Enabling Spring Security makes Swagger output text/plain instead of HTML - spring-security

Swagger works! I can interact with http://localhost:8090/sdoc.jsp and everything is fine.
I add the following to pom.xml...
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
I also add the following two files:
#Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
#Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
String name = authentication.getName();
String password = authentication.getCredentials().toString();
if( !Authenticate.authenticate(name, password) )
return null;
List<GrantedAuthority> grantedAuths = new ArrayList<>();
grantedAuths.add(new SimpleGrantedAuthority("ROLE_USER"));
Authentication auth = new UsernamePasswordAuthenticationToken(name, password, grantedAuths);
return auth;
}
#Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
and
#Configuration
#EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.disable()
.authorizeRequests()
.anyRequest().permitAll()
.antMatchers("/**").authenticated().and()
.formLogin().loginPage("/login").permitAll().and()
.httpBasic()
;
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(new CustomAuthenticationProvider());
}
}
At this point if I visit the same URL that was previously working I now instead get a response type of "text/plain" and instead of a pretty HTML looking browser I see source code.
If I revert the change and remove the two files from project and remove JAR file it works again.
How do I get Spring Security and Swagger to play nice? What am I doing wrong.

I suspect this is due to Spring-Security's effect on the content-type headers (http://docs.spring.io/spring-security/site/docs/3.2.0.CI-SNAPSHOT/reference/html/headers.html#headers-content-type-options).
From the docs -
Historically browsers, including Internet Explorer, would try to guess the content type of a request using content sniffing. This allowed browsers to improve the user experience by guessing the content type on resources that had not specified the content type. For example, if a browser encountered a JavaScript file that did not have the content type specified, it would be able to guess the content type and then execute it.
The problem with content sniffing is that this allowed malicious users to use polyglots (i.e. a file that is valid as multiple content types) to execute XSS attacks. For example, some sites may allow users to submit a valid postscript document to a website and view it. A malicious user might create a postscript document that is also a valid JavaScript file and execute a XSS attack with it.
Again, from the docs, in order to override the default -
#EnableWebSecurity
#Configuration
public class WebSecurityConfig extends
WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
// ...
.headers()
.contentTypeOptions();
}
}

Wow, I figured it was something along these lines. Thanks so much
When I tried this and it started working
.headers()
.disable()
I narrowed the default contentTypeOptions down to..
.headers()
//.contentTypeOptions() // If this is uncommented it fails.
.xssProtection()
.cacheControl()
.httpStrictTransportSecurity()
.frameOptions()
.and()

How to properly configure spring-security with vaadin14 to handle 2 entry points - keyclaok and DB

I have a vaadin14 application that I want to enable different types of authentication mechanisms on different url paths. One is a test url, where authentication should use DB, and the other is the production url that uses keycloak.
I was able to get each authentication mechanism to work separately, but once I try to put both, I get unexpected results.
In both cases, I get login page, but the authentication doesn't work correctly. Here's my security configuration, what am I doing wrong?
#Configuration
#EnableWebSecurity
public class ApplicationSecurityConfiguration {
#Configuration

.requestCache().requestCache(new CustomRequestCache())
// Restrict access to our application.
.and().antMatcher("/test**").authorizeRequests()

Navigating within a Vaadin UI will change the URL in your browser, but it will not necessarily create a browser request to that exact URL, effectively bypassing the access control defined by Spring security for that URL. As such, Vaadin is really not suited for the request URL-based security approach that Spring provides. For this issue alone you could take a look at my add-on Spring Boot Security for Vaadin which I specifically created to close the gap between Spring security and Vaadin.
But while creating two distinct Spring security contexts based on the URL is fairly easy, this - for the same reason - will not work well or at all with Vaadin. And that's something even my add-on couldn't help with.
Update: As combining both security contexts is an option for you, I can offer the following solution (using my add-on):
Starting from the Keycloak example, you would have to do the following:
Change WebSecurityConfig to also add your DB-based AuthenticationProvider. Adding your UserDetailsService should still be enough. Make sure to give every user a suitable role.
You have to remove this line from application.properties: codecamp.vaadin.security.standard-auth.enabled = false
This will re-enable the standard login without Keycloak via a Vaadin view.
Adapt the KeycloakRouteAccessDeniedHandler to ignore all test views that shouldn't be protected by Keycloak.
I already prepared all this in Gitlab repo and removed everything not important for the main point of this solution. See the individual commits and their diffs to also help focus in on the important bits.

Spring Boot Security Configuration OAuthSSO and ResourceServer

I have a WebApp consisting of 2 parts.
One is with a frontend (Vaadin) where i want the user to be Logged-In via OAuth2. I then Check whether the user has a certain Role or not. --> If user opens the URL he shall be redirected to the OAuthLogin automatically. --> This is working with the #EnableOAuthSso.
Second Part is the REST-API of the Application, which is found by anything under /api/*. fE. /api/devices
should give me a list if the Get-Request has a valid Bearer-Token. If the GET Request has no Bearer-Token or a wrong Role (Authority) if want to get a 403.
Now this is my configuration:
#Configuration
#EnableOAuth2Sso
public class ProdWebSecurityConfiguration extends WebSecurityConfigurerAdapter {
private static final String ADMIN_ROLE= "role.global.admin";
private static final String READ_API_ROLE= "role.base.read.api";
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
http.authorizeRequests()
.antMatchers("/login**", "/error**").permitAll()
.antMatchers("/*").hasAuthority(ADMIN_ROLE)
.antMatchers("/api/**").hasAnyAuthority(ADMIN_ROLE, READ_API_ROLE)
.and().logout().permitAll().logoutSuccessUrl(rootAuthUri + "/connect/endsession")
;
}
Now when opening for example /manageDevices in the Browser i get forced to be logged in via Auth-Code-Flow and everything works like as expected.
When i try to open /api/devices i also get forced to be logged in via Oauth. Even when i do send Http-Header with Authentication: Bearer xxxxx. Somehow it always forces me to the Login-Screen from my OAuth login.
application.properties these lines are defined:
base.rootauthuri=https://oauth2.mypage.ch
security.oauth2.client.clientId=client.base.parameters
security.oauth2.client.clientSecret=secret
security.oauth2.client.accessTokenUri=${base.rootauthuri}/connect/token
security.oauth2.client.userAuthorizationUri=${base.rootauthuri}/connect/authorize
security.oauth2.client.scope=openid,scope.base.parameters,role,offline_access
security.oauth2.client.clientAuthenticationScheme=form
security.oauth2.resource.userInfoUri=${base.rootauthuri}/connect/userinfo
How can i force everything under /api/* to not redirect to the AuthenticationForm but respond with 403 if no Bearer Token is sent. How can i make it to Check whether the Bearer-Token has Role "READ_API_ROLE" also.
I had the same question with SSO, I configured a ResourceServe for that:
#Configuration
#EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
#Autowired
private ResourceServerConfiguration configuration;
#PostConstruct
public void setSecurityConfigurerOrder() {
configuration.setOrder(3);
}
#Bean("resourceServerRequestMatcher")
public RequestMatcher resources() {
return new AntPathRequestMatcher("/api/**");
}
#Override
public void configure(HttpSecurity http) throws Exception {
http
.requestMatchers().antMatchers("/v1/**") // this is free resource
.and().authorizeRequests()
.antMatchers("/api/**").permitAll() // This is free resource for mvc calls
// Usado para paths que necessitam de token bearer
.and().requestMatchers().antMatchers("/integration/**")
.and().authorizeRequests()
.antMatchers("/integration/**").authenticated(); // this is protected resource, it's necessary token
}
}
I not configure WebSecurityConfigurerAdapter in my project;
Check this:
Spring Boot 1.3.3 #EnableResourceServer and #EnableOAuth2Sso at the same time
https://www.baeldung.com/spring-security-oauth2-enable-resource-server-vs-enable-oauth2-sso

where i should properly store first password

I have a question about storing "base" password for spring security app. I read documentation and IMHO i should have first pass stored somewhere hardcoded. Is that right or how i should be done?
As example i've post defauld helloWorld code from spring security.
#Configuration
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
#Bean
#Override
public UserDetailsService userDetailsService() {
PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
String s = encoder.encode("password");
UserDetails user = User.withUsername("userName")
.password(s)
.roles("USER")
.build();
return new InMemoryUserDetailsManager(user);
}
}
You have several options.
Hardcode it.
Store username/pass in a .property file. This gives you more flexibility, and also an ability to disable the user (e.g. set the name to empty and skipping it in the code)
Generate password via existing PasswordGenerator and add login/pass manually to a DB via SQL. This way you have even more flexibility, you can have as many initial users as you want (and you can always delete them), and also this approach can guarantee that logins will be unique (you need some special handling in your code to check, that the login of any new user doesn't match the login of the first user).

Keycloak with vaadin and spring security

I want to secure my vaadin application with keycloak and spring security. I try to use the "keycloak-spring-security-adapter".
My problem is that I want also unauthenticated users to use my application, but with less functionality - I do this with method security and checking which roles the current user has in the UI.
Can I configure the filter so that it ignores unauthenticated requests, but If the token is present uses it?
Thanks
Daniel
A working example of what you want can be found in the public-access branch of this github project. It does use Vaadin 8 though.
In essence, you can setup your application to be partially public, i.e. accessibly to unauthenticated user for certain parts and requires login for others, as follows:
#Configuration
#EnableWebSecurity
#EnableVaadinSharedSecurity
#EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true, proxyTargetClass = true)
public class SecurityConfiguration extends KeycloakWebSecurityConfigurerAdapter {
...
#Override
protected void configure(HttpSecurity http) throws Exception {
http.httpBasic().disable();
http.formLogin().disable();
http.csrf().disable();
http
.authorizeRequests()
.antMatchers("/vaadinServlet/UIDL/**").permitAll()
.antMatchers("/vaadinServlet/HEARTBEAT/**").permitAll()
.anyRequest().permitAll();
http
.logout()
.addLogoutHandler(keycloakLogoutHandler())
.logoutUrl("/sso/logout").permitAll()
.logoutSuccessUrl("/");
http
.addFilterBefore(keycloakPreAuthActionsFilter(), LogoutFilter.class)
.addFilterBefore(keycloakAuthenticationProcessingFilter(), BasicAuthenticationFilter.class);
http
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint());
http
.sessionManagement()
.sessionAuthenticationStrategy(sessionAuthenticationStrategy());
}
...
}
The line http.anyRequest().permitAll(); is the most important where you configure the filter to just allow all requests. You could still update this to only allow public access to certain urls.
You can then use spring security annotations on methods/views/components to configure your fine-grained access control. E.g:
#SpringComponent
#Secured("ROLE_ANONYMOUS")
public class LoginOperation implements Runnable {
#Override
public void run() {
// login logic
}
}
and
#Secured("ROLE_USER")
public class LogoutOperation implements Runnable {
#Override
public void run() {
// logout logic
}
}

log access denied events with Spring Security and J2EE container authentication

I've got spring security configured as
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = false)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.jee()
.mappableRoles("ROLE1", "ROLE2");
}
}
And then #Secured annotations with roles on the rest endpoints.
Doesn't matter what I do I don't seem to be able to create a custom handler for authorization (i.e. a user logged in successfully but doesn't have the right role to access a particular endpoint) error events.
What I tried was:
An exception handler with #ExceptionHandler(value = AccessDeniedException.class) - doesn't get called. I understand that's by design, ok.
AuthenticationEntryPoint configured as
http.exceptionHandling().authenticationEntryPoint(new RestAuthenticationEntryPoint())
#Component( "restAuthenticationEntryPoint" )
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {
#Override
public void commence( HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException ) throws IOException {
// logging
}
}
-doesn't get called
ApplicationListener - I can see it's getting called on context closed, so it's registered correctly but not called on authorization error.
All I need is a simple handler to log unsuccessful authorization events.
It completely slipped my mind that the allowed roles are listed in web.xml as well for j2ee container authentication to work. So any user without a least one of those roles was just being rejected by the container.
Otherwise the first, simplest, method works fine. Hopefully my mistake will help someone in the future
