Subject: SQL Injeciton.

Thanks I would definitely check on magic_quotes, but the fact is it escapes those characters, so theres no way...its succeptable to sql injection. and ofcourse i am asking this question here means the develper has not done any  kind of sanitization checking. So, if SLQ injection is no possible even below given XXS wont be the case i guess,

'><script>alert('ur hacked')</script>

Thanks,

Gabbar.
