Nice tutorial thx!

I don't understand 1 thing though -
here:
Code
www.cia.gov/news.php?id=1 and (SELECT substring(concat(1,password),1,1) from administrator limit 0,1)=1

Why is substring and concat required? What does substring(concat(1,password),1,1) evaluate to?
Instead of that can't we use just this... ?
Code
www.cia.gov/news.php?id=1 and (SELECT password from administrator limit 0,1)=1

I think that is server related and how it's configured. Try finding some site and give it a go.

I did give it a go at a site. And the one I suggested does not work. Thats why I am all the more curious.

One more questions:
To run UPDATE query, shouldn't this work:
Code
www.cia.gov/news.php?id=1 and (UPDATE sometable SET score=12 WHERE id=3)>0

It doesn't work on a site.

That will not work. >0 is used with ascii when u try to detect character in char. For a blind injection i don't realy tryed to UPDATE table info, but i think that u can modify your query and tru it out, sorry that i couldn't help more.


* - MenTaL_hax0r - Feb 28, 2010

I'm using >0 because the UPDATE query returns the no. of rows affected.


* - v4n1ty - Feb 28, 2010

well blind sql injection doesn't shows the error... so it would probably be helpful when its visible
