How to use Zend Framework Form Hash (token) with AJAX

阅读更多关于 How to use Zend Framework Form Hash (token) with AJAX

问题 I have included Zend_Form_Element_Hash into a form multiplecheckbox form. I have jQuery set to fire off an AJAX request when a checkbox is clicked, I pass the token with this AJAX request. The first AJAX request works great, but the subsequent ones fail. I suspect it may be once the token has been validated it is then removed from the session (hop = 1). What would be your plan of attack for securing a form with Zend Framework Hash yet using AJAX to complete some of these requests? 回答1: I

问题 I'm having issues with CSRF tokens. When I submit a form, a new XSRF-TOKEN is being generated but I think I'm generating two different tokens, I'm kinda confused. There's also a token called _csrf , so I see two different cookies in developer tools (XSRF-TOKEN and _csrf), _csrf doesn't change after a post. What I want to do is to generate a new token for each post request and check whether it's valid or not. One thing I know that I should do it for security, but I stuck. It has been a long

阅读更多关于 Laravel 4: Prevent multiple form submissions - CSRF Token

问题 Problem scenario: I'm creating a blog with Laravel 4. The form that's responsible for the creation of new blog posts is secured by the build in CSRF protection (Laravel Docs: CSRF Protection).

The problem that occurs is that if the user hits the back button of the browser to return to the submitted form, the entered data persists and the user is able to "re-submit" the form. This might

利用登录授权窃取你的令牌

在2018年年中，Linode的Hackerone漏洞悬赏项目吸引了我，因为这个项目很活跃，管理得非常好，但很多漏洞细节并没有公开。我希望能找到漏洞，并对外公开某个漏洞细节。 Linode是一个VPS提供商，而用户购买的VPS将解析为 <id>.members.linode.com ，而这也给了我灵感，因为这基本上意味着我们能完全控制 linode.com 的子域，执行任何服务端脚本语言。了解Linode的身份认证 Linode主要对外提供了4个Web应用： https://manager.linode.com 经典Linode网站 https://linode.com/community 社区门户 https://login.linode.com OAuth服务器 https://cloud.linode.com 新型Linode网站当我们完全控制子域时，可以读取任何和 .linode.com （cookie被设置为通配符域）有关的cookie，我开始研究 [https://manager.linode.com](https://manager.linode.com) 中的session/CSRF的cookie，但所有cookie都正确地设置为only manager.linode.com ，然后我转移到另一个应用 [https://linode.com/community]

Why Same-origin policy isn't enough to prevent CSRF attacks?

阅读更多关于 Why Same-origin policy isn't enough to prevent CSRF attacks?

问题 First of all, I assume a backend that control inputs to prevent XSS vulnerabilities. In this answer @Les Hazlewood explain how to protect the JWT in the client side. Assuming 100% TLS for all communication - both during and at all times after login - authenticating with username/password via basic authentication and receiving a JWT in exchange is a valid use case. This is almost exactly how one of OAuth 2's flows ('password grant') works. [...] You just set the Authorization header:

CSRF token missing or invalid Django

问题 I've run into this issue before and solved it, but this just popped up totally randomly (or so it seems). I've just come back to my Django project after a little while away from it...when logging in I forgot my web username and it gave me the appropriate error message Sorry, that's not a valid username or password . So to solve this I created a new superuser (since I had also forgot my admin username) so I could check what my web username was. I did that successfully, but now when I try to
