DescriptionA 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.

Workarounds

CNA: 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.
