Description

This security bulletin contains information about 1 security vulnerability.


1) Improper Authentication (CVE-ID: CVE-2022-41316)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the Certificate Revocation Lists (CRLs) implementation, which prevented Vault from denying access to users with revoked certificates without application reboot. As a result, when using TLS certificate authentication, Vault did not correctly perform CRL revocation checks if login occurred between Vault startup (or invalidation) and a manual retrieval of the CRL, allowing users to continue using the application with revoked certificates.
