Mitigation checklist
- To mitigate this issue, avoid using rsync in `openssl mode` or `stunnel mode` for encrypted sessions. Instead, utilize rsync over SSH, which provides robust authentication and encryption mechanisms. For example: `rsync -avz -e ssh /source user@remote:/destination`. This requires SSH to be configured and accessible on both the client and server.
