NVDhttps://nvd.nist.gov/vuln/detail/CVE-2018-8019
CWEhttps://cwe.mitre.org/data/definitions/295.html

When using an OCSP responder Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 did not correctly handle invalid responses. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS. Users not using OCSP checks are not affected by this vulnerability.

Weakness

The product does not validate, or incorrectly validates, a certificate.
