Please try to resubmit the form So I go over to one of my other forms that has the same type of information, and check the _token out

How to best prevent CSRF attacks in a GAE app?

阅读更多关于 How to best prevent CSRF attacks in a GAE app?

问题 So, what is the best way to prevent an XSRF attack for a GAE application? Imagine the following: Anyone can see a user's public object, and the db.Model id is used in the request to figure out which object to show. Malicious user now has the id. Malicious user creates their own object and checks out the delete form. They now know how to delete an object with a certain id. Malicious user gets innocent user to submit a delete request for that user's object. What steps can I add to prevent #3?

AngularJS index.html <head> <meta name="_csrf" content="${_csrf.token}"/>  <meta name="_csrf_header" content="${_csrf.headerName}"/> </head> SpringSecurity 3.2 Spring uses HttpSessionCsrfTokenRepository which by default gives header name for CSRF as X-CSRF-TOKEN , however Anuglar convention is X-XSRF-TOKEN I wanted to extend HttpSessionCsrfTokenRepository and override the header name, but since it is marked final I ended up implementing a custom token repository. @Component public class CustomCsrfTokenRepository implements CsrfTokenRepository {

Unique form token disables multitasking for the user

阅读更多关于 Unique form token disables multitasking for the user

If I want to protect my site and users from Cross Site Forgery (CSRF) attacks, I can generate a unique token $token = md5( time() * rand ); on every page that has a form. The token is is submitted in a hidden input field echo '<input type="hidden" name="token" value="'.$token.'">'; and at the same time stored in a session variable $_SESSION['token'] = $token; . I will check if on any submitted form if($_POST['token'] == $_SESSION['token']) and proceed accordingly. However some users may multitask. Which is something that I am actually doing right now, while I am posting this. While composing

阅读更多关于 ASP.NET MVC Anti Forgery Token Insecure

问题 I can actually see the verification token key generated by MVC3 framework in plain text when making a request to the server without ssl. This key is stored in a cookie called: _RequestVerificationToken_Lw__ In mixed security environment it is actually possible to see this token in plain text sent to the server on the initial request to the non ssl site. This token is also static for the duration of the user's session. Then what's the use of having this token when it can easily be stolen by an

How to fetch and reuse the CSRF token using Postman Rest Client

阅读更多关于 How to fetch and reuse the CSRF token using Postman Rest Client

I am using Postman Rest client for hitting the rest services. I am getting the following error when I try to execute the rest service from Postman client. HTTP Status 403 - Cross-site request forgery verification failed. Request aborted. It appears that the rest services are secured by the implementation of CSRF token. Does anybody has any idea about how to fetch the CSRF token and reuse it for future requests? Gabor Lengyel There are several ways to protect against CSRF in an application. Depending on which type of protection your services have, you will have to do slightly different things,

Please try to resubmit the form. After surfing on the Internet and reducing the code to almost empty. I still get that error. Most of the people who I've seen asking for that solved the error using the following twig code {{ form_rest(form) }} The problem is that I'm using it, it's like when I bind the request it doesn't do it correctly. I don't know what else can I do. This is my small twig template:

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 由翻译强力驱动问题: My current setup is AngularJS + Django 1.5 and I have completely thrown away the use of Django's template engine (ie. the backend is pretty much an API server). Since I am not using the csrf_token template tag, Django, in turn, does not set and send the csrftoken cookie in response. As instructed by the official docs, the ensure_csrf_cookie() decorator should be used to force the decorated view to send the csrftoken cookie. I have applied the ensure_csrf_cookie() decorator to the view, which serves the first GET request that my web

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I've read several posts about csrf protection in Django, including Django's documentation , but I'm still quite confused in how to use it correctly. The clearest part is the HTML one, but the Python's one is kinda confusing. HTML {% csrf_token %} inside the form Python c = {} c.update(csrf(request)) You need it in every form when displaying and requesting the information, don't you? Then, how do you include this csrf protection in the return render() ? Is this correct? return render(request,'index.html',{'var':var_value}) or should I include
