ACM Search V2 RHEL9 Command Injection Vulnerability

Publication date: 2026-08-17

Last updated on: 2026-08-17

Assigner: redhat-SADP

Description
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.

Executive Summary

This is a command injection vulnerability in acm-search-v2-rhel9. An authenticated attacker with hub admin or Search CR editor privileges can inject malicious shell commands or SQL statements via the WORK_MEM parameter. The parameter is improperly validated and concatenated directly into a bash script and SQL query, allowing arbitrary code execution in the privileged postgres pod.

Detection Guidance

Check for unauthorized modifications to the WORK_MEM parameter in Search Custom Resources (CRs) or suspicious activity in the postgresql-start.sh script located at /opt/app-root/src/postgresql-start/postgresql-start.sh. Monitor logs for unexpected shell commands or SQL queries originating from the postgres pod.

Impact Analysis

Exploitation could lead to full system compromise with cluster-wide privileges. Attackers could execute arbitrary commands, access sensitive data, or disrupt services. The postgres pod runs with high privileges, so successful exploitation may allow takeover of the entire cluster.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and system integrity. GDPR and HIPAA mandate strict access controls and protection against unauthorized code execution. A successful exploit could lead to unauthorized data access or modification, resulting in regulatory penalties and loss of compliance certifications.

Mitigation Strategies

Restrict access to hub administrator and Search CR editor roles. Review and validate all Search CR configurations, especially the WORK_MEM parameter. Monitor the postgres pod for unusual activity. Apply any vendor-provided patches or mitigations as soon as they become available.
