AI-suggested
Red Hat advises restricting the view_jobtemplate permission on job templates with provisioning callback enabled and disabling provisioning callback (clearing host_config_key) on job templates that do not require it. Administrators should set the PROXY_IP_ALLOWED_LIST to include only trusted AAP gateway/envoy addresses to prevent untrusted client X-Forwarded-For headers from being trusted. Any host_config_key values potentially exposed to read-only users should be rotated, and activity stream access reviewed. Monitoring for jobs with launch_type=callback and unexpected limit values or created_by=None is also recommended. These mitigations address the vulnerability effectively.
Description
A critical vulnerability in Red Hat Ansible Automation Platform's automation-controller allows users with only read-level view_jobtemplate permission to access the provisioning-callback secret (host_config_key). The provisioning callback endpoint trusts a client-supplied X-Forwarded-For header when deployed behind the AAP gateway with an empty proxy allow-list. An attacker can exploit this by reading the secret and spoofing the X-Forwarded-For header to impersonate any host in the job template's inventory, enabling them to launch jobs on arbitrary managed hosts with the job template's credentials. This results in privilege escalation and remote code execution on managed hosts.
