1) Improper authentication (CVE-ID: CVE-2025-23419)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an TLS session resumption when handling client certificate authentication. A remote attacker can bypass authentication process and gain unauthorized access to the application.

Successful exploitation of the vulnerability requires that name-based virtual hosts are configured to share the same IP address and port combination and have TLS 1.3 and OpenSSL. 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.
