Summary

A flaw was found in rubyipmi, a gem used in the Baseboard Management Controller (BMC) component of Red Hat Satellite. An authenticated attacker with host creation or update permissions could exploit this vulnerability by crafting a malicious username for the BMC interface.

This could lead to remote code execution (RCE) on the system. This vulnerability is rated Moderate for Red Hat Satellite because it requires the BMC component to be enabled and configured to use `ipmitool` as the IPMI implementation.

Exploitation is limited to environments meeting these specific configuration and permission requirements. Red Hat severity: Moderate — CVSS 8.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L).

Weakness: CWE-78. Affected Red Hat products: Red Hat Satellite 6.16 for RHEL 8; Red Hat Satellite 6.16 for RHEL 9; Red Hat Satellite 6.17 for RHEL 9; Red Hat Satellite 6.18 for RHEL 9; Red Hat Satellite 6.

Red Hat fixing advisory: RHSA-2026:5971, RHSA-2026:5970, RHSA-2026:5968.
