This is a critical misconfiguration in the way the browser validates the identity of the server. It negates the use of HTTPS as a secure channel, allowing for Man-in-the-Middle attacks, stealing sensitive information or modifying incoming and outgoing traffic. NOTE: This vulnerability is in an end-of-life product that is no longer maintained by the vendor.
