ASM JSON and impact on violations

Hello Experts

 

If F5 not parsing JSON properly (nested JSON payload) then what is the impact on violations like illegal parameter, illegal meta character in value and particularly attack signatures?

    F5 should parse JSON properly, if the document type is JSOn, and the URL has been configured with a JSON profile.

     

    You can also configure specific parameters (like form post parameters) to be of JSON type for the value.

     

    If you have issues with improper parsing, I would suggest to raise a support case for deeper investigation.
