CVE-2024-9409Network attack vector

Communication loss via IGMP packet flood

Published Nov 13, 2024 · Updated Nov 13, 2024

Uncontrolled resource consumption in Schneider Electric PowerLogic PM5300 Series firmware allows remote attackers to interrupt meter communications. The network stack exhausts an undisclosed resource while processing a large volume of IGMP packets and leaves the meter unresponsive. No authentication or user interaction is required; an attacker with network reachability can cause communication loss, but no data disclosure or modification is reported.
