fduncan · ‎07-05-2023

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 leverage the Apache RocketMQ Remote Command Execution Vulnerability. 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 logs from other Fortinet products that can be used to detect the attack in addition to FortiGate logs.

Solution

What is included in Fortinet_ Apache RocketMQ Remote Command Execution Vulnerability.zip:

Apache RocketMQ Remote Command Execution Vulnerability_event-handler.json.
This event handler helps identify Apache RocketMQ Remote Command Execution Vulnerability detected by FortiGate and other Fortinet products.
Apache RocketMQ Remote Command Execution Vulnerability _report.dat.
This report displays the findings on Apache RocketMQ Remote Command Execution Vulnerability attacks from FortiGate and other Fortinet products.
fgt_ Apache RocketMQ Remote Command Execution Vulnerability _event-handler.json.
The event handler for FortiGate ADOMs is configured for FortiGate logs only.
fgt_ Apache RocketMQ Remote Command Execution Vulnerability _report.dat.
The report for FortiGate ADOMs includes FortiGate charts only.
