F5 OWASP Top Ten Rules, no working NoSQL Injection properly

Hi there, if we do a postman POST request to our Api with the next one body in the request:

 

{

"link": {

"$ne": null

}

},

 

The request is passing using Mentioned rules.

 

How we can solve it?

 

Thanks and have a nice day.

 

  • 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

  • is there another way to obtain "official" support?

     

    We need to fix this, plz

  • 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 <<<<

  • Hi,

     

    We are thinking about to stop using F5 rules in all of multiple environments, because we are worried about a poorly fast support from F5, is a pitty because we loved to use it, but is useless if we cannot obtain support if we need it.
