appRain CMF v0.1.5 - Multiple Web Vulnerabilities

概述:

=============

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.

技术分析:

========

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.2cto.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.2cto.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.
