This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

It was found that a mock CMC authentication plugin with a hardcoded secret was accidentally enabled by default in the pki-core package before 10.6.4. An attacker could potentially use this flaw to bypass the regular authentication process and trick the CA server into issuing certificates.

The bug was discovered 08/02/2017. The weakness was presented 07/26/2018 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2017-7537 since 04/05/2017. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1110.001.

The vulnerability was handled as a non-public zero-day exploit for at least 16 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 103022 (EulerOS 2.0 SP2 : pki-core (EulerOS-SA-2017-1184)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Huawei Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 157526 (Oracle Enterprise Linux Security Update for pki-core (ELSA-2017-2335)).
