Django cookie age not setting - django

I am trying to create a way for my users to have a "remember me" option when they log in. However as it stands, no matter what I try, when I view the cookie in my browser, it just shows Expires: At end of session. So once I close my browser and come back to my page, I am logged out.
In my settings.py I have set
SESSION_EXPIRE_AT_BROWSER_CLOSE = False
SESSION_COOKIE_AGE = 10000000
Which I assume are what I need to do...
On the front-end (which is in AngularJS) I have the following for the cookie storage:
$http.post('http://localhost:8000/auth/login/', {email: this.login['arguments'][0]['email'], password: this.login['arguments'][0]['password']})
.success(function(response){
if (response.token){
$cookieStore.put('djangotoken', response.token);
$http.defaults.headers.common['Authorization'] = 'Token ' + response.token;
}
})
.error(function(data, status, headers, config){
$cookieStore.remove('djangotoken');
});
If someone could show me how to get my cookies to just stay for the designated age I set that would be greatly appreciated!

You're setting the cookie directly from Angular, so it has nothing to do with the Django session cookie age. You need to pass the expiration time when you set the cookie.
Unfortunately, the built-in Angular cookieStore api is unnecessarily restrictive and does not support this. It looks like a good alternative is angular-cookie.

Django doesn't set cookie and doesn't create session

I have a problem setting cookies in Django.
Basically I have 3 different cookie I wanna set:
Session ID
Access token
Refresh token
For some reason Access and Refresh tokens are set, but the Session ID (SSID) doesn't set. If I change key of "SSID" to for example "TEST_COOKIE" it passes and I can see it in dev tools. However I need SSID and for some magical reason it doesn't work.
Here's example of my code:
class AuthResponse(SuccessResponse):
def __init__(self, data={}, ssid='', access_token: str = '', refresh_token: str = '', **kwargs):
super().__init__(data, **kwargs)
self.set_cookie(key=settings.SESSION_COOKIE_NAME,
value=ssid,)
if access_token:
self.set_cookie(key=settings.ACCESS_KEY_COOKIE_NAME,
value=access_token,)
if refresh_token:
self.set_cookie(key=settings.REFRESH_KEY_COOKIE_NAME,
value=refresh_token,)
AuthResponse inherits from SuccessResponse which is based on DjangoJsonResponse, and DjangoJsonResponse eventually inherits from HttpResponse.
So the question is - what could cause of getting rid of "SSID" cookie?
I tried to look around and find if all the data appears in init function and apprently eveyrthing is fine. All data, ssid, access_token and refresh_token come through, but only "SSID" doesn't get set.
As well I tried to use "httponly" and "secure" while setting cookies, but it didn't help.
There was an idea that might be middleware affects somehow on this, however I don't know who to check this out...
Is there anyone familiar with this who can potentially make an advice of why is this happening?
I found the answer while working on localhost the SESSION_COOKIE_DOMAIN should not be used, so I made it in this way in settings.py:
if website_settings.current_instance != 'dev':
SESSION_COOKIE_DOMAIN = (
website_settings.session_cookie_domain
if website_settings.session_cookie_domain
else f".{SITE_DOMAIN}"
)
This way it saves all needed cookies and browser sees them.

TYPO3 how to set custom cookie inside a form finisher

typo3 9.5.8
we are implementing a newsletter subscription flow with multiple steps, on submit of the second step we query graphQL in a finisher to see if the Email is valid to subscribe or not - and we set a cookie with the "state" of the email address.
setcookie("isEmailSubscribable", ($content->data->isEmailSubscribable) ? "1" : "0", time() - 3600, "/", "x.at", false);
we have to display a message on the third step based on that "state" written into a cookie. but no matter what i try the cookie does not get set (i guess).
whats the deal with cookies and typo3? is it to late to set a cookie inside a form finisher? but if yes how could i solve this?
help is much appreciated
Inside the Finisher:
// Set a cookie
$this->getTypoScriptFrontendController()->fe_user->setKey('ses', 'value', 'test');
// Get the cookie
$this->getTypoScriptFrontendController()->fe_user->getKey('ses', 'test');
ses are Session cookies
user This cookies require a fe_user to be logged in
Value can be an array, it will be stored serialized in the Database fe_sessions.ses_data
UPDATE:
Or you can try it with an PSR-15 Middleware: https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/RequestHandling/Index.html
In your Middleware Class you get a $request and $response and use them to set or read a cookie:
// Write a cookie
$response = $response->withAddedHeader(
'Set-Cookie',
$cookieName . '=' . $yourValue . '; Path=/; Max-Age=' . (time()+60*60*24*30)
);
// Read a cookie
$request->getCookieParams()[$cookieName];
You just have to check request for email address and maybe an hidden field to detect that your for was submitted.

Headless Chrome Puppeteer Skip Logging In To Twitter Using Cookies?

Is it possible to skip logging in to twitter by setting cookies?
I tried to copy an paste what I got from "document.cookie" in web console but that gave me the error Invalid parameters name: string value expected
await page.setCookie({
personalization_id: "v1_VDBAhQo+RMCSceKUBXfs3w==",
guest_id: "v1%3A150575165219105300",

_gid: "GA1.2.1311587009.1505751657"
})
The correct syntax for setCookie is not what you used, it's:
setCookie(cookie1, cookie2, ...)
where cookie is an object containing name and value keys, like
setCookie({name: 'lang', value: 'en'})
Remember to set the cookies before loading Twitter, or to reload the page after setting them, and everything should work.
async function addCookies(cookies_str, page, domain){
let cookies = cookies_str.split(';').map(pair=>{
let name = pair.trim().slice(0,pair.trim().indexOf('='))
let value = pair.trim().slice(pair.trim().indexOf('=')+1)
return {name,value,domain}
});
await Promise.all(cookies.map((pair)=>{
return page.setCookie(pair);
}))
}
this is my way to add cookies, cookies_str was copied from browser;

django: csrftoken COOKIE vs. csrfmiddlewaretoken HTML Form value

Trying to learn about security. Curious about why in django when
submitting a form (a POST), there are 2 separate "elements" that
contain the same csrf token value:
- the csrftoken cookie:
COOKIES:{'csrftoken': '1effe96056e91a8f58461ad56c0d4ddc', ...
- the Form's hidden csrfmiddlewaretoken:
POST:<QueryDict: {u'csrfmiddlewaretoken':
[u'1effe96056e91a8f58461ad56c0d4ddc'], ...
If django is inserting the hidden csrf field/value to
the form when it sends it to the browser (GET), and expects the
same value back when receiving the POST, then why is it
necessary to also set a cookie?
A more general question, if either of them was missing (form, cookie),
could you provide a scenario that explains how this could be exploited
(security attack)?
By the way, I ran a couple of simple tests to make sure that
django was checking the validity of each one separately and
indeed it is:
if I change the form's csrf value before doing the POST,
I get this debug error back:
CSRF token missing or incorrect
if I delete the csrf cookie before doing the POST,
I get a different error back:
CSRF cookie not set.
I'm just familiar with basic csrf concepts and want to
learn how django helps protect against these types of attacks.
Thanks,
jd
update:
Although both answers (S.Lott and M. DeSimone) were informative and
make sense, I thought that there could be a more detailed explanation
for requiring the presence of the security value in both the form and
in the cookie. While searching outside stackoverflow.com, I came across
a blog post from...Jeff Atwood.
I have included a third answer (sorry to answer my own question but
I think that it is relevant supplemental info) that refers to a blog
post from Jeff and includes a quotation.
From Jeff Atwood's blog entry:
Preventing CSRF and XSRF Attacks
(Oct 14, 2008)
The original post
The Felten and Zeller paper (pdf) recommends the "double-submitted
cookie" method to prevent XSRF:
When a user visits a site, the site should generate a
(cryptographically strong) pseudorandom value and set it as a
cookie on the user's machine. The site should require every form
submission to include this pseudorandom value as a form value and
also as a cookie value. When a POST request is sent to the site,
the request should only be considered valid if the form value and
the cookie value are the same. When an attacker submits a form on
behalf of a user, he can only modify the values of the form. An
attacker cannot read any data sent from the server or modify cookie
values, per the same-origin policy. This means that while an
attacker can send any value he wants with the form, he will be
unable to modify or read the value stored in the cookie. Since the
cookie value and the form value must be the same, the attacker will
be unable to successfully submit a form unless he is able to guess
the pseudorandom value.
The advantage of this approach is that it requires no server state;
you simply set the cookie value once, then every HTTP POST checks to
ensure that one of the submitted values contains the exact
same cookie value. Any difference between the two means a possible
XSRF attack.
The cookie is there for AJAX support. Quoting the Django docs:
While the above method can be used for AJAX POST requests, it has some inconveniences: you have to remember to pass the CSRF token in as POST data with every POST request. For this reason, there is an alternative method: on each XMLHttpRequest, set a custom X-CSRFToken header to the value of the CSRF token. This is often easier, because many javascript frameworks provide hooks that allow headers to be set on every request. In jQuery, you can use the ajaxSend event as follows:
$('html').ajaxSend(function(event, xhr, settings) {
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
// Only send the token to relative URLs i.e. locally.
xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
}
});
Adding this to a javascript file that is included on your site will ensure that AJAX POST requests that are made via jQuery will not be caught by the CSRF protection.
They spot two different problems.
Cookie is to authenticate the client machine making the connection.
The hidden form field is to authenticate the source of the form.
Example Scenario: User A, on the client machine could bookmark the form. User B logs on, gets a valid cookie from today. User A could submit the invalid form field from yesterday when the browser has a left-over cookie from user B's session.
what client/browser resources are typically compromised,
None.
and how is it that these csrf fields help protect us from the forgery requests?
The CSRF tokens establish identity.
One (and only one) browser has a CSRF cookie token. But that browser could have multiple copies of a site open or bookmarked forms.
One (and only one) page form on that browser has a CSRF form token.
The browser and form cookies must match to assure one browser/one form.

Cross-Domain Cookies

I have two webapps WebApp1 and WebApp2 in two different domains.
I am setting a cookie in WebApp1 in the HttpResponse.
How to read the same cookie from HttpRequest in WebApp2?
I know it sounds weird because cookies are specific to a given domain, and we can't access them from different domains; I've however heard of CROSS-DOMAIN cookies which can be shared across multiple webapps. How to implement this requirement using CROSS-DOMAIN cookies?
Note: I am trying this with J2EE webapps
Yes, it is absolutely possible to get the cookie from domain1.example by domain2.example. I had the same problem for a social plugin of my social network, and after a day of research I found the solution.
First, on the server side you need to have the following headers:
header("Access-Control-Allow-Origin: http://origin.domain:port");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Methods: GET, POST");
header("Access-Control-Allow-Headers: Content-Type, *");
Within the PHP-file you can use $_COOKIE[name]
Second, on the client side:
Within your AJAX request you need to include 2 parameters
crossDomain: true
xhrFields: { withCredentials: true }
Example:
type: "get",
url: link,
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
}
As other people say, you cannot share cookies, but you could do something like this:
centralize all cookies in a single domain, let's say cookiemaker.example
when the user makes a request to example.com you redirect him to cookiemaker.example
cookiemaker.example redirects him back to example.com with the information you need
Of course, it's not completely secure, and you have to create some kind of internal protocol between your apps to do that.
Lastly, it would be very annoying for the user if you do something like that in every request, but not if it's just the first.
But I think there is no other way.
As far as I know, cookies are limited by the "same origin" policy. However, with CORS you can receive and use the "Server B" cookies to establish a persistent session from "Server A" on "Server B".
Although, this requires some headers on "Server B":
Access-Control-Allow-Origin: http://server-a.example.com
Access-Control-Allow-Credentials: true
And you will need to send the flag "withCredentials" on all the "Server A" requests (ex: xhr.withCredentials = true;)
You can read about it here:
http://www.html5rocks.com/en/tutorials/cors/
https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS
There's no such thing as cross domain cookies. You could share a cookie between foo.example.com and bar.example.com but never between example.com and example2.com and that's for security reasons.
The smartest solution is to follow facebook's path on this. How does facebook know who you are when you visit any domain? It's actually very simple:
The Like button actually allows Facebook to track all visitors of the external site, no matter if they click it or not. Facebook can do that because they use an iframe to display the button. An iframe is something like an embedded browser window within a page. The difference between using an iframe and a simple image for the button is that the iframe contains a complete web page – from Facebook. There is not much going on on this page, except for the button and the information about how many people have liked the current page.
So when you see a like button on cnn.com, you are actually visiting a Facebook page at the same time. That allows Facebook to read a cookie on your computer, which it has created the last time you’ve logged in to Facebook.
A fundamental security rule in every browser is that only the website that has created a cookie can read it later on. And that is the advantage of the iframe: it allows Facebook to read your Facebook-cookie even when you are visiting a different website. That’s how they recognize you on cnn.com and display your friends there.

Cross-domain cookies are not allowed (i.e. site A cannot set a cookie on site B).
But once a cookie is set by site A, you can send that cookie even in requests from site B to site A (i.e. cross-domain requests):
XMLHttpRequest from a different domain cannot set cookie values for their own domain unless withCredentials is set to true before making the request. The third-party cookies obtained by setting withCredentials to true will still honor same-origin policy and hence can not be accessed by the requesting script through document.cookie or from response headers.
Make sure to do these things:
When setting the cookie in a response
The Set-Cookie response header includes SameSite=None if the requests are cross-site (note a request from www.example.dev to static.example.dev is actually a same-site request, and can use SameSite=Strict)
The Set-Cookie response header should include the Secure attribute if served over HTTPS; as seen here and here
When sending/receiving the cookie:
The request is made with withCredentials: true, as mentioned in other answers here and here, including the original request whose response sets the cookie set in the first place
For the fetch API, this attribute is credentials: 'include', vs withCredentials: true
For jQuery's ajax method, note you may need to supply argument crossDomain: true
The server response includes cross-origin headers like Access-Control-Allow-Origin, Access-Control-Allow-Credentials, Access-Control-Allow-Headers, and Access-Control-Allow-Methods
As #nabrown points out: "Note that the "Access-Control-Allow-Origin" cannot be the wildcard (*) value if you use the withCredentials: true" (see #nabrown's comment which explains one workaround for this.
In general:
Your browser hasn't disabled 3rd-party cookies. (* see below)
Things that you don't need (just use the above):
domain attribute in the Set-Cookie; you can choose a root domain (i.e. a.example.com can set a cookie with a domain value of example.com, but it's not necessary; the cookie will still be sent to a.example.com, even if sent from b.other-site.example
For the cookie to be visible in Chrome Dev Tools, "Application" tab; if the value of cookie HttpOnly attribute is true, Chrome won't show you the cookie value in the Application tab (it should show the cookie value when set in the initial request, and sent in subsequent responses where withCredentials: true)
Notice the difference between "path" and "site" for Cookie purposes. "path" is not security-related; "site" is security-related:
path
Servers can set a Path attribute in the Set-Cookie, but it doesn't seem security related:
Note that path was intended for performance, not security. Web pages having the same origin still can access cookie via document.cookie even though the paths are mismatched.
site
The SameSite attribute, according to example.dev article, can restrict or allow cross-site cookies; but what is a "site"?
It's helpful to understand exactly what 'site' means here. The site is the combination of the domain suffix and the part of the domain just before it. For example, the www.example.dev domain is part of the example.dev site...
This means a request to static.example.dev from www.example.dev, is a sameSite request (the only difference in the URLs is in the subdomains).
The public suffix list defines this, so
it's not just top-level domains like .com but also includes services
like github.io
This means a request to your-project.github.io from my-project.github.io, is a a cross-site request (these URLs are at different domains, because github.io is the domain suffix; the domains your-project vs my-project are different; hence different sites)
This means what's to the left of the public suffix; is the subdomain (but the subdomain is a part of the host; see the BONUS reply in this answer)
www is the subdomain in www.example.dev; same site as static.example.dev
your-project is the domain in your-project.github.io; separate site as my-project.github.io
In this URL https://www.example.com:8888/examples/index.html, remember these parts:
the "protocol": https://
the "scheme": https
the "port": 8888
the "domain name" aka location.hostname: www.example.com
the "domain suffix" aka "top-level domain" (TLD): com
the "domain": example
the "subdomain": www (the subdomain could be single-level (like www) or multi-level (like foo.bar in foo.bar.example.com)
the "site" (as in "cross-site" if another URL had a different "site" value): example.com
"site" = "domain" + "domain suffix" = example.com
the "path": /examples/index.html

(Be careful; I was testing my feature in Chrome Incognito tab; according to my chrome://settings/cookies; my settings were "Block third party cookies in Incognito", so I can't test Cross-site cookies in Incognito.)
You cannot share cookies across domains. You can however allow all subdomains to have access. To allow all subdomains of example.com to have access, set the domain to .example.com.
It's not possible giving other.example access to example.com's cookies though.
Do what Google is doing. Create a PHP file that sets the cookie on all 3 domains. Then on the domain where the theme is going to set, create a HTML file that would load the PHP file that sets cookie on the other 2 domains. Example:
<html>
<head></head>
<body>
<p>Please wait.....</p>
<img src="http://domain2.example/setcookie.php?theme=whateveryourthemehere" />
<img src="http://domain3.example/setcookie.php?theme=whateveryourthemehere" />
</body>
</html>
Then add an onload callback on body tag. The document will only load when the images completely load that is when cookies are set on the other 2 domains. Onload Callback:
<head>
<script>
function loadComplete(){
window.location="http://domain1.example";//URL of domain1
}
</script>
</head>
<body onload="loadComplete()">
setcookie.php
We set the cookies on the other domains using a PHP file like this:
<?php
if(isset($_GET['theme'])){
setcookie("theme", $_GET['theme'], time()+3600);
}
?>
Now cookies are set on the three domains.
You can attempt to push the cookie val to another domain using an image tag.
Your mileage may vary when trying to do this because some browsers require you to have a proper P3P Policy on the WebApp2 domain or the browser will reject the cookie.
If you look at plus.google.com p3p policy you will see that their policy is:
CP="This is not a P3P policy! See http://www.google.com/support/accounts/bin/answer.py?hl=en&answer=151657 for more info."
that is the policy they use for their +1 buttons to these cross domain requests.
Another warning is that if you are on https make sure that the image tag is pointing to an https address also otherwise the cookies will not set.
There's a decent overview of how Facebook does it here on nfriedly.com
There's also Browser Fingerprinting, which is not the same as a cookie, but serves a like purpose in that it helps you identify a user with a fair degree of certainty. There's a post here on Stack Overflow that references upon one method of fingerprinting
I've created an NPM module, which allows you to share locally-stored data across domains:
https://www.npmjs.com/package/cookie-toss
By using an iframe hosted on Domain A, you can store all of your user data on Domain A, and reference that data by posting requests to the Domain A iframe.
Thus, Domains B, C, etc. can inject the iframe and post requests to it to store and access the desired data. Domain A becomes the hub for all shared data.
With a domain whitelist inside of Domain A, you can ensure only your dependent sites can access the data on Domain A.
The trick is to have the code inside of the iframe on Domain A which is able to recognize which data is being requested. The README in the above NPM module goes more in depth into the procedure.
Hope this helps!
Since it is difficult to do 3rd party cookies and also some browsers won't allow that.
You can try storing them in HTML5 local storage and then sending them with every request from your front end app.
One can use invisible iframes to get the cookies. Let's say there are two domains, a.example and b.example. For the index.html of domain a.example one can add (notice height=0 width=0):
<iframe height="0" id="iframe" src="http://b.example" width="0"></iframe>
That way your website will get b.example cookies assuming that http://b.example sets the cookies.
The next thing would be manipulating the site inside the iframe through JavaScript. The operations inside iframe may become a challenge if one doesn't own the second domain. But in case of having access to both domains referring the right web page at the src of iframe should give the cookies one would like to get.
Along with #Ludovic(approved answer) answers we need to check one more option when getting set-cookies header,
set-cookie: SESSIONID=60B2E91C53B976B444144063; Path=/dev/api/abc; HttpOnly
Check for Path attribute value also. This should be the same as your API starting context path like below
https://www.example.com/dev/api/abc/v1/users/123
or use below value when not sure about context path
Path=/;

local storage
cookie storage
Secure cookies - are used by encrypted websites to offer protection from any possible threats from a hacker.
access cookie - document.cookie. This means that this cookie is exposed and can be exploited through cross-site scripting. The saved cookie values can be seen through the browser console.
As a precaution, you should always try to make your cookies inaccessible on the client-side using JavaScript.
HTTPonly - ensures that a cookie is not accessible using the JavaScript code. This is the most crucial form of protection against cross-scripting attacks.
A secure attribute - ensures that the browser will reject cookies unless the connection happens over HTTPS.
sameSite attribute improves cookie security and avoids privacy leaks.
sameSite=Lax - It is set to Lax (sameSite = Lax) meaning a cookie is only set when the domain in the URL of the browser matches the domain of the cookie, thus eliminating third party’s domains. This will restrict cross-site sharing even between different domains that the same publisher owns. we need to include SameSite=None to avoid the new default of Lax:
Note: There is a draft spec that requires that the Secure attribute be set to true when the SameSite attribute has been set to 'none'. Some web browsers or other clients may be adopting this specification.
Using includes as { withCredentials: true } must include all the cookies with the request from the front end.
const data = { email: 'youremailaddress#gmail.com' , password: '1234' };
const response = await axios.post('www.yourapi.com/login', data , { withCredentials: true });
Cookie should only be accepted over a secure HTTPS connection. In order to get this to work, we must move the web application to HTTPS.
In express.js
res.cookie('token', token, {
maxAge: 1000 * 60 * 60 * 24, // would expire after (for 15 minutes 1000 * 60 * 15 ) 15 minutes
httpOnly: true, // The cookie only accessible by the web server
sameSite: 'none',
secure: true, // Marks the cookie to be used with HTTPS only.
});

Read Cookie in Web Api
var cookie = actionContext.Request.Headers.GetCookies("newhbsslv1");
Logger.Log("Cookie " + cookie, LoggerLevel.Info);
Logger.Log("Cookie count " + cookie.Count, LoggerLevel.Info);
if (cookie != null && cookie.Count > 0)
{
Logger.Log("Befor For " , LoggerLevel.Info);
foreach (var perCookie in cookie[0].Cookies)
{
Logger.Log("perCookie " + perCookie, LoggerLevel.Info);
if (perCookie.Name == "newhbsslv1")
{
strToken = perCookie.Value;
}
}
}
