Summary

Red Hat Enterprise Linux 6, 7, 8, 9 and 10 are affected by this FreeIPA flaw. An improper authorization check (CWE-863) makes FreeIPA verify certificate ownership only by matching the host name to the certificate's subject Common Name. An authenticated enrolled host can therefore retrieve and revoke certificates belonging to other users or services, which can disrupt those services.

Description from the CNA

A flaw was found in FreeIPA. An improper authorization check allows an authenticated host to retrieve and revoke digital certificates assigned to other users or services. This issue occurs because FreeIPA verifies ownership solely by matching the host name to the certificate's subject Common Name (CN), without confirming actual ownership in the directory service. Consequently, an enrolled host can disrupt services by revoking certificates belonging to other entities.
