By the symptoms, it looks like your deployment might be missing the workaround to mark cookies as SameSite=None - and the browser is refusing to send the cookie on the redirect back because the origin (the SAML IdP issuing the redirect) is different from the base URL of your SATOSA instance.

This was added in 7f5f0a1f - can you please make sure your proxy_conf.yaml has the cookies_samesite_compat setting added in this commit?

vladimir-mencl-eresearch avatar Feb 24 '25 02:02 vladimir-mencl-eresearch

Thank you for your quick response. We do have this:

cookies_samesite_compat:
  - ["SATOSA_STATE", "SATOSA_STATE_LEGACY"]

However, I just realized that our instance was running at an old commit a6262597d4d982063acdebd542af79ccd4f829fa, so I have updated it now.

We are using a reverse proxy (nginx). Would this affect anything?

gabrc52 avatar Feb 24 '25 02:02 gabrc52

Reverse proxy should be fine. And 7f5f0a1 was added in 2020, so code you were running already had this.

Can you check whether the cookie set by your SATOSA instance in HTTP response headers when issuing the SAML AuthnRequest is marked as samesite=none - and is returned by the browser when sending in the SAML response?

Either regular browser developer tools or the SAML Tracer plugin (Firefox and Chrome) can help with that.

Can you reproduce the issue, or is it happening only to some of your users? Consistently, or only sometimes?

vladimir-mencl-eresearch avatar Feb 24 '25 02:02 vladimir-mencl-eresearch

It seems to be only some users, probably consistently but not sure. SAML Tracer does show the SameSite=none set by SATOSA.

This is the export from SAML-tracer: https://envs.sh/twc.json

gabrc52 avatar Feb 24 '25 03:02 gabrc52

Sorry, looks like everything is correct in your setup. So you may need to look for a user where this happens reproducibly - and ask them for SAML Tracer capture.

One last shot: can you try with a SAML IdP outside mit.edu domain? For some rules around cookies, browsers compare sites by their registered domain (one level below the public suffix list) - and all of your sites are under mit.edu, which may be causing cookies to be passed even where they would be rejected if the origin and target sites were in different registered domain.

vladimir-mencl-eresearch avatar Feb 24 '25 04:02 vladimir-mencl-eresearch

Thanks a lot! This is the tracer from someone who can reproduce this reliably:

SAML-tracer-export-2025-02-24T05_05_16.100Z.json

If you have a suggestion of a public IdP I can use, we could try that.

gabrc52 avatar Feb 24 '25 05:02 gabrc52

Interesting!

Here, the SATOSA_STATE cookie is only marked Secure, not samesite=none. And the browser then refuses to send it on the way back.

I see several parts surprising.

  • Why would the behaviour of SATOSA be different? Looking at the comments in 7f5f0a1, the behaviour of cookies-samesite-compat might be browser dependent. But the User-Agent header in both traces is the same...
  • Given the user still authenticated through okta.mit.edu (so under the same registered domain), I would expect the cookie to get through even without samesite=none. But browsers keep changing how they interpret this (and the spec is not explicit enough), so we can't exactly call out non-compliance here.

I'd recommend looking into the code inside cookies-samesite-compat to see how it determines when to mark the cookie samesite=none.

Hope this helps.

Cheers, Vlad

vladimir-mencl-eresearch avatar Feb 24 '25 05:02 vladimir-mencl-eresearch

Hi Vlad, thanks a lot for your continued support.

In src/satosa/state.py and function state_to_cookie I have added print statements:

print(f"{samesite=} {name=} {path=} {state=} {type(samesite)=} {samesite=} {secure=} {httponly=} {max_age=}")
print(f"samesite", cookie[name]["samesite"], type(cookie[name]["samesite"]))
print(f"secure", cookie[name]["secure"], type(cookie[name]["secure"]))

Output from the user who can reproduce the error (so samesite is set to None as expected):

samesite=None name='SATOSA_STATE' path='/' state={'SESSION_ID': 'urn:uuid:2cca7a81-c8b1-4790-a8a8-7de842599ca3', 'oidc': {'oidc_request': 'response_type=code&client_id=DFtkQwWabPFO&redirect_uri=https%3A%2F%2Fhkn-tutoring2.mit.edu%2Foauth%2Fcallback&scope=openid+openid+email+profile&state=xSELXF0ewN5n4fPNt5dszZUk'}, 'SATOSA_BASE': {'requester': 'DFtkQwWabPFO'}, 'ROUTER': 'oidc', 'touchstone': {'relay_state': '9YYA2czswquzZvpD'}} type(samesite)=<class 'NoneType'> samesite=None secure=None httponly=None max_age=None
samesite None <class 'str'>

I did not look at the cookies-samesite-compat code yet.

Maintainer of OpenGrades here:

I know of the issue from three different users. The last user, I tried to sign in myself on their device, and got the same error which leads me to think this is a browser issue. All users report that this works fine when using Incognito or another browser. When using the primary Chrome profile, users are facing this issue but opening a new profile (even a Guest profile) avoids the issue. I'm not sure if there's some obscure flag or device problem that leads to this, I'm a little stumped.

Hi @gabrc52 , looking at it again, I don't think the issue would be in cookies-samesite-compat. This code is just to create a copy of the state cookie without the samesite attribute to deal with browsers that might ignore the primary cookie because they do not understand / support the samesite cookie attribute. I don't think that's the culprit here.

I've looked into how state_to_cookie is called from src/satosa/base.py. The parameter samesite is driven by self.config.get("COOKIE_SAMESITE") - and defaults to Python value None.

Thanks for the debug output - that confirms samesite indeed has the Python value None.

And this line in state_to_cookie should make sure cookie[name]["samesite"] is set to String value "None":

    cookie[name]["samesite"] = samesite if samesite is not None else "None"

It is a bit of a mouthful to read out withNone and "None" next to each other - but it reads "if a value is not provided, use string value "None"".

And that is indeed happening - your third debug line shows None <class 'str'>.

So it should be setting the cookie with samesite=None - except that as per the SAML Tracer capture, it does not.

Running out of ideas here...

See this comment: https://github.com/IdentityPython/SATOSA/issues/468#issuecomment-2704662146

An ugly workaround is to use a proxy to strip out all cookies except for the SATOSA session cookie before Python sees the request.
