Hi guys.

Is there any effective way bypassing character filters? Hex encoding and such don't work.

There is a site previously keen on mysql injection, now it is patched with character detection. Whenever I try some characters like +, ' etc (even if they are encoded in hex) a message is displayed "no sql injection please".

Any hints?

Thanks

Try using upper case letters.

Code:

UNION SELECT 1,2,3 FROM


or replacing spaces with /**/

Code:

UNION/**/SELECT/**/1,2,3/**/FROM
