We know that a web application having an authentication page (form-based) should send a 302 Redirection response upon a successful login attempt. (this is to avoid the possibility of a re-post by the attacker) However, the same should be applied to unsuccessful login attempts, too. Because if a client enters wrong credentials and get an error page with 200 OK, a re-post is possible, only providing the wrong credentials to an attacker. And these wrong credentials might just have been slightly mistyped (for example, because of wrong keyboard layout or capslock) and still valuable to an attacker on a machine with public access left open by a frustrated victim (due to unsuccessful login attempts) ... -pilon __________________________________________________ Do You Yahoo!?
