- Summary
- [none]
- Details
-
When multiple server blocks are configured to share the same IP address and port, an attacker can use session resumption to bypass client certificate authentication requirements on these servers. This vulnerability arises when TLS Session Tickets https://nginx.org/en/docs/http/ngxhttpsslmodule.html#sslsessionticketkey are used and/or the SSL session cache https://nginx.org/en/docs/http/ngxhttpsslmodule.html#sslsession_cache are used in the default server and the default server is performing client certificate authentication.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
