Zenitel Connect host applies rsyslog configuration written to a volume shared with the hiatus container

Assigner: Zenitel
Reserved: 22.09.2026 Published: 13.11.2026 Updated: 13.11.2026

The host configuration watcher in Zenitel Connect before 1.11.0 applies a rsyslog configuration file written to a data volume that is shared with the hiatus application container, which allows local attackers with write access to the hiatus container filesystem to execute arbitrary OS commands as root on the host operating system via a crafted rsyslog configuration file.
