CyberRota Analysis
AI-GeneratedThe Ansible FreeBSD Jail Connection Plugin prior to version 2.0.0 is vulnerable to a symlink attack that allows an attacker controlling content within a managed jail to perform arbitrary root-owned writes on the host system, effectively escaping the jail's confinement. This vulnerability poses a significant risk of host compromise, particularly for environments utilizing Ansible to manage FreeBSD Jails. Organizations using this plugin should prioritize immediate updates to version 2.0.0 to mitigate potential exploitation.

Original NVD Description
Ansible FreeBSD Jail Connection Plugin is an Ansible connection plugin for FreeBSD Jails via jexec. Through version 1.3.0, the jailexec connection plugin's put_file resolved a transfer's destination to a path on the jail host ( + ) and ran mkdir -p and mv there as root on the host. Those commands follow symbolic links, and the path was operated on outside the jail, so a symlink existing inside the jail was followed by the host-side, root-privileged mv. A party controlling content inside a managed jail (the jail's root, or any process able to create a symlink in a directory an Ansible task later writes to) can therefore cause an arbitrary root-owned write on the host, outside the jail — a full jail escape. Arbitrary root-owned host writes are readily escalated to host compromise (e.g. cron, rc.d, authorized_keys). Preconditions for this vulnerability are that the operator runs a copy/template/fetch-style task (anything using put_file) against the jail, and the attacker can place a symlink inside the jail at or above the task's destination before the transfer runs. This issue has been fixed in version 2.0.0.
