appRain CMF v0.1.5 - Multiple Web Vulnerabilities


Introduction:
=============
appRain is one of the first officially released Opensource Content Management Framework (CMF).
CMF is a new web engineering concept where CMS (Content Management System) and Framework
perform together to produce endless varieties of output in a very limited time.
 
appRain, published with lots of extensive features to reduce our development work time.
It satisfies both Client and Developers with a safe and quality output.

Abstract:
=========
Vulnerability-Lab Team discovered multiple web vulnerabilities on the new appRain CMF v0.1.5
 
 
Report-Timeline:
================
2011-11-19: Vendor Notification
2011-11-13: Vendor Response/Feedback
2011-12-18: Public or Non-Public Disclosure
 
 
Status:
========
Published
 
 
Affected Products:
==================
appRain CMF v0.1.5
 
 
Exploitation-Technique:
=======================
Remote
 
 
Severity:
=========
Critical
 
 
Details:
========
Multiple web vulnerabilities are detected on the new appRain CMF v0.1.5.
 
1.1
A SQL Injection vulnerability is detected on the appRain CMF v0.1.5. The bug allows an remote attacker to inject/execute own sql
statements over the vulnerable param request. Successful exploitation of the bug can lead to dbms & cms compromise.
 
Vulnerable Module(s):
                [+] Forum (SQL Injection)
                 
 
1.2
A non-persistent cross site scripting vulnerability is detected on appRain CMF v0.1.5. The vulnerability allows remote
attackers to hijack skype customer sessions via cross site scripting. Successful exploitation of the client-side vulnerability
can result in session hijacking & account steal (user/customer/moderator/administrator).
 
Vulnerable Module(s):
                [+] Search  (Cross Site Scripting)
 
 
Proof of Concept:
=================
The vulnerabilities can be exploited by remote attackers. For example or reproduce ...
 
1.1
http://www.xxx.com/quickstart/profile/-1%20union%20all%20select%201,2,3,@@version,@@datadir,6,7,8,9,10,11,12,13,14,15,16,17,18,19--
 
1.2
http://www.xxx.com/quickstart/search
POST: Inject anything script related into ss
<form method="post" action="http://www.xxx.com/quickstart/search">
<input type="text" name="ss" class="src-box" value="" />
<input type="submit" class="src-btn" value="Search" />
</form>
 
 
Solution:
=========
1.1
Use the prepared statement class to fix the sql injection vulnerability & filter sql error requests.
Set error(0) to prevent against information disclosure via exceptions or error reports.
 
1.2
Parse the input fields and restrict characters like () > <   \\ /  etc to prevent against script inclusion.
Parse also the vulnerable output sections were the script code is getting executed out of the module context.
 
 
Risk:
=====
The security risk of the SQL injection is estimated as critical.
The security risk of the non-persistent cross site vulnerability is estimated as low(+) because of high required user inter action.
