Summary
A flaw was found in the Hashicorp vault. Vault’s PKI mount issuer endpoints did not correctly authorize access to remove an issuer or modify issuer metadata, potentially resulting in a denial of service of the PKI mount. This bug did not affect public or private key material, trust chains, or certificate issuance.
Remediation
For OpenShift Container Platform 4.13 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.openshift.com/container-platform/4.13/release_notes/ocp-4-13-release-notes.html You may download the oc tool and use it to inspect release image metadata for x86_64, s390x, ppc64le, and aarch64 architectures. The image digests may be found at https://quay.io/repository/openshift-release-dev/ocp-release?tab=tags The sha values for the release are: (For x86_64 architecture) The image digest is sha256:74b23ed4bbb593195a721373ed6693687a9b444c97065ce8ac653ba464375711 (For s390x architecture) The image digest is sha256:a32d509d960eb3e889a22c4673729f95170489789c85308794287e6e9248fb79 (For ppc64le architecture) The image digest is sha256:bca0e4a4ed28b799e860e302c4f6bb7e11598f7c136c56938db0bf9593fb76f8 (For aarch64 architecture) The image digest is sha256:e07e4075c07fca21a1aed9d7f9c165696b1d0fa4940a219a000894e5683d846c All OpenShift Container Platform 4.13 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel.

01
What, why and how
HashiCorp Vault's PKI mount issuer endpoints did not correctly authorize access to remove an issuer or modify issuer metadata, potentially resulting in denial of service of the PKI mount. This bug did not affect public or private key material, trust chains or certificate issuance. Fixed in Vault 1.13.1, 1.12.5, and 1.11.9.
What
HashiCorp Vault's PKI mount issuer endpoints did not correctly authorize access to remove an issuer or modify issuer metadata, potentially resulting in denial of service of the PKI mount. This bug did not affect public or private key material, trust chains or certificate issuance. Fixed in Vault 1.13.1, 1.12.5, and 1.11.9.
Why
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.None recorded
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
Likely attack path
a network path → Improper Authorization → disrupt the affected service

Weakness ?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-285: Improper Authorization. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
CVSS vector ?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
