Vendor Workaround
In default configurations, this flaw is mitigated by the native revocation verification check (certChainRevokeVerify) which is enabled by default on PKI client connections. Ensure that certificate revocation verification remains enabled (do not set isCertRevocationVerify to false). On the server side, the default TomcatJSS configuration uses JSSNativeTrustManager which is not affected by this flaw.

| Description | A flaw was found in JSS (Java Security Services). The JSSTrustManager class does not verify NSS trust flags when validating CA certificates, allowing certificates present in the NSS database without TRUSTED_CA flags to be accepted as trust anchors for TLS connections. In non-default configurations where certificate revocation checking is disabled, this could allow a man-in-the-middle attacker to forge certificates accepted by PKI client connections. | |
