    There are two types of malicious payload in this vulnerability. Whether to enable Header Inspection depends on the type of payloads in your services.

    • Type 1: Malicious payloads are included in submitted parameters. In this situation, Header Inspection can be disabled.
    • Type 2: Malicious payloads are included in a custom header field. In this situation, Header Inspection must be enabled to block attacks.

    Type 2 malicious payloads depend on Type 1 malicious payloads so whether to enable Header Inspection is determined by your service requirements.
