Detailsinfo

A vulnerability was found in Keyfactor PrimeKey EJBCA up to 7.8.x. It has been classified as critical. Affected is an unknown code of the component ACME Order Handler. The manipulation with an unknown input leads to a certificate validation vulnerability. CWE is classifying the issue as CWE-295. The product does not validate, or incorrectly validates, a certificate. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in Keyfactor PrimeKey EJBCA before 7.9.0, related to possible inconsistencies in DNS identifiers submitted in an ACME order and the corresponding CSR submitted during finalization. During the ACME enrollment process, an order is submitted containing an identifier for one or multiple dnsNames. These are validated properly in the ACME challenge. However, if the validation passes, a non-compliant client can include additional dnsNames the CSR sent to the finalize endpoint, resulting in EJBCA issuing a certificate including the identifiers that were not validated. This occurs even if the certificate profile is configured to not allow a DN override by the CSR.

The weakness was published 09/14/2022. The advisory is available at support.keyfactor.com. This vulnerability is traded as CVE-2022-34831 since 06/29/2022. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1587.003 by the MITRE ATT&CK project.

Upgrading to version 7.9.0 eliminates this vulnerability.
