Subject: [WEB SECURITY] SQL Smuggling: New methods of SQL Smuggling
To: [email protected]


Hello participants of Mailing List.

In October and November I wrote series of articles about SQL Smuggling and
now I'll post short English versions of them for you. In case if such topic
is interesting for you.

In beginning of the year I read whitepaper of Avi Douglen about SQL
Smuggling (http://www.comsecglobal.com/FrameWork/Upload/SQL_smuggling.pdf).
Which was interesting information for me - I'm using bypassing techniques
for many years and bypassing different WAFs, IPS and IDS all the time from
2006 (for different attacks, including SQL Injection), but I never used such
term as SQL Smuggling. But the term itself looks interesting ;-).

So I decided to write series of articles as about SQL Smuggling, as about
new and advanced methods of it. And after I wrote review of above-mentioned
whitepaper about SQL Smuggling (in October), I wrote article New methods of
SQL Smuggling (http://websecurity.com.ua/4632/).

In this article I told about two new methods of SQL Smuggling (which were
developed after releasing of that whitepaper).

The next ones belong to new methods of SQL Smuggling:

1. Using of specific encoding in SQL query.

Example of such vulnerability in web applications and the attack on it is
SQL Injection vulnerability in WordPress via encoding. The vulnerability was
found by Abel Cheung in 2007.

2. String truncation in MySQL.

The attack on truncation of string in MySQL was developed by Stefan Esser in
2008. Example of using of this attack method is the vulnerability in
WordPress 2.6.1.

In the next post of this series I'll tell you about advanced methods of SQL
Smuggling (which were developed by me).
