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!

Hi

I'm currently on a php web application page which issues an error
message when submitting invalid value for "sort" parameter.
But the application  accepts only a-zA-Z for this parameter. I've
tried to bypass it by char(), hex().
If I change its parameter value to a value other than "ASC", "DESC",
the application issues a generic sql error starting with "You have an
error in your SQL syntax".

So, in this situation, can the application still be assumed as
vulnerable to sql injection?

Thank you.
