Summary

A flaw was found in acm-search-v2-rhel9. This vulnerability allows an authenticated attacker, such as a hub administrator or a Search Custom Resource (CR) editor, to inject malicious shell commands or SQL statements.

This occurs because the WORK_MEM string provided in the Search CR is not properly validated before being used in a bash script and an SQL query. Successful exploitation could lead to arbitrary code execution within the privileged postgres pod, potentially compromising the system.

This is due to improper handling of untrusted input in the `WORK_MEM` string, leading to a complete compromise of the cluster's search service with cluster-wide impersonate privileges. Red Hat severity: Important — CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

Weakness: CWE-78.

Affected Red Hat products: Red Hat Advanced Cluster Management for Kubernetes 2.11; Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; Red Hat Advanced Cluster Management for Kubernetes 2.15; Red Hat Advanced Cluster Management for Kubernetes 2.16; Red Hat Advanced Cluster Management for Kubernetes 2.17.
