Superset oauth ssl certificate validation failure - apache-superset

We are trying to integrate OAUTH in superset.Superset installation is currently not secure and running on Http, however, SSO end points are SSL enabled. We are getting the error -
HTTPSConnectionPool(host='sso.company.com', port=443): Max retries exceeded with url: /platform-sso-server/token (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')))
Is there a way to disable the SSL certificate verification.
I have tried adding below lines in superset_config.py, but it didn't help.
import ssl
ssl.SSLContext.verify_mode =ssl.VerifyMode.CERT_NONE
I am on superset 1.3.2 version.

could try put these code in supserset_config.py
import ssl
try:
_create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
pass
else:
ssl._create_default_https_context = _create_unverified_https_context

MITM proxy, TLS 1.2 Certificate verification failed

Trying to create my own simple MITM-proxy for the specific app which using TLS 1.2 protocol and connecting to several IP addresses, however got in stuck with the error in the app log "Certificate verify failed". How to solve this problem?
The app using about the following code to check the cert:
X509* cert = SSL_get_peer_certificate( ssl );
X509_STORE_CTX * xCtx = X509_STORE_CTX_new();
X509_STORE_CTX_init( xCtx, (X509_STORE*)Store, cert, NULL );
int res = X509_verify_cert( xCtx );
if( !res ) { /*Certificate verify failed*/ };
I did the following steps to achieve the result:
Created CA root key and self-signed certificate according to this manual. It is a bit outdated, so i have made some changes like md5 to sha256, also I didn't use pass phrase, used different key size and other minor changes.
Created proxy key and certificate using the above Root CA to sign it.
Both certificates have been added to the Local Computer Certificates in Personal and Trusted Root Certification Authorities (not sure if this was necessary). Btw, I'm using Windows 10.
Wrote a simple proxy server using sample code from here. Cert.pem and Key.pem took from the second step.
Changed all IP addresses in the app to 127.0.0.1:443 to see if TLS connection established successfully and we can receive first message with an Application Data.
I believe that connection established properly, because WireShark shows common sequence for establishing a TLS connection: Client/Server hello, Certificate, Client key exchange, two encrypted handshake messages. Moreover, using OpenSSL for testing connection:
openssl s_client -connect localhost:443
allow me to write some message and later successfully receive it using SSL_Read() in proxy server. However, there are some errors:
verify error:num=20:unable to get local issuer certificate
verify return:1
verify error:num=21:unable to verify the first certificate
verify return:1
Verify return code: 21 (unable to verify the first certificate)
Using OpenSSL client to directly connect to the original IP addresses give the same errors, but application works great.
Also the output:
openssl verify -CAfile "signing-ca-1.crt" "cert.crt"
WARNING: can't open config file: /usr/local/ssl/openssl.cnf
e:\MyProg\SSL_serv\Debug\cert.crt: OK
It seems that I missed something important. Could you please tell me how to solve this problem with cert?
One of the very purposes of having certificates, along with certificate authorities, is to prevent MITM. The app you are trying trick does the proper thing and checks the certificate. And it doesn't like your's. Its really that simple.
Is it possible to circumvent it and run MITM on an app anyway? Absolutely! Is it going to be easy? Probably not. What you need to do is to patch the app and remove this certificate check.

Are there any public web services that will check for an MTLS cert and response with application/json

A different thread pointed out a couple of services that would require a client MTLS certificate, accept any cert, and then respond with information about the SSL handshake/certs.
HTTPS test server that checks client certificates
These endpoints both return HTML. Does anyone know of anything similar that returns application/json?
The URLs below will return application/json content upon successfully mutual TLS client certificate authentication. If no authentication is peformed, then HTTP error 403 is returned in the HTTP headers and the response is empty:
https://certauth.idrix.fr/json (TLS 1.2 only)
https://certauth.cryptomix.com/json (TLS 1.2 and TLS 1.3)
The json returned in case of success contains various technical information about the established connection.

WCF service self signed certificate invalid on localhost in iis

This is my first time creating a WCF service. I need to use HTTPS as I will be using MembershipBinding. The steps I have taken up to this point are:
Created a certificate authority using the makecert.exe application - from this I have created a server certificate and a client certificate.
Added the certificate authority to the Trusted Root Certification Authorities within Microsoft Management Console.
Added the client and server certificates to my personal certificates within Microsoft Management Console.
Created a https binding for the service in IIS using the server certificate.
Set the appropriate permissions for the app pool on the server certificate.
Defined the service certificate within the serviceBehaviours node in the web.config.
I am now testing the service using the WCF Test Client but I am getting the message:
Error: Cannot obtain Metadata from https://localhost:444/Service.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: https://localhost:444/Service.svc Metadata contains a reference that cannot be resolved: 'https://localhost:444/Service.svc'. Could not establish trust relationship for the SSL/TLS secure channel with authority 'localhost:444'. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. The remote certificate is invalid according to the validation procedure.HTTP GET Error URI: https://localhost:444/Service.svc There was an error downloading 'https://localhost:444/Service.svc'. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. The remote certificate is invalid according to the validation procedure.
The error suggests that there is an issue trusting the certificate but I have trusted the certificate authority used to create it so I don't know how to resolve it. The service worked fine when I was using http.
Thanks in advance.
As your certificate is self-signed, you need to add a hack to your client call :
using (MyWCFServiceClient client = new MyWCFServiceClient())
{
#if DEBUG
ServicePointManager.ServerCertificateValidationCallback = TrustAllCertificatesCallback;
#endif
client.MyCall();
}
And the definition for TrustAllCertificatesCallback :
internal static bool TrustAllCertificatesCallback(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors)
{
bool isValid = true;
// TODO logic to check your self-signed certifiacte
return isValid;
}
The TrustAllCertificatesCallback callback should be deactivated on your production environement.

Using tls certificate in http_client_config with casablanca (cpprestsdk)

I am stuck with creating a http_client which uses a tls certificate (with a private key) for authentication. The cert is available in the windows certificate store.
Using http_client_config::validate_certificates is not clear to me.
Sample:
http_client_config client_config;
client_config.set_validate_certificates(true);
...
http_client client(U("https://url"), client_config);
The exception I get when trying to call the url is: "WinHttpSendRequest" 12044: A certificate is required
Can someone tell me to use a http_client with a tls cert?
Thank you.

SSL Exception when WebService endpoint url has https

I am getting the below exception when I invoke a jax ws webservice from my application deployed in WebSphere Application Server 6.1
SSL HANDSHAKE FAILURE: A signer with SubjectDN "CN=yyy.com, OU=For Intranet Use Only, OU=Web Hosting, O=xx, L=xx, ST=xx, C=xx" was sent from target host:port "*:9445". The signer may need to be added to local trust store "F://../trust.p12" . The extended error message from the SSL handshake exception is: "No trusted certificate found".
The enpoint url has https.
With the same enpoint url I am able to get a response from SOAP UI(Tool) without any certificate configuration etc..
Could you help me on this ?
I finally was able to fix this small issue.The Server certificate needs to be added to the websphere appserver truststore.This can be done from the admin console of websphere by providing the server domain and port.
