CVE-2023-47401 is a critical remote code execution vulnerability in Nagios XI, affecting the migration feature in versions including 5.11.1. According to the provided content, the migration page at /nagiosxi/admin/migrate.php passes attacker-supplied IP address, username, and password values to a PHP migration script executed via sudo as root. A high-privileged attacker can inject attacker-controlled Ansible playbook or vault content into this workflow. Because the injected YAML can invoke Ansible functionality such as lookup("pipe", ...), arbitrary shell commands can be executed on the Nagios XI server with root privileges. The issue is described as an Ansible vault file injection flaw in the migration feature and was mitigated in Nagios XI 5.11.4.
