B504: Test for SSL use with no version specified

This plugin is part of a family of tests that detect the use of known bad versions of SSL/TLS, please see ../plugins/ssl_with_bad_version for a complete discussion. Specifically, This plugin test scans for specific methods in Python’s native SSL/TLS support and the pyOpenSSL module that configure the version of SSL/TLS protocol to use. These methods are known to provide default value that maximize compatibility, but permit use of the aforementioned broken protocol versions. A LOW severity warning will be reported whenever this is detected.

Config Options:

This test shares the configuration provided for the standard ../plugins/ssl_with_bad_version test, please refer to its documentation.
