This technology enables FortiDAST to assess remotely with a high level of confidence if an asset is vulnerable to a specific vulnerability by testing the disarmed exploit against the asset itself.
To configure the scan, you will need to enable the FSE group signature 'ms-msmq' which will select the underlying script: 'CVE-2023-21554 Microsoft Message Queuing Packet Parser Remote Code Execution Vulnerability.
For reference, a step-by-step guide on how to configure FortiDAST to trigger FSE can be found on Fortinet’s blog.
