Getting a Certificate not accepted message from call to GraphQL in Burp Suite Enterprise.

Glenn | Last updated: May 04, 2021 02:41PM UTC

This is in reference to the problem reported on https://forum.portswigger.net/thread/i-am-having-a-problem-getting-a-graphql-call-to-be-processed-by-our-burp-suite-enterprise-a953216c. I am trying to get a response to my question about what should the parameters be set to on the call to RemoteCertifcateValicationCallback specially the certificate and the chain parameters. If they can't be set, then exactly what should I be doing to get the certificate on my Burp Suite Enterprise server to be accepted by the calling C# program? Thanks.

Hi Glenn, Did you take a look at the latest reply on the other forum post? Can you look at the documentation below for an example of how to implement the RemoteCertifcateValicationCallback? Can you also share an updated PoC? - https://docs.microsoft.com/en-us/dotnet/api/system.net.security.remotecertificatevalidationcallback?view=net-5.0
