CVE-2023-3769Network attack vector

Device reboot via malformed MMS session packets

Published Oct 2, 2023 · Updated Sep 20, 2024

Improper input validation in Ingeteam INGEPAC FC5066 9.0.22.6+6.1.1.22+5.3.1.1 allows remote attackers to reboot the device via MMS. The MMS session-initiation path accepts specially crafted packet data without adequate validation, triggering a denial-of-service condition that reboots the device and its services. Network access to the device is sufficient, and published material does not disclose the responsible function or packet field.
