Foreman Command Injection in rake errors:fetch_log Task

Publication date: 2026-10-01

Last updated on: 2026-10-01

Assigner: redhat-SADP

Description
A flaw was found in Foreman. A command injection vulnerability exists in the foreman-rake errors:fetch_log task. The request_id parameter is passed to an underlying system command (typically grep) without adequate shell neutralization. While the task is intended to fetch specific log entries, an attacker with sudo permissions to execute this rake task can inject shell metacharacters (such as ;, ", or |) to break out of the intended command and execute arbitrary code.

Executive Summary

CVE-2026-12540 is a command injection vulnerability in Foreman's foreman-rake errors:fetch_log task. The request_id parameter is passed to a system command like grep without proper shell neutralization. Attackers with sudo permissions can inject shell metacharacters to execute arbitrary code.

Detection Guidance

Check for unauthorized sudo access to the foreman-rake errors:fetch_log task by reviewing sudo logs. Look for commands containing request_id with shell metacharacters like ;, |, or " in logs or command history.

Impact Analysis

An attacker with sudo permissions could exploit this to escalate privileges from a restricted user to the foreman user and then to root. This would compromise the entire Red Hat Satellite server and the infrastructure it manages.

Compliance Impact

This vulnerability could lead to unauthorized access and control of systems, potentially violating compliance requirements for data protection and security such as GDPR and HIPAA due to compromised confidentiality, integrity, and availability of sensitive data.

Mitigation Strategies

Update Foreman to the latest patched version immediately. If no patch is available, restrict sudo access to the foreman-rake errors:fetch_log task and validate request_id input to only allow alphanumeric characters and dashes.
