Re: any sql injection bypass on filters?

[The Dead <th3d34d () gmail com>]

Hi Jacky,

If you send for example a common string, the application with filter it?

Sample: ASC, (case when (2=2) then foo else bar end)

If the application fail to filter it probably you will got an error like:

Unknow column 'foo'....

Try it!
