Description

This article describes how to use a custom event handler in FortiAnalyzer to raise alerts for incident response related to attacks that attempt to exploit the TotalFlow path traversal and command injection vulnerability in some ABB products.

A report is also provided to gain historical visibility into the logs.

Scope

This article contains the files necessary to load an event handler and report into the FortiAnalyzer for either a Fabric ADOM or a FortiGate ADOM.

The Fabric report and event handler leverage log from other Fortinet products that can be used to detect the attack in addition to FortiGate logs.

 

It is possible to find more details in this Threat Signal Report:
