Vulnerability Data

A flaw was found in the Open Cluster Management (OCM) when a user have access to the worker nodes which has the cluster-manager-registration-controller or cluster-manager deployments. A malicious user can take advantage of this and bind the cluster-admin to any…

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 mostly match
prevents

Least-privilege policy definition and enforcement directly limits unsafe privilege combinations while the control also addresses broader policy lifecycle activities.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.3 Segregation of duties mostly match
prevents

Segregation of duties reduces the chance that two distinct privileges can be combined to perform unsafe actions.

A.8.2 Privileged access rights mostly match
prevents

Restricting privileged access rights directly mitigates the risk of privilege chaining.

A.5.15 Access control partial match
prevents

Access control policies can limit the combination of privileges that enable unsafe actions.

A.5.18 Access rights partial match
prevents

Managing access rights helps prevent the accumulation or chaining of privileges that lead to unsafe actions.

A.8.18 Use of privileged utility programs partial match
mitigates

Controlling privileged utility programs reduces opportunities for chaining privileges to perform unsafe actions.

A.8.3 Information access restriction partial match
prevents

Information access restriction limits the ability to combine privileges for unsafe actions.
