NNTP Service STARTTLS Plaintext Command Injection

This script is Copyright (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote news service allows plaintext command injection while
negotiating an encrypted communications channel.

Description :

The remote news server contains a software flaw in its STARTTLS
implementation that could allow a remote, unauthenticated attacker to
inject commands during the plaintext protocol phase that will be
executed during the ciphertext protocol phase.

Successful exploitation could allow an attacker access to private
newsgroups and reveal a user's credentials.
