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.

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.
