Apache Tomcat Native OCSP Pre-Produced Responses Authentication Bypass Vulnerability

CVE-2018-8020 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:P/A:N

Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 has a flaw that does not properly check OCSP pre-produced responses, which are lists (multiple entries) of certificate statuses. Subsequently, revoked client certificates may not be properly identified, allowing for users to authenticate with revoked certificates to connections that require mutual TLS. Users not using OCSP checks are not affected by this vulnerability.
