Mitigation checklist
- Disable the rsyncd daemon if it is unused (systemctl disable --now rsyncd), or strictly limit TCP/873 access to trusted clients via firewall rules. Within rsyncd.conf, block the exploit vectors directly by setting refuse options = partial-dir backup-dir and maintain defense-in-depth by enforcing use chroot = yes. Finally, ensure no root- or daemon-owned symlinks point outside your module paths, and avoid using the vulnerable flags when operating as a client against untrusted sources.
