Уважаемые, помогите пожалуйста с эксплуатированием этого эксплойта.

------------------------------------------------------------------

Name : phpBB3 SQL Injection

------------------------------------------------------------------

Date : 27.07.2012

------------------------------------------------------------------

Site : www.phpbb.com

------------------------------------------------------------------

Version : 3.0.10

------------------------------------------------------------------

1) What is it?

This is very nice forum board. You should try it!

------------------------------------------------------------------

2) Type of bug?

SQL Injection (or SQL-info-Leak if You want).

------------------------------------------------------------------

3) Where is the bug?

Vulnerable parameter seems to be 'style' because if we set up this parameter

to 'bigger number' (for example: 111111111) we will get an error, with full SQL

statement.

*updated - dateformat is the second vulnerable parameter!

*updated - post_st is the 3rd vulnerable parameter!

*updated - another one: topic_st

4) PoC traffic from Burp:
