Affected      Software: PHPXMAIL
Software      Version: 0.7 -> 1.1

Attack:       Authentication Bypass

[...details snipped...]

The problem occurs when we try to log in with an overlong password 
because we get no response message from the server and the function dont

Now when we login with a username like postmaster () localhost and an
overlong password
we bypass the error handler and successfully log in.


Solution: Maybe insert a maxsize tag to the passwords input field.

Erm... a maxsize tag will not prevent the attack at all.
