CVE Details

Release Date:	2025-02-05
Impact:	Moderate	What is this?

Description

A flaw was found in nginx. When name-based virtual hosts are configured to share the same IP address and port combination with TLS 1.3 and OpenSSL, a previously authenticated attacker can use session resumption to bypass client certificate authentication requirements on these servers. This vulnerability arises when TLS session tickets are used, the SSL session cache is used in the default virtual server, and the default virtual server performs client certificate authentication. (From Red Hat.)
