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.
