csrf

In Cakephp3 when the Csrf component is enabled. How I can use it in ajax call. In this beforeSend parameter of ajax csrf token is set in header. What is the value of csrfToken . As it gives error csrfToken is not defined beforeSend: function(xhr){ xhr.setRequestHeader('X-CSRF-Token', csrfToken); }, Also how can I disable Csrf component for some ajax calls. The CSRF component writes the current token to the request parameters as _csrfToken , you can get it via the request objects param() method (or getParam() as of CakePHP 3.4): setRequestHeader('X-CSRF-Token', <?= json_encode($this->request-

在flaskWTF使用csrf保护后，一般提交form表单都需要一个隐藏的csrf 这样可以成功提交，但是使用ajax提交时就不能成功提交，会返回400错误，服务器无法理解请求，这样就需要新的方法解决ajax csrf请求问题 在网页中添加 在ajax请求上面添加 var csrftoken = $('meta[name=csrf-token]').attr('content') $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!/^(GET|HEAD|OPTIONS|TRACE)$/i.test(settings.type)) { xhr.setRequestHeader("X-CSRFToken", csrftoken) } } }) 然后再发送ajax请求就可以了 来源： https://www.cnblogs.com/vinic-xxm/p/11690070.html

I had one doubt about CSRF prevention. A lot of sites say that CSRF can be prevented by using 'tokens' which are randomly generated per session. Now my doubt is, suppose i have a function like : $.post("abcd.php",{'fbuid':userid,'code':'<?php echo md5($_SESSION['randcode']); ?>'} now this md5 hash would obviously be visible to any hacker through the source code.He could simply open this page, generate a token, and keep the page open, so that the session doesn't get destroyed, and useanother tab or anything else , to start hacking, No ? Or is my idea of tokens incorrect ? Thanks for your help

I'm creating a website using backbone and node.js and don't think that by default there is any protection against CSRF. Is there a standard way to project against CSRF when using backbone with node.js? Thanks You could simply ensure requests have the X-Requested-By header with the value XMLHTTPRequest . AJAX requests have cross-domain restrictions so if that header is present it was not e.g. a hidden form on a malicious website. I don't know of anything specific for node.js + backbone, but you can use http://www.senchalabs.org/connect/middleware-csrf.html (assuming you're using express or

The CSRF middleware and template tag provides easy-to-use protection against Cross Site Request Forgeries . This type of attack occurs when a malicious Web site contains a link, a form button or some javascript that is intended to perform some action on your Web site, using the credentials of a logged-in user who visits the malicious site in their browser. A related type of attack, ‘login CSRF’, where an attacking site tricks a user’s browser into logging into a site with someone else’s credentials, is also covered. The first defense against CSRF attacks is to ensure that GET requests (and

I have a graphql server implemented using graphene-django . I can make queries to it using jquery like this: function allIngredients() { return 'query{allProducts{edges{node{name}}}}' } var query = allIngredients(); $.ajaxSetup({ data: {csrfmiddlewaretoken: '{{ csrf_token }}' }, }); $.post("/graphql", {query: query}, function(response) { console.log(response); }) However, when I try this call with Fetch, I get a 403, because of the CORS issue. I solved the same problem in jQuery by adding ajaxSetup... before the call. Here's the call using fetch: fetch('/graphql', { method: "POST", headers: {

I have a struts2 webapp in which I need to implement CSRF protection. For statis forms it is pretty straight forward. I just need to activate the tokenSession interceptor & then set <s:token/> in the form to be submitted. (explained here and here ) But the problem appears when I need to enable CSRF protection for POST AJAX calls (I am using jQuery) which are not necessarily submitted via forms. I face the issue of re-using token when making subsequent AJAX calls. Any pointers or different approaches are appreciated. Currently I have resolved the issue by generating tokens for AJAX requests and
