Product & Service Introduction:
===============================
MSN (originally The Microsoft Network; stylized as msn) is a collection of Internet sites and services provided by Microsoft. 
The Microsoft Network debuted as an online service and Internet service provider on August 24, 1995, to coincide with the 
release of the Windows 95 operating system. The range of services offered by MSN has changed since its initial release in 1995. 
MSN was once a simple online service for Windows 95, an early experiment at interactive multimedia content on the Internet, 
and one of the most popular dial-up Internet service providers. MSN was primarily a popular Internet portal. Microsoft used 
the MSN brand name to promote numerous popular web-based services in the late 1990s, most notably Hotmail and Microsoft 
Messenger service, before reorganizing many of them in 2005 under another brand name, Windows Live. MSN.com was the 17th most 
visited domain name on the Internet.

Discovery Status:
=================
Published


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


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


Technical Details & Description:
================================
A boolean-based blind SQL Injection web vulnerability has been detected in the official MSN (habitos.be.msn.com) web application Service.
The vulnerability allows remote attackers to inject own sql commands to compromise the affected web-application and connected dbms. 

The SQL Injection vulnerability is located in the item.asp file. The vulnerable parameter to inject the sql commands is `item_id`.
Remote attacker are able to inject own sql commands to the item_id value in the item.asp file GET method request. The issue is a 
blind injection and the attack type is boolean based. The security risk of theremote sql injection web vulnerability 
is estimated as critical with a cvss (common vulnerability scoring system) count of 9.1.

The remote sql injection web vulnerability can be exploited by remote attackers without privileged application user account 
and without required user interaction. Successful exploitation of the sql injection vulnerability results in application and 
web-service or dbms compromise.

Vulnerable Domain(s):
				[+] habitos.be.msn.com

Vulnerable file(s):
				[+] item.asp

Vulnerable Parameter(s):
				[+] item_id


Proof of Concept (PoC):
=======================
The remote blind sql injection vulnerability can be exploited by remote attackers without user interaction or 
privileged web-application user account. For security demonstration or to reproduce the vulnerability follow the 
provided steps and information below. 


Request #1
http://habitos.be.msn.com/item.asp?item_id=98%27%20AND%208606=BENCHMARK(1000000,MD5(0x4964554a))%20AND%20%27xPUE%27=%27xPUE


Request #2
http://habitos.be.msn.com/item.asp?item_id=98%27%20AND%208606=BENCHMARK(5000000,MD5(0x4964554a))%20AND%20%27xPUE%27=%27xPUE


Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure restriction and parse or encode of the vulnerable item_id value GET method request.


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