DescriptionA flaw was found in the Ansible Automation Platform automation controller. The external logging (rsyslog) configuration is generated by interpolating user-controlled settings — LOG_AGGREGATOR_HOST, LOG_AGGREGATOR_MAX_DISK_USAGE_PATH and LOG_AGGREGATOR_RSYSLOGD_ERROR_LOG_FILE — into an rsyslog RainerScript config file without neutralizing RainerScript syntax. A privileged (superuser) user can inject rsyslog directives, including an omprog action, causing arbitrary command execution inside the control-plane rsyslog component. This allows disclosure of the controller SECRET_KEY and database credentials, decryption of all stored credentials, and full compromise of the control plane.
