         CVE Name       Pending

    Description  The Asterisk HTTP server currently has a default
                 configuration which allows the BEAST vulnerability to be
                 exploited if the TLS functionality is enabled. This can
                 allow a man-in-the-middle attack to decrypt data passing
                 through it.

    Resolution  Additional configuration options have been added to Asterisk
                which allow configuration of the HTTP server to not be
                susceptible to the BEAST vulnerability. These include
                options to confirm the permitted ciphers, to control what
                TLS protocols are allowed, and to use server cipher
                preference order instead of client preference order. The
                default configuration has also been changed for the HTTP
                server to use a configuration which is not susceptible to
                the BEAST vulnerability.
