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.

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.
