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.
