Lower severity and a low EPSS score (7.56%). Track it; it rarely justifies an emergency change on its own.

Description

SChannel in Microsoft Internet Explorer 6 through 11 does not ensure that a server's X.509 certificate is the same during renegotiation as it was before renegotiation, which allows man-in-the-middle attackers to obtain sensitive information or modify TLS session data via a "triple handshake attack," aka "TLS Server Certificate Renegotiation Vulnerability."
