Connection issues when using a certificate #26

Open vlzware opened 6 days ago

vlzware commented 6 days ago

I am connecting to a CheckPoint server for which I have no user/password, but a certificate. The server is on customer's premises and I have no control over it. The OS is Debian 12, a clean install in a VM.

The IP and the certificate seem to be fine, because the Windows client works with them. I use the following to connect with snx-rs:

sudo ./snx-rs -s <the-server-ip> --ignore-server-cert=true --login-type=vpn --cert-path <path-to-mycert.p12> --cert-password="<my_password>" --log-level=debug --tunnel-type=ssl

It fails with error 603, like this:

2024-06-26T14:34:31.124170Z DEBUG snx_rs: >>> Starting snx-rs client version 2.2.4

Error: Request failed, error code: 603

I assume snx-rs doesn't even get to the point where it authenticates, because the output is exactly the same if I omit all certificate-relevant options.

The server responds to "info" like this: sudo ./snx-rs -s <the-server-ip> --ignore-server-cert=true -m info

Supported tunnel protocols:
    IPSec
    SSL
    L2TP
Available login types:
    vpn (vpn)

What might be the reason I am getting rejected with 603? I can connect from the same computer with the Windows client, so the problem seems to be related to the client.

The same command used to work earlier, now it seems something on the server side was changed. What are my options in order to find more information about what exactly is happening?

ancwrd1 commented 6 days ago

There is a new parameter "cert-type" which you need to specify, please see the readme file, certificate authentication section.

vlzware commented 6 days ago

Thanks for your quick response. I added --cert-type pkcs12 and now I got Error: Request failed, error code: 599. Other than the new error code, nothing in the output changed.

ancwrd1 commented 6 days ago

So just to my understanding, was it working before with earlier version? If yes, could you please give me the version number?

ancwrd1 commented 6 days ago

Also please run the following command from the command line and attach the log here (you can redact any sensitive information from it):

curl -k -X POST -d '(CCCclientRequest :RequestHeader ( :id (0) :type (ClientHello)) :RequestData ( :client_info ( :client_type (TRAC) :client_version (1) :client_support_saml (true))))' https://YOUR_VPN_ADDRESS/clients
vlzware commented 6 days ago

The last version which I had was 2.0.2 while the path option was called --client-cert. For what is worth, I can't connect with it now as well - getting the same 599 error code.

The output from the curl request:

ancwrd1 commented 6 days ago

My guess is some of the parameters to authentication call aren't accepted anymore and must be changed. You could perhaps use mitmproxy to intercept the requests from the official application and check what kind of data is sent. I cannot test it because my server doesn't accept certificate authentications. It's not too difficult, you can run mitmproxy on Linux host and let Windows official app to connect to it (instead of your VPN server):

Alternatively you could run mitmproxy on Windows as well.

ancwrd1 commented 6 days ago

And what about IPSec, did you try it?

vlzware commented 6 days ago

Thanks again for your help. This seems like a nice idea - to see what the Windows client does differently. In regards to IPSec - no, it never worked with this server. I'll try the mitm approach and report as soon as I have some data

vlzware commented 4 days ago

mitmproxy crashes when --ssl-insecure is enabled and I need this, because the server uses a self-signed certificate.

I am closing the issue, because as it is I can't provide you with the information you need to fix the problem.

ancwrd1 commented 4 days ago

If you can build the project with Rust compiler (cargo build --release --workspace --exclude snx-rs-gui) try to modify ccc.rs file, lines 66-78 as follows:

Instead of:

            data: RequestData::Auth(AuthRequest {
                client_type: self.params.tunnel_type.as_client_type().to_owned(),
                username,
                password,
                client_logging_data: Some(ClientLoggingData {
                    // Checkpoint gateway checks this and if it's missing or not "Android" the IPSec traffic is blocked
                    os_name: Some("Android".into()),
                    device_id: Some(Uuid::new_v5(&Uuid::NAMESPACE_OID, machine_uuid.as_bytes()).to_string()),
                    ..Default::default()
                }),
                selected_login_option: Some(self.params.login_type.clone()),
                endpoint_os: None,
            }),

Write this:

            data: RequestData::Auth(AuthRequest {
                client_type: "TRAC".to_owned(),
                username,
                password,
                client_logging_data: None,
                selected_login_option: Some(self.params.login_type.clone()),
                endpoint_os: None,
            }),

And see if it helps in any way.

Run it please with trace log level, it will show requests and responses. I think we are close to nail it.

ancwrd1 commented 3 days ago

My guess is that Windows uses IPSec connection and your server doesn't support SSL tunnel anymore. What error do you get when you try IPSec? Can you share trace log?

vlzware commented 3 days ago

It seems you are right in regards of IPSec - according to Wireshark the initial key exchange happens over SSL, then the all the packets are marked as ISAKMP and ESP, which Wireshark tags as UDP Encapsulation of IPsec Packets.

When running snx-rs with --tunnel-type=ipsec I get this:

Error: deadline has elapsed
ancwrd1 commented 3 days ago

In file src/tunnel/ipsec/connector.rs, line 388, try changing client_mode parameter from "SYMBIAN" to "endpoint_security", "secure_connect" or "secure_remote". May be one of them will work.

vlzware commented 3 days ago

Thank you for not giving up on me :)

I tried all three suggestions without success. It is worth noting that the trace still reported "SYMBIAN" in the RequestData field, so I grepped for "SYMBIAN" and found it in "params.rs". I changed there as well, but this didn't help either. The output is the same as earlier with Error: deadline has elapsed at the end.

The CheckPoint client have an option for collecting logs, so I tried digging there and found this - maybe this can shed some more light:

Additionally, I found another server on some other place configured in a similar way - CheckPoint with a password and IPSec. snx-rs fails there in the same way.

ancwrd1 commented 3 days ago

Could you checkout branch 'issue26' and try it with IPSec?

vlzware commented 3 days ago

Still no luck. Tried with both servers with similar results.

Ok, I have added another field, now the request looks exactly like the one sent by my Windows client.

Another thing to check: in the log file (trac.log) of your Windows client, find the message similar to this:

Authentication blob: (
    :clientType (TRAC)
    :client_logging_data (
        :client_build_number (986104605)
        :client_name ("Check Point Mobile")
        :client_ver (E87.20)
        :device_id ("{<redacted>}")
        :device_type (PC)
        :mac_address ("<redacted>")
        :machine_name (PC)
        :os_name ("Windows")
        :os_version (11)
        :physical_ip (10.0.2.15))
    :client_mode (secure_connect)
    :oldSessionId ()
    :protocolVersion (100)
    :selected_realm_id (vpn))

And check is there any visible difference.

Unfortunately, this didn't help either.

and this is from my local VM:

Edit: to clarify a bit - these are both Windows VMs with installed CheckPoint VPN clients and they both connect successfully.

Yeah I am not sure what else can I do here, may be you can try playing with various parameters of the AuthenticationRealm and ClientLoggingData in the source code to bring them closer to what your Windows client sends. For example replace "secure_connect" with "endpoint_security" (in the params.rs).

No worries, you spend a lot of time already - I would try to play alone a bit and will report if I manage to achieve something.

An interesting observation is that the fields in both Windows clients are ordered in the same way but we send the fields sorted in an alphabetical order - could this be an issue - the server expecting the same order of fields?

ancwrd1 commented 2 days ago

Field order shouldn't matter, as well as whitespace formatting.

I have found an issue in the IPSec code, related to certificate authentication. Could you please try the latest main branch and see if it resolves the problem?

vlzware commented 1 day ago

Still no fun. At least the SSL error on my second server is gone. Now both go through the same and at the end is the Error: deadline has elapsed Currently on: 4e4b866 (HEAD -> main, origin/main, origin/HEAD) Updated isakmp dependency

Would be interesting to look in the trac.log from your Windows client, few seconds before and after that "Authentication blob" with client logging.

In particular I am interested in all lines which contain CLIPS::IKElogging category.
