Improper authorization in Apache Tomcat - CVE-2025-66614

Vulnerability identifier: #VU122998

CSH Severity: High

CVSS v4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2025-66614

CWE-ID: CWE-285

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to bypass client certificate verification.

The vulnerability exists due to Tomcat does not validate that the host name provided via the SNI extension is the same as the host name provided in the HTTP host header field. If there is more than one virtual host configured and the TLS configuration for one of those hosts does not require client certificate authentication, it is possible for a client to bypass the client certificate authentication for the target host by sending different host names in the SNI extension and the HTTP host header field.
