Description
A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.

Impact

A flaw exists in the search-v2-operator that permits a privileged Custom Resource editor to supply unsanitized values for imageOverride, arguments, and environment variables. By controlling these fields, an attacker can mount arbitrary secrets into a search container’s environment or replace the container image with an attacker‑controlled one. The resulting privilege escalation can lead to full cluster compromise because the ServiceAccount used by the operator impersonates other accounts with broad permissions.

Affected Systems

The vulnerability affects Red Hat Advanced Cluster Management for Kubernetes 2 (acm version 2). No specific sub‑version was listed; any installation using this operator is potentially impacted.

Risk and Exploitability

The CVSS score of 9.1 indicates a high severity, and the EPSS score is not available, so exploitation probability cannot be quantified. The attacker must hold privileges sufficient to create or modify Search Custom Resources. If only such users exist, the risk is high, especially given the operator’s use of a ServiceAccount that can impersonate other accounts. The vulnerability is not listed in the CISA KEV catalog, but the potential impact warrants immediate attention.

Remediation

Vendor Workaround

To mitigate this issue, restrict permissions for creating and modifying Search Custom Resources (CRs) to only trusted and authorized users. Implement Kubernetes Role-Based Access Control (RBAC) policies to limit who can perform `create`, `update`, and `patch` operations on `search.search.open-cluster-management.io` resources. This reduces the attack surface by preventing unauthorized users from exploiting the unsanitized input flow.


OpenCVE Recommended Actions

  • Enforce RBAC policies that allow only trusted users to perform create, update, or patch operations on search.search.open-cluster-management.io resources.
  • Reduce the impersonation scope of the ServiceAccount used by the search‑v2‑operator, removing unnecessary cluster‑wide or Namespace‑wide privileges.
  • Monitor Search Custom Resource changes for unexpected image or environment variable values and apply operator patches or custom validation as soon as available.
