Hi Felipe,

Just google for the white paper named "SQL Injection Signatures Evasion".
Think you will find it helpful.

Subject: SQL Injection and MSSQL


Hi all,

With filters like "if the parameter has substring 'SELECT'" a malicious user
can mask the 'select' from a request in ASP?

I mean something like (that i know witch works in MySQL)
"concat(char(1,2,3,4),char(5,6,7))"?

MS SQL Server has anyway to mascarade the querys, like some unicode feature
or string functions?

I just need to know if theres anyway that i can put a select in a query
without typing explicit "select". If there, why?

Many thanks!
