CVE-2025-47295 Siemens CVE debrief

A buffer over-read vulnerability in FortiOS, affecting the Siemens RUGGEDCOM APE1808 industrial platform, may allow a remote unauthenticated attacker to crash the FGFM (FortiGate to FortiManager) daemon via a specially crafted request. Successful exploitation requires rare conditions outside the attacker's control, limiting practical exploitability. The vulnerability was disclosed in CISA ICS Advisory ICSA-24-193-02 on 2024-07-09 and added to this advisory in Revision 7 on 2025-06-10. Siemens has released a vendor fix requiring update of the FortiGate NGFW component to version 7.4.4, available through customer support.

Who should care

Organizations operating Siemens RUGGEDCOM APE1808 industrial platforms with FortiGate NGFW components, particularly in critical infrastructure and OT environments where management plane availability is essential.

Technical summary

The vulnerability exists in the FortiOS FGFM daemon, which handles communication between FortiGate devices and FortiManager. A buffer over-read can be triggered by a specially crafted network request, resulting in daemon crash and loss of management connectivity. Attack complexity is high due to rare conditions required for successful exploitation. The vulnerability affects the FortiGate NGFW component within the Siemens RUGGEDCOM APE1808 platform.

Defensive priority
