    Hi Oscar77,

    OWASP ruleset has been updated with all our recent NoSQL signatures, covering the example mentioned above and more. Please test again with latest ruleset and let us know the result

    Thanks

    Hi,

    The types of NoSQL injection signatures we have are all the popular operands, similar to $gt which stands for "greater than" and $lt for "less than". We cannot list all the different operands we're searching for due to security concerns.

    Thanks

Hi,

Please send us the full details of the attack test that was not blocked, including sample request. We will analyze the attack test against F5 rule sets to determine the root cause and proposed solution.

Thanks

curl --location --request POST 'URL' \
--header 'token: TOKEN' \
--header 'Content-Type: application/json' \
--data-raw '{
      "link": {
        "$gt": null
      }
    }'

This is my Backend response running curl:

 

{"error":"NoSqlInjectionError","message":"Invalid request","code":0}

But in AWS insights we can see the WAF cannot stop the request, see the >>>> ALLOW <<<<
