[sqlmap-users] Filter on period

[<du...@al...>]

So I did a little test on my site where I simply filtered out "." 
(period) in incoming GET parameters that were vulnerable to SQLi.
sqlmap then failed to list databases, tables and columns.
Since INFORMATION_SCHEMA.TABLES would become INFORMATION_SCHEMATABLES 
and fail with a "Table testdb.INFORMATION_SCHEMATABLES doesn't exist".
Can sqlmap bypass this somehow? I have played around with tamper a bit, 
but haven't bypassed it yet (haven't tried all tamper scripts though, 
only some that sounded logical to try).

Note: I don't see this as a means to protect my sites in the future. 
It's just a little late Sunday night sqlmap fun :)

Cheers!
