CVE-2020-25276
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in PrimeKey EJBCA 6.x and 7.x before 7.4.1. When using a client certificate to enroll over the EST protocol, no revocation check is performed on that certificate. This vulnerability can only affect a system that has EST configured, uses client certificates to authenticate enrollment, and has had such a certificate revoked. This certificate needs to belong to a role that is authorized to enroll new end entities. (To completely mitigate this problem prior to upgrade, remove any revoked client certificates from their respective roles.)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePrimeKey EJBCA fails to perform certificate revocation checks when using client certificates for EST protocol enrollment. A revoked certificate belonging to a role authorized to enroll new end entities can still be used for authentication, allowing continued enrollment access after the certificate should have been blocked.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check EJBCA installed versionLocate the EJBCA version information in the admin web interface under 'System Configuration' > 'About', or check the version from the command line using 'jboss-cli.sh' or by examining the deployed war file name in the application server's deployment directory.Affected if The installed version is 7.0.0 through 7.3.x (any version >= 7.0.0 but < 7.4.1)
-
Verify EST protocol is enabledIn EJBCA admin web interface, navigate to 'Protocol Configuration' > 'EST' and check if the EST protocol is enabled, or review the ejbca.properties configuration file for 'est.enabled=true'.Affected if EST protocol is enabled and configured for use
-
Confirm EST enrollment uses client certificate authenticationIn EJBCA admin web interface, review the EST configuration under 'Protocol Configuration' > 'EST' and check if 'Client Certificate Authentication' is set, or examine the est.properties configuration for certificate-based enrollment settings.Affected if EST is configured to authenticate using client certificates
-
Identify EST-authorized roles with enrolled client certificatesIn EJBCA admin web interface, go to 'Access Control' > 'Roles' and identify roles that have EST enrollment permissions, then list the certificates bound to those roles. Alternatively, query the database tables 'RoleMember' and 'UserCertificate' to find users with EST-related roles.Affected if There are roles configured with EST enrollment permissions that have associated client certificates
-
Verify revocation status of EST-authorized client certificatesUse EJBCA's 'Search Certificates' function or query the Certificate Revocation List (CRL) distribution point to check whether any client certificates bound to EST-authorized roles appear in revocation lists, or use OpenSSL to check each certificate against the CA's CRL.Affected if Any client certificate authorized for EST enrollment appears in a CRL but is still assigned to an active role
You are affected if EJBCA version is 7.0.0 through 7.3.x, EST protocol is enabled with client certificate authentication, and any revoked certificates are still assigned to EST-authorized roles.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data7.4.1
Remove any revoked client certificates from their respective authorized roles, or upgrade to EJBCA 7.4.1 or later which includes the revocation check.
