This article describes how to use a custom event handler in FortiAnalyzer to raise alerts for incident response related to attacks that attempt to leverage the FortiOS heap-based buffer overflow in sslvpnd (FG-IR-22-398). A report is also provided to gain historical visibility into your logs.


Note that this article provides alpha files which are automatically generated. The article will be continually updated as more information becomes available.


This article contains the files necessary to load an event handler and report into your FortiAnalyzer for either a Fabric ADOM or a FortiGate ADOM. The Fabric report and event handler leverage logs from other Fortinet products that can be used to detect the attack in addition to FortiGate logs.
