Titel:	Nginx 1.11.4 - 1.27.3 TLS Session Resumption Vulnerability
Zusammenfassung:	Nginx is prone to a TLS session resumption vulnerability.
Beschreibung:	Summary: Nginx is prone to a TLS session resumption vulnerability. Vulnerability Insight: 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 and/or the SSL session cache is used in the default virtual server and the default virtual server is performing client certificate authentication. This issue affects both the NGINX http and NGINX stream modules. Vulnerability Impact: This vulnerability can lead to the exposure of resources or functionality to unintended actors, possibly providing attackers with limited access to sensitive information. Affected Software/OS: Nginx versions 1.11.4 through 1.27.3. Solution: Update to version 1.26.3, 1.27.4 or later. CVSS Score: 4.0 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:N/A:N
