: 12-11-2004
Author: Daniel Fabian
Product: SugarSales (formerly SugarCRM)
Affected Version:  up to 2.0.1c
Vendor: SugarCRM (
Vendor-Status: vendor contacted


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.


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
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


SQL Injection

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.

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):

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

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).


File Inclusion/Remote Command Execution

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):

Include files (possible to exploit when not logged in):
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

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.


Nov. 17: Notified vendor
Nov. 22: Vendor reply
Nov. 24: Release of 2.0.1a, which fixes only SQL Injection
Nov. 25: Notification to vendor that not all vulnerabilities were fixed
         by the patch.
Nov. 28: Supplied vendor with a patch for the file inclusion flaws
Dec. 08: Release of 2.0.1c which still does not fix file inclusion flaws
Dec. 13: Disclosure of the vulnerabilities
