photo gallery that allows easy photo management and complete
administration via a web based interface. This interface offers many more

MM_rsUser.Source = "SELECT username, password"
If MM_fldUserAuthorization < > "" Then MM_rsUser.Source = MM_rsUser.Source
& "," & MM_fldUserAuthorization
MM_rsUser.Source = MM_rsUser.Source & " FROM users WHERE username='" &
MM_valUsername &"' AND password='" & CStr(Request.Form("password")) & "'"

malicious user to inject arbitrary SQL commands into the query.
