Redirect issue with Jasig CAS and Websphere - spring-security

We currently have a set up with a load balancer carrying out SSL offloading, an http server and a websphere app server. Having got over the initial hurdle of the offloading preventing CAS from thinking it was running under https (which we got around by using the httpsIndicatorHeader variable), we now have another issue. Despite the fact we can see CAS redirecting to the target application, the 'handshake' seems to fail, showing a loop of tickets being generated and tried, but never actually validating, and the target application is never reached. There do not seem to be any errors being generated however.
Has anyone experienced anything similar before?
Cheers,
Rob

After investigation, the problem was that the application redirect url set up in websphere was pointing to the original url, rather than suffixing /j_spring_cas_security_check. This caused the circular loop to occur without any attempt to validate the ticket.

Identity Server 4 with Chrome 76 gets stuck on authorize callback

At my work, we are finally upgrading our old Identity Server 3 to 4. We just got a very weird problem doing so. Everything works fine in all major browsers, but we also need to support some Electron clients. Here is where the weird part begins. All very old clients using Electron version 3 still work. All newer clients starting at Electron 9 also work. The only clients that don't work are the ones using Electron 6 (Chrome 76).
I already found this very helpful article written by Sebastian Gingter which helped to get the login working. But it only got me one step further. Now the client gets stuck at the connect/authorize/callback endpoint using the response_mode = form_post.
I already found some articles/stackoverflow questions pointing out to check the redirect URIs and to downgrade the CSP to version 1. The redirect URIs are configured correctly since the other clients work. The CSP does not help since I don't even get that far. It seems that the response body is never even loaded by Electron/Chrome.
Devtools Timing Screenshot
The request never finishes. On the server-side, it does though. I debugged through the IS 4 code and the dynamic HTML is written to the response like with all the other clients. I even called CompleteAsync() on the response manually and it still did not finish.
I researched and debugged for quite some time now and am out of ideas. Does anyone out there know this issue and more importantly also knows how to fix it?

cname redirect causing phishing warning in heroku

I changed my CNAME Records as outlined in this link https://devcenter.heroku.com/articles/custom-domains. The redirect itself works, the issue is in Chrome (and I assume other browsers) It gives me a phishing alert.
This is probably not the site you are looking for!
You attempted to reach app.grewpr.com, but instead you actually reached a server i identifying itself as *.herokuapp.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of app.grewpr.com.
You should not proceed, especially if you have never seen this warning before for this site.
How would I fix this error? It also puts a red line through the https lock.
Since you're using HTTPS, you should follow slightly different DNS configuration instructions: https://devcenter.heroku.com/articles/ssl#configuredns
Had the same problem. Your custom domain app uses your host certificate. Whether buy SSL addon or if 'http' is ok for you then change ssl settings for your app. In "environments/production.rb" there must be following configuration "config.force_ssl = false" which by default is set to true. Had to reset Firefox to take effect. Other browsers were ok.

401 Unauthorized on ajax requests

We have recently moved our webserver to a new machine (IIS based) and in the asp.net mvc application I am working on, I have noticed that in the firebug console each request fails twice with a 401 error before finally succeeding on the 3rd try. This did not happen previously and the application seems to be running slightly slower than before, though that could just be my perception.
What might be causing this issue and what might I be able to do in order to avoid it?
I ran into a similar problem couple weeks back and the below post saved my day...
https://serverfault.com/questions/137073/401-unauthorized-on-server-2008-r2-iis-7-5
I hope this may help you...
Consider trying to check your IIS pool. Or maybe a timeout expiration?

Error 104: Connection reset by peer with ASP.NET MVC app

I'm having a problem with a MVC (1.0) app that I can't figure out at all. There's two versions of the site (live and UAT) hosted on the same server. For each version of the site, the same code is shared by multiple organisations who each have their own database (MSSQL2005) and a separate web site in IIS (7.5) (pointed to the same code).
The UAT site has an update to the code and the database that is waiting to be deployed to the live site.
One of the customers ("customer A") is getting an error "104: Connection reset by peer" when they try to log in to the UAT site. They can see the login page but when they submit their login details the connection seems to be timing out (the requests seem to take ~130s to complete).
Customer A can log in fine to the live site. The other customers don't have a problem logging into the UAT site or the live site. If I try to log in as customer A, using their login details, it all works fine from within our network, and also from outside our network.
Customer A seems to be using squid as a proxy.
I can't think what the problem could be, and I've run out of ideas of things to test. The fact that I can log in as the customer fine and other customers don't have any issues seems to eliminate the code and database as problems.
What other things could I do to try and isolate the problem?
By dumping out the request data I was able to work out that something (I'm guessing the proxy) was removing the form values from the request. This obviously meant the app didn't work properly.
However, it seems whatever was removing the form data was leaving content-length unchanged, which would explain why the client was timing out waiting for more data and the server thought it was finished.
By using https instead of http (which we were going to do anyway), the request tampering seem to have stopped.

Rails - Invalid Authenticity Token After Deploy

We're using EngineYard Cloud to deploy our Ruby on Rails application. We are running Rails v2.3.3.
EngineYard Cloud deploys to AWS instances in a manner similar to Capistrano. After each deploy, we're running into Invalid Authenticity Token errors. Specifically, any user that has previously visited our application and then visits after the deploy and then tries to submit a form gets an invalid authenticity token error. This error persists until they reset their cookies for the site. After they reset their cookies, the site works as expected with no errors.
We are using ActiveRecord's session store and sessions are being saved to the database.
This is the error we are seeing:
ActionController::InvalidAuthenticityToken
/usr/lib/ruby/gems/1.8/gems/actionpack-2.3.3/lib/action_controller/request_forgery_protection.rb:79:in `verify_authenticity_token'
The session object is nil after the deploy, however, the session data still persists in the database and the session ID cookie still exists:
Session:
session id: nil
data: nil
We haven't been able to explain this one. Any thoughts on what could be the root cause?
Thanks for any suggestions!
EDIT: Just to update on this, we've been able to isolate an example of the error.
1) User loads form
2) Code is updated on server
3) User submits form
** Invalid Authenticity Token error occurs
It seems that when the environment changes, Rails is unable to handle this with the authenticity token.
We've tried several steps to resolve:
Resetting the session
Deleting the session cookie (both in JavaScript and Rails)
Wiping the session table in the database after deploying code
Nothing works. The only thing that works is having the user clear their cookies client-side.
(We've been Googling (even tried Binging!) for answers, but no dice. This seems to be a similar related issue: http://railsforum.com/viewtopic.php?id=21479)
Also: initially we thought this was isolated to our deployment to EngineYard, but we've also been able to reproduce it on our development server that we deploy to via Capistrano.
Any thoughts would be gratefully accepted.
Thanks!
ANSWER: After extensive work by EngineYard (they're awesome!) they were able to diagnose the issue. The root cause of this issue is a bug with mongrel clusters. Mongrel doesn't seem to see the first post request after being started. EngineYard did extensive work to diagnose this:
There doesn't appear to be anything in your code causing the issue and I have found people outside of our environment that have experienced the bug as well (http://www.thought-scope.com/2009/07/mongrelcluster-rails-23x-bad-post.html). I suppose a lot of people don't see it because the first request to a site generally isn't a post or they chalk it up to flukes.
[There is a potential workaround using CURL.] The curl work around would do a simple GET request to each of your mongrels on the server to prime them so to speak. You could do this with capistrano, but that won't work if you deploy via the dashboard. You can find a short section on deploy hooks we have built into the infrastructure here:
https://cloud-support.engineyard.com/faqs/overview/getting-started-with-engine-yard-cloud
Adding a simple run curl http://localhost:500x > /dev/null should work (where x is the port you have 5000-50005 on your current setup).
We have addressed the issue by switching our stack from Mongrel to Passenger, but apparently, a fix for Mongrel is in the works. Hopefully, this helps someone who sees this same strange issue.
The authenticity token is a hidden field on the form that rails checks when the form is submitted to ensure that the post data is coming from a live session.
It is there as a security measure to prevent malicious people from using a form submit on their site to say a delete action on someones account.
You can turn it off on your whole app by adding this to config/environment.rb
config.action_controller.allow_forgery_protection = false
You can turn it off a single controller using
skip_before_filter :verify_authenticity_token
or turn it on
protect_from_forgery :except => :index
check out the ActionController::RequestForgeryProtection::ClassMethods docs for more details
It sounds like the secret key used for authentication is changing when you redeploy, invalidating all existing sessions.
Do you have the configuration parameter config.action_controller.session set anywhere, and if you do, is there anything which would cause it to change when you redeploy?
One of my apps has it configured in config/environment.rb, and a more recent one (generated with Rails 2.3) has it set in config/initializers/session_store.rb. The setting looks like:
config.action_controller.session = {
:secret => 'long-string-of-hex-digits'
}
If you don't have this configured for some reason, rake secret will generate a key for you, which can then be inserted into your configuration.
(If it is — and it's not being changed by your deployment processes — then I have no idea what's going on.)
If it would only be there for mongrels! I'm getting the exact same error on passenger as well (user loads form, deploy, submit -> invalid authenticity token). It'd be interesting to know how you solved the issue by switching to passenger? Any further hints are highly welcome. I'll have a closer look as well...
Cheers!
Have encountered this same problem with Rails 2.3 and a Mongrel cluster where the session secret is definitely set in the session initializer. The problem occured even after clearing the client cookies on the client.
However the suggestion of doing a curl get request across all the mongrels after they restart appears to work - thank goodness someone figured this out because it appears to be pretty darned obscure.
The only added info I can supply we are using Apache mod_proxy_balancer along with https in front of our Mongrels, however this problem was occuring before we turned on SSL. Is anyone seeing this with haproxy as the balancer instead of Apache?
This solved this issue for me :-) :-) :-)

August 30th, 2010 # 06:43 PM.
I've never gone to any length to figure out the details, but for me, this is a client-side data rot issue. If I've been messing around with the way I store my sessions (and therefore, my authorization details,) I get this error from time to time. Clearing out the private browser data; cookies, authenticated sessions, the works, has always solved it for me.
Hope this helps.
