I am currently implementing Authorization_Code type OAuth2 flow to have single-sign-on (SSO) on my website.
Here is my code that enables it.
#Override
protected void configure(final HttpSecurity http) throws Exception {
// #formatter:off
http.authorizeRequests()
.antMatchers("/login", "/authorize", "/error")
.permitAll()
.anyRequest()
.authenticated()
.and().formLogin().loginPage("https://sso.mywebsite.com").loginProcessingUrl("/perform_login")
.defaultSuccessUrl("/success",true)
.failureUrl("/error").permitAll()
.and()
.csrf()
.disable();
// #formatter:on
}
My concern is described below.
To make a login request (with username and password), sso.mywebsite.com should make a POST request to my oAuth service - http://oauth/perform_login?username=USERNAME&password=PASSWORD.
I tried it with Postman and it works. However, isn't this a security problem to send plain username and password like above in query param? I thought exposing user credential in uri (query param) could get captured by various network sniffing tools.
Is there a way to do this in different method?
As long as you are using HTTPS, your query parameters will be secure.
I am unclear, why your SSO website should make a POST to that URL (and also, why instead of having a POST body, append the parameters via the url). Shouldn't it rather "redirect" to the login page/authorization server or is the code above from your authorization server? It was a bit unclear from your description.

I'm developing a back-end API of a web application (using Spring Boot). The API authenticates the users using JWT tokens. I have an endpoint for registering an account (POST /register).
Since it is a POST method, it requires a CSRF token from the front-end, and I also attach the CSRF token in the header of each response. However, when the front-end wants to call this endpoint, it needs to send a dummy register request first (which would fail) just for getting the CSRF token. My question is: Is there a better way for them to get the CSRF token? Should I create an endpoint GET /csrf just for getting the token before registering?
By the way, since I'm relatively new to security in web, I wonder if attaching the CSRF token in every response is a good practice? This is my configuration in Spring:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
.and()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.addFilter(new JwtAuthenticationFilter(authenticationManager()))
.authorizeRequests()
.antMatchers(HttpMethod.POST, "/register").permitAll()
.anyRequest().authenticated();
}
I'm trying to implement simple security for a small API school project and am a bit confused and overwhelmed. I followed
this blog post.
Everything works and I'm able to login and receive a jwt token. However login is currently performed by sending the username and password along with the URL as query parameters. That is of course something I would like to avoid.
I have tried adding httpbasic to the security configuration like this:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable()
.addFilter(new JwtAuthenticationFilter(authenticationManager(), jwtAudience, jwtIssuer, jwtSecret, jwtType))
.authorizeRequests(authorizeRequests ->
authorizeRequests
.antMatchers("/board/**").hasAnyRole("MEMBER", "BOARD")
.antMatchers("/members/**").hasRole("MEMBER")
.anyRequest().authenticated()
)
.httpbasic().and().
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
Login however ceases to work and I constantly get an unauthorized while trying basicAuth with postman.
So my question is: How can I change the behaviour of these code snippets to accept basic authentication and not send user credentials by URL? Do I have to override the AttemptAuthentication method too?
it is possible to configure spring with oauth2 to accept multiple login possibilities?
Currently I have it working with:
#Override
protected void configure(HttpSecurity http) throws Exception { // #formatter:off
http.authorizeRequests(authorizeRequests -> authorizeRequests
.anyRequest()
.authenticated())
.oauth2Login(AbstractAuthenticationFilterConfigurer::permitAll)
.addFilterAfter(new CustomAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
.logout(logout -> logout.logoutSuccessHandler(oidcLogoutSuccessHandler()))
.oauth2ResourceServer().jwt();
} // #formatter:on
If one tries to access an authorize ressource, he gets redirected to a login page of an identity provider, logs in and then get a session id on the client side. The access token and the refreh token are held into memory on the server side.
But now I also want to use an access token to access ressources.
But when I do this, the security application context is just null.
What do I have to do?
I have searching in the doc but could not understand how to achieve this.
I would expect to just add in application.properties:
spring.security.oauth2.resourceserver.jwt.jwk-set-uri
And to add:
.oauth2ResourceServer().jwt() to my HttpSecurity but this does not do the work.
Found the answer, if Bearer is not set as prefix in the Authorization header when sending the token, then it will not be recognized.
Kind of normal since it is the standard...
I am trying to develop OAuth2 Client Application with Single Sign On. I have already developed Authorization Server and tested with Client Credentials flow and its working fine. But when I try to use Authorization Code Grant with Single Sign On I could not get it right. Client application takes me to Login Screen when I access authenticated URL, but once authenticated I am redirected to call back url that's fine. But afterwards I could not access any URL as it all authenticated URL are automatically redirected to CALL BACK url. I have permitted call back url in my Security class
My requirement is once authenticated it will allow other urls normally before authentication it should not allow any url.
#Override
protected void configure(HttpSecurity http) throws Exception {
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.ALWAYS)
.and()
.authorizeRequests()
.antMatchers("/","/index.html", "/home.html", "/login**","/webjars/**", "/error**","/favicon.ico**","/oauth/token","/oauth/authorize**","/demo/1")
.permitAll()
.and()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin().permitAll()
.and()
.httpBasic();
Here the call back url is demo/1 and Spring Security is not permitting any other url here.
My requirement is once authenticated it should allow other urls normally before authentication it should not allow any url.
http.authorizeRequests().antMatchers("/","/resources/**", "/**").permitAll().anyRequest().authenticated().and().formLogin()
.loginPage("/").permitAll().usernameParameter("username").passwordParameter("password")
.loginProcessingUrl("/j_spring_security_check").failureUrl("/")
.successHandler(myAuthenticationSuccessHandler()).and().logout().logoutSuccessUrl("/")
.logoutUrl("/logout").invalidateHttpSession(true).deleteCookies("JSESSIONID").and().csrf().disable().headers().frameOptions().sameOrigin();
I have Spring Boot Rest API web app in which I am using spring security to have most endpoints to require authentication.
This is part of code:
public class SecurityConfig extends WebSecurityConfigurerAdapter {
....
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.requestMatchers()
.antMatchers("/oauth/token")
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers(HttpMethod.OPTIONS).permitAll()
.anyRequest().authenticated();
}
Can some one explain what each line begining with http.csrf means?
How can I modify above code so that enpoint /bars/pk can be allowed to be accessed without requiring authentication just as if there was no Spring Security ?
By default, Spring Boot activates protection against CSRF attack (Cross Site Request Forgery attack). The attack consists of a malicious site taking advantage of a user being alredy authenticated to a site (e.g. bank) in order to trick the user to do actions on that site (e.g. fund transfer).
The protection against the attack consists of the Spring Boot application sending a token with every response and expecting the token to be sent by the client on subsequent request. If the token is not received, Spring Boot returns an error.
Sometimes, you want to disable this behavior (at your own risks), so you use csrf.disable. You might find it convenient to disable csrf protection if you develop a Stateless API, and you have no way to link a POST request to any previous requests or session. But again, you need to consider this and reason about it carefully.
Please note that CSRF protection has not effect on GET requests. It only affects state chaning requests (e.g. POST, DELETE)
In order to allow your endoints to anyone, without requiring any authentication, you need to use
http.authorizeRequests().antMatchers("/**").permitAll();
EDIT
To specifically allow unauthorized requests to /bars/pk and keep the other elements unchanged, modify your code as follows :
http.csrf().disable()
.requestMatchers()
.antMatchers("/oauth/token")
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers(HttpMethod.OPTIONS).permitAll()
.antMatchers("/bars/pk").permitAll()
.anyRequest().authenticated();
Here is a complete example:
httpSecurity.authorizeRequests()
.antMatchers(HttpMethod.GET)
.permitAll() // Allow all GET requests to go unauthenticated
.antMatchers(allowedResources)
.permitAll() // Allow all requests to go unauthenticated for the specified paths
.antMatchers(protectedResources).hasRole(USER)
.antMatchers(adminResources).hasRole(ADMIN)
.anyRequest().authenticated(); // Authenticate all other request paths
