Does OAuth protect against CSRF?

A system that uses OAuth2 to protect resources and delegate permissions is vulnerable to all “normal” CSRF attacks anyway - users authenticate and probably state can be changed.

Do you need CSRF with OAuth?

CSRF attack targets Cookies and Basic authentication header in general. Since in my application none of these are being used CSRF protection is not needed. Authentication starts with provided Oauth2 token (No Basic auth) and request's state is forgotten as soon as response is returned (No session cookie).

What is the best Defence against CSRF?

The most effective method of protecting against CSRF is by using anti-CSRF tokens. The developer should add such tokens to all forms that allow users to perform any state-changing operations. When an operation is submitted, the web application should then check for the presence of the correct token.

What prevents CSRF?

A key design principle that protects you from CSRF attacks is using GET requests for only view or read-only actions. These types of requests should not transform data and must only display recorded data. This limits the number of requests that are vulnerable to CSRF attacks.

What is OAuth PKCE?

PKCE OAuth OIDC. PKCE is an OAuth 2.0 security extension for public clients on mobile devices intended to avoid a malicious programme creeping into the same computer from intercepting the authorisation code. The RFC 7636 introduction discusses the mechanisms of such an attack.

Flawed CSRF Protection - State Param - Hacking Oauth Pt . 2 | Live Demo on Medium.com

Is PKCE more secure?

PKCE is better and more secure than the implicit flow (AKA the “token flow”). If you're using the implicit flow, then you should switch to PKCE. If you use an implicit flow to authorize your Dropbox app, then PKCE is a better, more secure replacement, and you should no longer use implicit flow.

Why is PKCE better than implicit?

Because web applications can't store secrets, PKCE allows for creating a secret dynamically at the beginning of the authorization flow as a contrast to the static secret in code flow (can only be used for private/server clients).

Does JWT protect against CSRF?

If you put your JWTs in a header, you don't need to worry about CSRF. You do need to worry about XSS, however. If someone can abuse XSS to steal your JWT, this person is able to impersonate you.

Is CSRF needed for REST API?

Enabling cross-site request forgery (CSRF) protection is recommended when using REST APIs with cookies for authentication. If your REST API uses the WCToken or WCTrustedToken tokens for authentication, then additional CSRF protection is not required.

Is CSRF still an issue?

Is CSRF Still Possible? Yes. Even with browsers adopting the SameSite by default policy, CSRFs are still possible under some conditions. First, if the site allows state-changing requests with the GET HTTP method, then third-party sites can attack users by creating CSRF with a GET request.

What is the #1 most commonly reported web vulnerability?

Injection is the number 1 flaw reported by OWASP. Injection can send untrusted data through SQL or other paths such as LDAP, allowing the interpreter to access unauthorized data or execute commands not intended by the application.

Does CSRF token prevent XSS?

CSRF tokens do not protect against stored XSS vulnerabilities. If a page that is protected by a CSRF token is also the output point for a stored XSS vulnerability, then that XSS vulnerability can be exploited in the usual way, and the XSS payload will execute when a user visits the page.

What is the difference between XSS and CSRF?

The key difference between those two attacks is that a CSRF attack requires an authenticated session, while XSS attacks don't. Some other differences are: Since it doesn't require any user interaction, XSS is believed to be more dangerous. CSRF is restricted to the actions victims can perform.

How does OAuth redirection work?

When should I disable CSRF?

The Spring documentation suggests: Our recommendation is to use CSRF protection for any request that could be processed by a browser by normal users. If you are only creating a service that is used by non-browser clients, you will likely want to disable CSRF protection.

How does Spring boot handle CSRF?

What is CORS and CSRF?

CSRF is a vulnerability and CORS is a method to relax the same-origin policy. CORS is something you might want to use (in certain circumstances) whereas CSRF is an undesirable design mistake. There are vulnerabilities associated with the CORS mechanism.

Is CSRF needed?

Such carefully executed Social Engineering is not always needed to perform CSRF attacks, however. In fact, every single webpage you visit can perform CSRF; surfing the Web requires a lot of trust.

How do I add CSRF token to postman?

What is the difference between CSRF and JWT?

An authentication system based on tokens (JWT or random) stored in cookies is vulnerable to CSRF attacks, because cookies are sent automatically to server in each request and an attacker could build a harmful url link to your site.

How does Spring Security prevent CSRF?

To protect MVC applications, Spring adds a CSRF token to each generated view. This token must be submitted to the server on every HTTP request that modifies state (PATCH, POST, PUT and DELETE — not GET). This protects our application against CSRF attacks since an attacker can't get this token from their own page.

Can JWT token be stolen?

What to Do if JWT Token is Stolen? There could be nothing worse than getting a JWT token stolen, as it's like providing a license to bypass all the layers of security to an attacker for exploiting sensitive information.

Is OAuth obsolete?

Important: OAuth 1.0 has been officially deprecated as of April 20, 2012. It will continue to work as per our deprecation policy, but we encourage you to migrate to OAuth 2.0 as soon as possible. .. This specification replaces and obsoletes the OAuth 1.0 protocol described in RFC 5849.

Does Google support PKCE?

Google supports the Proof Key for Code Exchange (PKCE) protocol to make the installed app flow more secure. A unique code verifier is created for every authorization request, and its transformed value, called "code_challenge", is sent to the authorization server to obtain the authorization code.

Is the OAuth 2.0 implicit flow dead?

Summary. The Implicit flow is deprecated for web applications because the Authorization Code flow with PKCE is cleaner to implement. Note that at the time of this writing, no new attacks have been discovered against the Implicit flow. It's just a relic from a different web, which we no longer need today.
