This vulnerability ariseswhen TLS Session Ticketshttps://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_session_ticket_key are used and/or the SSL session cachehttps://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_session_cacheare used in the default server and the default server is performing clientcertificate authentication.Note: Software versions which have reached End of Technical Support (EoTS)are not evaluated.
