Some things I'd like to avoid: Object Tag use JavaScript use Windows ...

I'm doing an audit of a system, which the developers insist is SQL injection proof. This they achieve by stripping out the single-quotes in the login form - but the code behind is not parameterized; it's still using literal SQL like so: username = username.Replace("'", ""); var sql = "select * from user where username = '" + username +...

Is there a way to find SQL injection vulnerabilities? Note: I am asking how to find them on a server you are in control of so you can fix them. I am not asking about how to detect them on someone else's server to exploit them. Is there a way to find every occurance of mysql_query() without opening every page and doing a ctrl+f? ...

This is a first line of defense to preventing sql injection. We use other methods for full sql injection prevention. The problem is, when we are collecting data to put together an HTTP post mess...
