Technical description

The CMP CLI client in KeyFactor EJBCA before 8.3.1 has only 6 octets of salt, and is thus not compliant with the security requirements of RFC 4211, and might make man-in-the-middle attacks easier. CMP includes password-based MAC as one of the options for message integrity and authentication (the other option is certificate-based). RFC 4211 section 4.4 requires that password-based MAC parameters use a salt with a random value of at least 8 octets. This helps to inhibit dictionary attacks. Because the standalone CMP client originally was developed as test code, the salt was instead hardcoded and only 6 octets long.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
