Introduction:
=============
The Omnistar Mailer software was developed because of the need that was found in the industry to easily manage 
email marketing campaigns without having much technical experience. After reviewing feedback from various users 
that had used email mailing list managers, it was determined that many of the current solutions that are on the 
market are cumbersome and overly complex. Most users of email marketing solutions desire a simple solution were 
they can easily add email list campaigns and track the success of them. There of course are many other features 
that add value to the products, however the main function is to send out mass emails, manage the opt-in / 
opt-out process. After reviewing the feedback of these users and studying the current solutions on the market, 
we developed what we call Omnistar Mailer. We feel our product combines simplicity with a robust set of features 
and functions that should meet the needs of most users.

The Omnistar Mailer software is one of the flag ship solutions from Omnistar Interactive. Our entire goal when 
developing any of our solutions has been to make it so easy to use, that any non-technical person can successfully 
use the software. Everyday we strive to make more and more improvements to the software so that it becomes better 
and better. To make this goal a reality, we actively solicit feedback from our customers so that we stay on the 
pulse of their needs. It is only through this interactive dialogue that we can implement those features that make 
sense to our customers. It is our customers that drive our development process and make sure that our software has 
the most desired components and features.

Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple Web Vulnerabilities in the Omnistar Mailer v7.2 Email Marketing Software.


Report-Timeline:
================
2012-10-01:	Public or Non-Public Disclosure


Status:
========
Published


Affected Products:
==================
Omnistar Interactive
Product: Omnistar Mailer v7.2


Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
1.1
Multiple SQL Injection vulnerabilities are detected in the Omnistar Mailer v7.2 Email Marketing Software.
The vulnerabilities allow an attacker (remote) or local low privileged user account to execute a SQL commands on the 
affected application dbms. The vulnerabilities are located in the responder, preview, pages, navlinks, contacts, 
register and index modules with the bound vulnerable id & form_id parameters. Successful exploitation of the vulnerability 
results in dbms & application compromise. Exploitation requires no user inter action & without privileged user account.


Vulnerable Module(s):
			[+] /admin/responder
			[+] /admin/preview
			[+] /admin/navlinks
			[+] /admin/pages
			[+] /admin/contacts
			[+] /users/index
			[+] /users/register

Vulnerable File(s):
			[+] /admin/responder.php
			[+] /admin/preview.php
			[+] /admin/pages.php
			[+] /admin/navlinks.php
			[+] /admin/contacts.php
			[+] /user/register.php
			[+] /users/index.php

Vulnerable Parameter(s):
			[+] ?op=edit&id=
			[+] ?id=
			[+] ?form_id=
			[+] ?op=edit&nav_id=
			[+] ?op=edit&id=16&form_id=
			[+] ?op=edit&id=3&form_id=

			[+] ?nav_id=
			[+] ?profile=1&form_id=
			[+] ?form_id=


1.2
A persistent input validation vulnerability is detected in the Omnistar Mailer v7.2 Email Marketing Software.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). 
The persistent vulnerability is located in the Create Website Forms module with the bound vulnerable form name parameters.
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation. 
Exploitation requires low user inter action & privileged user account.

Vulnerable Section(s):
			[+] Customise Interface -> Create Website Forms

Vulnerable Module(s):
			[+] Create Standard Registration Form -> Add form 

Vulnerable Parameter(s):
			[+] Form Name


Proof of Concept:
=================
1.1
The SQL injection vulnerabilities can be exploited by remote attackers without user inter action. For demonstration or reproduce ...

http://127.0.0.1:1337/mailertest/admin/pages.php?op=edit&id=16&form_id=2'
http://127.0.0.1:1337/mailertest/admin/contacts.php?op=edit&id=3&form_id=2'
http://127.0.0.1:1337/mailertest/users/index.php?profile=1&form_id=2'
http://127.0.0.1:1337/mailertest/users/register.php?form_id=2'

--- SQL Exception ---
SQL error (You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for the right syntax to use near ''9''' at line 3)
in (
select navname,form_id,auto_subscribe,approve_members,confirm_email,signup_redirect,email_forward
	    from mailer75_navlinks
	    where nav_id='9''
)



1.2
The persistent input validation vulnerability can be exploited by remote attackers with low required user inter action & low 
privileged user account. For demonstration or reproduce ...

The attacker create a form and insert in "form name" field own malicious javascript or html code.
To create the form the attacker should to go to 
Customise Interface -> Create Website Forms -> Create Standard Registration Form -> Add form 
Then inject the malicious script code i.e., <iframe src=www.vuln-lab.com onload=alert("VL")/>
When the user browses the forms page in the control panel, or any user trying to register for the website, 
the persistent injected script code will be executed out of the web application context.


Risk:
=====
1.1
The security risk of the  blind SQL injection  vulnerability is estimated as critical.

1.2
The security risk of the persistent input validation vulnerability is estimated as medium(+).
