Description:
A vulnerability has been identified in RNN Guestbook, allowing malicious people to access the administrative interface and execute arbitrary commands.

1) RNN Guestbook fails to verify if the user is logged in. This allows malicious people to access all administrative functions without authenticating.

2) The name of the guest book data file is not properly verified, allowing malicious administrators to inject shell meta characters. This can be exploited to execute arbitrary code.

3) The administrative password i written in a "hidden" HTML field even if the administrator didn't authenticate.
