Abstract:
=========
Vulnerability-Lab researcher discovered multiple web vulnerabilities on the 3rd party web application - Facebook NYClubs (apps.facebook.com).


Report-Timeline:
================
2012-02-15:	Vendor Notification
2012-02-16:	Vendor Response/Feedback
2012-02-16:	Developer Notification by Facebook Security
2012-02-17:	Public or Non-Public Disclosure


Status:
========
Published


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


Severity:
=========
High


Details:
========
1.1
A remote SQL Injection Vulnerability is detected on the Facebook NYClubs application (apps.facebook).
The vulnerability allows an attacker (remote) to inject/execute own sql statements on the affected fb application dbms.
Successful exploitation can result in a stable application, service or dbms compromise.

Vulnerable Application(s): 
			                            [+] NYClubs - Facebook 3rd Party Application

Vulnerable Module(s): 
			                            [+] Messagebox


Affected Service(s): 
			                            [+] apps.facebook.com/nyclubs/


--- Exception/Error Logs ---
INSERT INTO reviews (club_id, ip, name, fbid, location, email, rating, content, active, approved) VALUES (652,`121.112.203.222 ` 
Sven R-m,100001940496405,`x014831@...il.com`,10,`>` iiiiiiiii-(Rated 9/10)

1.2
A client side Cross Site Scripting Vulnerability is detected on the Facebook NYClubs application (apps.facebook).
The vulnerability allows an attacker (remote) to hijack sessions & manipulate client-side application requests with 
high required user inter action.

Vulnerable Module(s): 
			                            [+] ?r=sregion&d=


Picture(s):
			                            ../2.png


Proof of Concept:
=================
The vulnerabilities can be exploited with & without high required user inter action. For demonstration or 

reproduce ...

1.1
Vulnerable:	[MessageBox Input] ---> Include a frame to the local app website & extract the error log

Tables: 	club_id, ip, name, fbid, location, email, rating, content, active, approved
IP:		121.112.203.222
NAME:		Sven R-m
Mail:		x014831@...il.com
Limit:		10--
Type:		Order by Injection
