Red Hat Ansible Automation Platform: spoofing

A flaw was found in Red Hat Ansible Automation Platform's automation-

controller. The provisioning-callback secret (host_config_key) is exposed to

users holding only the read-level view_jobtemplate permission -- both in the

job template API representation and in the activity stream -- and the

provisioning callback endpoint trusts a client-supplied X-Forwarded-For

header to determine the calling host when the controller is deployed behind

the AAP gateway with an empty proxy allow-list. By reading the secret and

spoofing X-Forwarded-For to match any host in the job template's inventory, a

minimally privileged or unauthenticated remote attacker can launch the job

template against arbitrary managed hosts using the job template's credentials,

resulting in privilege escalation and remote code execution on managed hosts.
