Penetration Testing for Blind SQL Injection using BBQSQL

SQL (Structured Query Language) is a language for interaction with the database . SQL injection is a web application attack to inject malicious syntax in SQL Queries .

BLIND SQL INJECTION

Blind SQL Injection consists of techniques for exploiting the SQL injection vulnerabilities by performing a Binary search by putting one character at a time. Well this is very time consuming .

An Example of Blind SQL injection is :

Blind SQL Injection Case:

UNAME = "' or (ASCII(SUBSTR(SELECT user(),1,1))>63) --";

PASS = "";

QUERY = "select * from users where pass=md5('"+PASS+"') and uname='"+UNAME+"'";

QUERY evaluates to:

select *

from users where pass=md5('')

and uname='' or (ASCII(SUBSTR(SELECT user(),1,1))>63) --'

select *

from users where pass=md5('') and

uname=''

or (

ASCII(                 << char -> int

SUBSTR(            << slice string

SELECT user()  << current user

,1,1)                       << first char

)>63                       << 63 = '?'

) --'                          << comment

Well we have a lot of tools that can be used for penetration testing for Blind SQL injection :

SQLMAP
SQLNINJA
BSQL Hacker
Mole
Havij …… etc …..

Though during penetration testing , if these tools dont work , mostly we end up writing a custom script . So here is a treat !! BBSQL can simplify tricky blind SQL injection attack .

Blind SQL Injection with BBQSQL

BBSQL can be used to exploit the Blind SQL injection and can help to reach for hidden vulnerabilities .

BBSQL is fast , simple , versatile and extensible .

BBQSQL is a blind SQL injection framework written in Python. It is extremely useful when attacking tricky SQL injection vulnerabilities. BBQSQL is also a semi-automatic tool, allowing quite a bit of customization for those hard to trigger SQL injection findings.

The tool is built to be database agnostic and is extremely versatile. It also has an intuitive UI to make setting up attacks much easier. Python gevent is also implemented, making BBQSQL extremely fast.

Similar to other SQL injection tools you provide certain request information.

Must provide the usual information:

URL
HTTP Method
Headers
Cookies
Encoding methods
Redirect behavior
Files
HTTP Auth
Proxies

Here is a Usage guide for the Tool :
