CVE-2024-21914Network attack vector

Unauthenticated terminal restart via unprotected remote action

Published Mar 25, 2024 · Updated Aug 5, 2024

Uncontrolled resource consumption in FactoryTalk View Machine Edition before 14 allows remote attackers to restart PanelView Plus 7 terminals. The terminal accepts a remote restart action without security protections, allowing an unauthenticated request to invoke the reboot operation. Network reachability is sufficient, and a successful restart interrupts the operator's view or control of the HMI until the terminal recovers.
