问题 Is it possible to configure CSRF protection in grails3 app using spring-security plugin, I can't find anything except useToken attribute for grails form and then call withForm inside controller.

Is it possible to have CSRF if developer mitigates by referrer header

阅读更多关于 Is it possible to have CSRF if developer mitigates by referrer header

问题 After pentration testing, developer mitigates the CSRF vulnerability by using only referrer header. The application have other vulnerability like XSS. Is it possible to exploit CSRF with the help of XSS? if yes how? 回答1: Short story: Its very difficult to design effective CSRF protection when XSS is present. Mitigation of CSRF via referrer header is generally considered a weak defense - there are situations where these are stripped (by the browsers or proxies) and you would need to fail these

What is the difference between XSS and CSRF from their execution perspective? https://www.quora.com/What-is-the-difference-between-XSS-and-CSRF-from-their-execution-perspective/answer/Deepthi-210 Fundamental difference is that CSRF (Cross-site Request forgery) happens in authenticated sessions when the server trusts the user/browser, while XSS (Cross-Site scripting) doesn't need an authenticated session and can be exploited when the vulnerable website doesn't do the basics of validating or escaping input. In case of XSS, when the server doesn't validate or escapes input as a primary control,

阅读更多关于 Rails Integration Testing - How to Simulate bad CSRF token and Expired Session

问题 I just changed exception handling code in my application_controller.rb to correctly capture ActionController::InvalidAuthenticityToken . I was previously doing a rescue_from Exception that was defined after the recuse_from ActionController::InvalidAuthenticityToken. This was taking priority and my intended rescue_from code was not being executed. I'd like to write an integration test to verify this behavior. How can I create an object that will allow me to send a bad CSRF token to a post

阅读更多关于 Completely disable Django's CSRF protection in SVN Trunk

问题 I've spend a few hours in frustration, trying to disable the CSRF which Django now tries to force on me, to no avail. Had anyone else tried this with more success? I'm fine with anything that works, except for a source patch (but monkeypatches are okay). 回答1: Don't do it. But if you must, try this. 回答2: I haven't actually tried to disable it (never had the need), but I imagine it's just a matter of removing the CSRF middleware(s) from the MIDDLEWARE_CLASSES setting in your settings.py. 回答3:
