CVE-2022-30279Network attack vector

Authenticated firmware crash via forged lacbus traffic

Published May 12, 2022 · Updated Aug 3, 2024

NULL pointer dereference in Stormshield Network Security 4.3.3 through 4.3.7 allows remote authenticated users to crash the firmware. When the ASQ sofbus lacbus plugin logs forged sofbus lacbus traffic, its event-logging path dereferences a NULL pointer. Low privileges, network reachability, and enabled request logging are required; exploitation interrupts the firewall by crashing its firmware.
