Users are advised to update their HBS immediately
QNAP has addressed half a dozen vulnerabilities affecting its Hybrid Backup Sync (HBS) software.
In a security advisory, the company noted the vulnerabilities were discovered in rsync, an open source file synchronization tool used to transfer and sync files between systems. It supports local and remote operations via SSH, and minimizes data transfer with incremental updates. Many backup solutions use rsync, including Duplicity, Bacula, Rclone, and others.
