3. Description:
Red Hat Certificate System is an enterprise software system designed to
manage enterprise public key infrastructure (PKI) deployments. PKI Core
contains fundamental packages required by Red Hat Certificate System, which
comprise the Certificate Authority (CA) subsystem.
Security Fix(es):
* It was found that a mock CMC authentication plugin with a hardcoded
secret was accidentally enabled by default in the pki-core package. An
attacker could potentially use this flaw to bypass the regular
authentication process and trick the CA server into issuing certificates.
(CVE-2017-7537)
This issue was discovered by Christina Fu (Red Hat).
