Abstract:
=========
The independent Vulnerability Laboratory Researcher (X-Cisadane) discovered 
multiple critical Web Vulnerabilities in the AWAuctionScript v1.0 CMS.

Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
1.1
A remote SQL Injection vulnerability is detected in the AWAuctionScript v1.0 
Content Management System Web Application.
The vulnerability allows an attacker (remote) or local low privileged user 
account to execute a SQL commands on the affected application dbms. 
The sql injection vulnerability is located in listing.php file with the bound 
vulnerable PageNo parameter request. Successful exploitation of 
the vulnerability results in dbms & application compromise. Exploitation 
requires no user interaction & without privileged user account.

Vulnerable File(s):
                                [+] Listing.php

Vulnerable Module(s):
                                [+] Category

Vulnerable Parameter(s):
                                [+] &PageNo



1.2
A webshell upload vulnerability is detected in the in the AWAuctionScript v1.0 
Content Management System Web Application.
The vulnerability allows remote attackers to upload own files via a 
misconfigured upload function (restriction).  The bug is 
located in the avatar upload function and the bound vulnerable (accessable) 
thumbnail path. Successful exploitation of the 
vulnerability result in malicious file uploads like webshell, malware and co. 
to compromise the application system itself.

Vulnerable Module(s):
                                [+] Upload Avatar - Edit Account


1.3
A persistent input validation vulnerability is detected in the AWAuctionScript 
v1.0 Content Management System Web Application.
The bug allow remote attackers to implement/inject own malicious script code on 
the application side (persistent). The persistent vulnerabilities 
is located in the login module with the bound vulnerable username parameter. 
Successful exploitation of the vulnerability can lead to session 
hijacking(manager/admin) or stable (persistent) context manipulation. 
Exploitation requires low user inter action & low privileged web 
application user account.

Vulnerable Module(s):
                                [+] Login - User Management

Vulnerable Parameter(s):
                                [+] Username


Proof of Concept:
=================
1.1
The SQL Injection vulnerability can be exploited by remote attackers without 
required user inter action or privileged application user account.
For demonstration or reproduce ...

PoC:
http://[Server]/[PATH]/listing.php?category=Website&PageNo=-1'[SQL-Injection 
Vulnerability!] 

Reference(s):
http://www.xxx.net/listing.php?category=Website&PageNo=-1'[SQL-Injection 
Vulnerability!]

 Vulnerability!]

Vulnerability!]

Vulnerability!]

--- SQL Error Logs ---
1064 You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for the right 
syntax to use near '-12,6' at line 1



1.2
The Upload Shell/Backdoor Vulnerability can be exploited by remote attackers 
without required user inter action 
but with low privileged user application account. For demonstration or 
reproduce ...


Example (Victim/Target) : http://testhacksite.com/
- Prepare your .php backdoor, rename it with index.php3 
- Register to victim site, for example : http://testhacksite.com/ 
- Activate by E-Mail, after Activated login to http://testhacksite.com/login.php
- Go to http://websiterama.com/edit-account.php 
- Upload the avatar, browse your Backdoor/Shell file & upload it!
- Copy the image location/image url of the thumbnail (on the right) 
- Paste in URL. Voilaaaa! http://testhacksite.com/avatar/1031115958.php3



1.3
The persistent and non persistent cross site scripting vulnerabilities can be 
exploited by remote attacker with low privileged 
application user account and medium or high required user inter action. For 
demonstration or reproduce ...

XSS (Non Persistent)

Module(s): 
                        [+] Admin Login page

PoC:                    "><script>alert(/xss/)</script> 

Note:                   Fill username with the poc string and the password with 
anything.


Module(s): 
                        [+] On Listing Page 

PoC:                    http://victim site/<path>/listing.php?category=[Insert 
HTML/XSS Script]

Reference(s): 
                        
http://server.com/listing.php?category=<script>alert(/x-cisadane/)</script> 


XSS (Persistent)

Module(s): 
                        [+] sell-your-site

Requirement(s):         *Must be logged in

PoC:                    http://victim site/<path>/sell-your-site.php

Example (Victim/Target):
- Go to http://www.server.com/sell-your-site.php
- On the Site Name, fill it with this script : <script>alert("Hacked)</script>
- On the Site Description, fill it with this script on from this link 
http://pastebin.com/5mfg7xv4
- Done!


Risk:
=====
1.1
The security risk of the remote sql injection vulnerability is estimated as 
critical.

1.2
The security risk of the webshell upload and restriction bypass vulnerability 
is estimated as high.

1.3
The security risk of the persistent and non-persistent cross site scripting 
vulnerabilities are estimated as medium(+)|(-)high.
