用户（patron）收到授权错误消息

Hi @caduspa,

Run the below commands in SSH console and try the login again. Let me know if the problem persist.

./launcher enter app
rails c
SiteSetting.patreon_login_ignore_state = true

You are most kind. Sadly, that is above from my level of knowledge. (I’m a classic “tell me which button to push”). I’ll see if I can patch together the know how from a few searches.

I’m having this issue on our community and just made the changes above. I’ll ask for more testing, and let you know what I find out.

I run into this issue, but not with patreon as sign in provider. Everything else seems exactly alike though, the issue is only on mobile devices.

I’m using the OIDC plugin to authenticate through, see: Discourse OpenID Connect (OIDC), to authenticate with Okta.

From the discourse error logs that I can visit at https://discourse.example.com/logs/, I find an error that is logged whenever I reproduce our issue.

I read the following article about it: Web Security Basics - An Introduction to the Essential Concepts Behind a Secure Website

I’m currently not confident about what goes on, but I guess that we are loosing a CSRF token at some point using the mobile auth flow.

This also makes me suspect that SiteSetting.patreon_login_ignore_state = true is an insecure way to bypass the issue we are having.

Error message

(oidc) Authentication failure! csrf_detected: OmniAuth::Strategies::OAuth2::CallbackError, csrf_detected | CSRF detected

Note that CSRF stands for Cross-Site Request Forgery. And from googling I learned that:

CSRF attacks target functionality that causes a state change on the server, such as changing the victim’s email address or password, or purchasing something.

Can confirm we’re seeing very similar things too without using patreon to authenticate - we just use the standard oauth plugin. Only mobile users see this.

47

Here’s a brief outline of how the “state” token is used. It’s part of the OAuth2 specification, so is used for all Discourse’s social login methods, including Patreon, OIDC and OAuth2.

  1. User clicks “login” on Discourse

  2. Discourse generates a random string (a “state token”), and stores it against the user’s browser session

  3. Discourse redirects the user to the auth provider, passing along a copy of the state token

  4. User logs in, and is redirected back to Discourse. The provider passes back the state token

  5. Discourse checks that the received state token matches the one it stored against the user’s browser session earlier. If they do not match, this is considered an CSRF attack.

So, the most likely way this can break in practice, is if the user starts/ends the process in a different browser session. On a desktop this is pretty much impossible, but mobile operating systems tend to have different browser sessions for PWAs vs. browsers vs. native apps, which could be causing this issue.

Do you know whether these users are using the Discourse app, or an ‘installed’ PWA?

48

Thank you for writing down the steps regarding the state @david!

I’m experiencing this with the OIDC plugin, that in turn auths with Okta as IdP, that in turns delegates auth to Azure AD v2.0 OpenID Connect. And it only happens on IPhone as compared to Android devices I think (but this needs to be confirmed further, I have not tested it myself on Android).

It also happens on IPhone no matter if I utilize Safari och Chrome. I have not installed an Discourse app, and I have not utilized discourse on my mobile as an webpage-application (PWA?) but instead simply utilized my Chrome app and opened up my deployed discourse.

49

I’d love to get to the bottom of this, but so far I haven’t managed to reproduce the issue. It’s certainly interesting that you’re seeing this problem with OAuth2 and OIDC, which suggests this issue is not specific to patreon.

@simonv3 and @consideRatio do you have a consistent way to reproduce the issue? And if so, would it be possible for me to access the site in question? (Feel free to PM me if you’d rather not make it public)

50

I have a feeling that this issue could be related to this Safari bug

Fixed Same-Site Lax cookies to be sent with cross-site redirect from a client-initiated load

It was fixed in release 77 of their technology preview, so hopefully it will be part of the next iOS/macOS release.

51

I’ll keep an eye out for similar problems being reported. It hasn’t been reported in a while, but that doesn’t mean it’s not being experienced - probably just that most people know their way around it by now.

52

Heh, just had it reported today. I’ll let them know that maybe it’s a bug in iOS, and ask them if it still happens if/when they upgrade.

53

@simonv3 and @consideRatio, are you still seeing this error? I am hoping that it has been mostly solved by iOS 12.2, but there may still be some outstanding issues.

54

I had two issues, one with my OIDC provider, and one resolved with iOS 12.2 :wink:

大家好，

我们刚刚遇到一个用户报告了这个问题，而且 apparently 在所有移动浏览器中都发生了。后来他们刷新页面后，问题似乎就解决了。

我们使用的是 Auth0，以下是用户的报告：

好吧，这个行为真的越来越奇怪了！我刚刚在笔记本电脑上成功登录了论坛，使用任何浏览器——Firefox、Chrome 和 Safari 都正常工作。但在我的移动设备上——没有一个能工作。无法用 Firefox、Chrome 或 Safari 登录。今天上午 9:57（EST）应该有一系列失败的请求。

每个浏览器返回的错误信息都是：“抱歉，授权您的账户时出错。也许您未批准授权？”

然后，我回到每个浏览器再次尝试登录，当我点击“登录”时，弹出的 Auth0 对话框竟然不同了。由于我几分钟前刚通过 Auth0 登录过，它识别出了我，并提示“您想再次使用 登录吗？”，我点击确认后，就成功进入了论坛！这在所有三个移动浏览器上都发生了！所以现在我已经在手机上登录了，技术上来说我的问题暂时解决了。

不过，我认为 Discourse 与 Auth0 的连接在移动设备上有点问题。在我的笔记本电脑上，Auth0 会弹出一个新窗口，而且始终能正常工作。而在移动设备上，Auth0 不会在新窗口中打开，而是当前页面直接重定向到 Auth0 再返回——这意味着移动设备上有独立的 Auth0 流程。我第一次尝试 Auth0 时，在移动设备上似乎从未成功过。但如果我再试一次，而 Auth0 已经知道我是谁，那么交接过程就能顺利完成了！

如果你们想调试这个问题，可以查看上面时间戳的日志，看看显示了哪些错误。另外，也许可以配置 Discourse/Auth0，让 Auth0 在移动设备上使用与网页端相同的流程？或者类似的方法。不过，如果只有我遇到这个问题，那可能也只是某个奇怪的 Cookie 问题！

我们确实在那个确切时间点记录到了以下错误信息：

所以对我们来说，这听起来很可能是 OmniAuth 和 Auth0 组合的一个 bug？我会尝试向 Auth0 团队反馈，看看他们是否有任何见解，因为这个问题似乎只在移动设备上由特定的 Auth0/Discourse 状态组合触发。

我还没有询问用户他们运行的 iOS 版本。

56

嗨，Simon，谢谢你的信息。

需要说明的是，在 iOS 上，所有这些浏览器本质上都是相同的。Apple 不允许使用第三方浏览器引擎，因此 Chrome 和 Firefox 只是 Safari 的换肤版本。

如果你能查到相关信息，那将很有帮助。如果版本早于 iOS 12.2，那么他们可能遇到的是早期 iOS 的已知问题。

57

是的，原来他们使用的是 12.1 版本。我会看看能否让他们升级，并确认他们是否能复现该问题。

58

能否分享一下您是如何解决提供商相关问题的？我也遇到了同样的问题和错误。
