I have spring boot application with x509 authentication. My problem is that when authentication fails i get redirect loop instead of error screen.
When authentication fails i throw UsernameNotFoundException loadUserDetails from method in ArhivX509UserDetailsService.java
My code is as follows:

If you need more details please ask.
Applying permitAll() to /error401 means that when the security filterchain is finished executing, the request will be processed normally, regardless of whether or not there is an Authentication in the current SecurityContext.
X509ErrorCheckerFilter is forwarding all unauthenticated requests to /error401 from within the filterchain, so permitAll() is never applied. Instead, the forwarded request goes through the filterchain again and fails authentication, causing the circular redirect.
To resolve this, you have several options. Here are a couple:
1. Disable Security for error endpoints
you can disable security for endpoints using web.ignoring() in your SecurityConfiguration class. This is the simplest option.
#Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/error*");
}
2. Implement the ErrorController interface
The security filterchain will not be called for request mappings included in a controller that implements ErrorController.
See Spring's own BasicErrorController for reference(source).
This second option is preferable as it removes any requirement for a redirect in your filter. Instead, it lets Spring Security do the heavy lifting for routing requests through the auth process. As long as there's no authenticated Authentication in the session's SecurityContext when the security filterchain has finished processing, spring security will return a 401 and return the error page specified by your ErrorController.

auditorProvider seems to be called only once when application starts. authentication is called before it is set in doFilter. authentication object is always null and doesn't update when it's set later in doFilter. When I update a row in db, createdBy and lastModifiedBy are always null.
My doFilter seems to be called when an HTTP request is processed.
I followed a tutorial to learn spring security, but after troubleshooting for a few hours and followed through many similar tutorial, still can't figure out how to properly set the authentication in sequence so when I update a row, spring will update lastModifiedBy and createdBy automatically.
Your issue is that you are creating an anonymous AuditorAware but you are evaluating the SecurityContextHolder.getContext().getAuthentication() outside the body so whatever at that creation time will be kept inside the body.
#Bean
#Scope(value= ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public AuditorAware<String> auditorProvider() {
return () -> {
Authentication authentication
= SecurityContextHolder.getContext().getAuthentication();
return Optional.ofNullable(authentication)
.map(Authentication::getName);
};
}
You could say, you have SCOPE_PROTOTYPE but it is useless if it was autowired into a singleton instance that framework uses.
I am currently mapping pages using Page Controller.
Every page needs to check for Session, which is a duplicate code.
How do I avoid duplicating this code?
#Controller
public class PageController {
...
#RequestMapping("/view/List")
public String list(Map<String, Object> model) {
String session_chk = Utils.SessionCheck();
if(session_chk.equals("none")){
return "/view/manager/Login";
}
return "/view/member/List";
}
#RequestMapping("/view/Detail")
public String detail(Map<String, Object> model) {
String session_chk = Utils.SessionCheck();
if(session_chk.equals("none")){
return "/view/manager/Login";
}
return "/view/member/Detail";
}
...
You could use Spring Security to avoid all duplicate code related with securing your web application and also it provides buit-in protection against attacks such as session fixation, clickjacking or cross site request forgery. It is the de-facto standard for securing Spring-based applications.
Here you can find a nice series of tutorials to learn Spring Security.
Here you can find an small example in where you'll see how I handled a similar situation to yours using Spring Security configuration only.
This is my Spring Security configuration class
#Configuration
#EnableWebSecurity
public class SecSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user1").password(passwordEncoder().encode("user1Pass")).roles("USER")
.and()
.withUser("user2").password(passwordEncoder().encode("user2Pass")).roles("USER")
.and()
.withUser("admin").password(passwordEncoder().encode("adminPass")).roles("ADMIN");
}
#Override
protected void configure(final HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests()
// Only users with admin role will access views starting with /admin
.antMatchers("/admin/**").hasRole("ADMIN")
// Anonymous users (users without sessions) will access this URL
.antMatchers("/anonymous*").anonymous()
// Allowing all users to access login page
.antMatchers("/login*").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login.html")
.loginProcessingUrl("/perform_login")
.defaultSuccessUrl("/homepage.html", true)
.failureHandler(authenticationFailureHandler())
.and()
.logout()
.logoutUrl("/perform_logout")
.deleteCookies("JSESSIONID")
.logoutSuccessHandler(logoutSuccessHandler())
.and()
.exceptionHandling().accessDeniedPage("/accessDenied");
}
#Bean
public LogoutSuccessHandler logoutSuccessHandler() {
return new CustomLogoutSuccessHandler();
}
#Bean
public AuthenticationFailureHandler authenticationFailureHandler() {
return new CustomAuthenticationFailureHandler();
}
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
Add a filter which will redirect, and add check
#Component
public class SessionFilter extends OncePerRequestFilter {
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
if (!request.getRequestURI().contains("view/manager/Login") && "none".equals(Utils.SessionCheck())) {
httpResponse.sendRedirect("view/manager/Login.jsp");
//....
} else {
doFilterInternal(request, response, filterChain);
}
}
You can add it to all urls:
FilterRegistration sessionFilter = servletContext.addFilter("SessionFilter", SessionFilter.class);
sessionFilter.addMappingForUrlPatterns(null, false, "/*");
I have a Spring Boot application that is only exposing a REST API. I need to secure it and I'm using a token-based approach ― specifically JWT.
So far, this is what I have implemented:
//
// The Spring Security configuration class
#EnableGlobalAuthentication
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(final HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests()
.antMatchers("/api/login", "/api/logout").permitAll()
.antMatchers("/api/**").authenticated()
.anyRequest().authenticated()
.and()
.addFilterBefore(new JwtFilter(), BasicAuthenticationFilter.class)
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
}
//
// The JWT filter class to check for the token in the HTTP request (headers)
public final class JwtFilter extends GenericFilterBean {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
#Override
public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain) throws
IOException, ServletException {
final HttpServletRequest req = (HttpServletRequest)request;
final String header = req.getHeader("Authorization");
logger.debug("{} {}", req.getMethod(), req.getRequestURI());
if ((null == header) || !header.startsWith("Bearer ")) {
logger.debug("Missing or invalid Authorization header");
}
try {
// Check the token here; the implementation is not relevant here
/*SecurityContextHolder.getContext()
.setAuthentication(manager.authenticate(new JwtToken(JWTParser.parse(header.substring(7)))));*/
chain.doFilter(request, response);
} catch (final AuthenticationException e) {
SecurityContextHolder.clearContext();
// Do some other stuff here
} catch (final ParseException e) { /* ... */ }
}
}
The issue is that the filter executes correctly for every single URI, but I want to be able to exclude some endpoints from the same set. My API is placed in this context /api/* and I want to exclude, for instance, /api/login and /api/logout.
NOTE: My Spring Boot application.yml file doesn't have settings to enable/modify any security-related features.
Filters will be executed for all the endpoints that are configured through HttpSecurity. If you do not want filters to be applied for certain endpoints, include them in a method that configures WebSecurity. For example,
#Override
public void configure(WebSecurity web) throws Exception {
web
.ignoring()
.antMatchers("/api/login", "/api/logout");
}
Please read this post for more details.
I am doing the same as mentioned in the solution
#Override
protected void configure(HttpSecurity http) throws Exception {
http.cors()
.and().csrf().ignoringAntMatchers("/api/auth/**").disable()
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler)
.and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and().authorizeRequests()
.antMatchers("api/content/**").permitAll()
.anyRequest().authenticated();
http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);
}
#Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("api/auth/signup");
}
Every signup request is still hitting the doFilterInternal() method which was is a custom method.
While running EnableWebSecurity in debug mode i get :
Security filter chain:
[WebAsyncManagerIntegrationFilter
SecurityContextPersistenceFilter
HeaderWriterFilter
CorsFilter
LogoutFilter
AuthTokenFilter
RequestCacheAwareFilter
SecurityContextHolderAwareRequestFilter
AnonymousAuthenticationFilter
SessionManagementFilter
ExceptionTranslationFilter
FilterSecurityInterceptor ]
What should i do to solve this ?
I am using stateless spring security,but in case of signup i want to disable spring security.I disabled using
antMatchers("/api/v1/signup").permitAll().
but it is not working,i am getting error below:
message=An Authentication object was not found in the SecurityContext, type=org.springframework.security.authentication.AuthenticationCredentialsNotFoundException
I think this means spring security filters are working
My url's order always will be "/api/v1"
My spring config is
#Override
protected void configure(HttpSecurity http) throws Exception {
http.
csrf().disable().
sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).
and().
authorizeRequests().
antMatchers("/api/v1/signup").permitAll().
anyRequest().authenticated().
and().
anonymous().disable();
http.addFilterBefore(new AuthenticationFilter(authenticationManager()), BasicAuthenticationFilter.class);
}
My authentication filter is
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = asHttp(request);
HttpServletResponse httpResponse = asHttp(response);
String username = httpRequest.getHeader("X-Auth-Username");
String password = httpRequest.getHeader("X-Auth-Password");
String token = httpRequest.getHeader("X-Auth-Token");
String resourcePath = new UrlPathHelper().getPathWithinApplication(httpRequest);
try {
if (postToAuthenticate(httpRequest, resourcePath)) {
processUsernamePasswordAuthentication(httpResponse, username, password);
return;
}
if(token != null){
processTokenAuthentication(token);
}
chain.doFilter(request, response);
} catch (InternalAuthenticationServiceException internalAuthenticationServiceException) {
SecurityContextHolder.clearContext();
logger.error("Internal authentication service exception", internalAuthenticationServiceException);
httpResponse.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
} catch (AuthenticationException authenticationException) {
SecurityContextHolder.clearContext();
httpResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED, authenticationException.getMessage());
} finally {
}
}
private HttpServletRequest asHttp(ServletRequest request) {

private boolean postToAuthenticate(HttpServletRequest httpRequest, String resourcePath) {
return Constant.AUTHENTICATE_URL.equalsIgnoreCase(resourcePath) && httpRequest.getMethod().equals("POST");
}
private void processUsernamePasswordAuthentication(HttpServletResponse httpResponse,String username, String password) throws IOException {
Authentication resultOfAuthentication = tryToAuthenticateWithUsernameAndPassword(username, password);
SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);
httpResponse.setStatus(HttpServletResponse.SC_OK);
httpResponse.addHeader("Content-Type", "application/json");
httpResponse.addHeader("X-Auth-Token", resultOfAuthentication.getDetails().toString());
}
private Authentication tryToAuthenticateWithUsernameAndPassword(String username,String password) {
UsernamePasswordAuthenticationToken requestAuthentication = new UsernamePasswordAuthenticationToken(username, password);
return tryToAuthenticate(requestAuthentication);
}
private void processTokenAuthentication(String token) {
Authentication resultOfAuthentication = tryToAuthenticateWithToken(token);
SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);
}
private Authentication tryToAuthenticateWithToken(String token) {
PreAuthenticatedAuthenticationToken requestAuthentication = new PreAuthenticatedAuthenticationToken(token, null);
return tryToAuthenticate(requestAuthentication);
}
private Authentication tryToAuthenticate(Authentication requestAuthentication) {
Authentication responseAuthentication = authenticationManager.authenticate(requestAuthentication);
if (responseAuthentication == null || !responseAuthentication.isAuthenticated()) {
throw new InternalAuthenticationServiceException("Unable to authenticate Domain User for provided credentials");
}
logger.debug("User successfully authenticated");
return responseAuthentication;
}
My controller is
#RestController
public class UserController {
#Autowired
UserService userService;
/**
* to pass user info to service
*/
#RequestMapping(value = "api/v1/signup",method = RequestMethod.POST)
public String saveUser(#RequestBody User user) {
userService.saveUser(user);
return "User registerted successfully";
}
}
I am totally new to spring,please help me how to do it ?
When using permitAll it means every authenticated user, however you disabled anonymous access so that won't work.
What you want is to ignore certain URLs for this override the configure method that takes WebSecurity object and ignore the pattern.
#Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/api/v1/signup");
}
And remove that line from the HttpSecurity part. This will tell Spring Security to ignore this URL and don't apply any filters to them.
I have a better way:
http
.authorizeRequests()
.antMatchers("/api/v1/signup/**").permitAll()
.anyRequest().authenticated()
<http pattern="/resources/**" security="none"/>
Or with Java configuration:
web.ignoring().antMatchers("/resources/**");
Instead of the old:
<intercept-url pattern="/resources/**" filters="none"/>
for exp . disable security for a login page :
<intercept-url pattern="/login*" filters="none" />
This may be not the full answer to your question, however if you are looking for way to disable csrf protection you can do:
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/web/admin/**").hasAnyRole(ADMIN.toString(), GUEST.toString())
.anyRequest().permitAll()
.and()
.formLogin().loginPage("/web/login").permitAll()
.and()
.csrf().ignoringAntMatchers("/contact-email")
.and()
.logout().logoutUrl("/web/logout").logoutSuccessUrl("/web/").permitAll();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("admin").password("admin").roles(ADMIN.toString())
.and()
.withUser("guest").password("guest").roles(GUEST.toString());
}
}
I have included full configuration but the key line is:
.csrf().ignoringAntMatchers("/contact-email")
As #M.Deinum already wrote the answer.
I tried with api /api/v1/signup. it will bypass the filter/custom filter but an additional request invoked by the browser for /favicon.ico, so, I add this also in web.ignoring() and it works for me.
#Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/api/v1/signup", "/favicon.ico");
}
Maybe this is not required for the above question.
If you want to ignore multiple API endpoints you can use as follow:
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.csrf().disable().authorizeRequests()
.antMatchers("/api/v1/**").authenticated()
.antMatchers("api/v1/authenticate**").permitAll()
.antMatchers("**").permitAll()
.and().exceptionHandling().and().sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
I faced the same problem here's the solution:(Explained)
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers(HttpMethod.POST,"/form").hasRole("ADMIN") // Specific api method request based on role.
.antMatchers("/home","/basic").permitAll() // permited urls to guest users(without login).
.anyRequest().authenticated()
.and()
.formLogin() // not specified form page to use default login page of spring security.
.permitAll()
.and()
.logout().deleteCookies("JSESSIONID") // delete memory of browser after logout.
.and()
.rememberMe().key("uniqueAndSecret"); // remember me check box enabled.
http.csrf().disable(); **// ADD THIS CODE TO DISABLE CSRF IN PROJECT.**
}
This question is actually related to this issue problem.
Based on the suggestion from #harsh-poddar, I added the filter accordingly.
However, after adding that it seems like I can't login even with valid credential.
Following is the related code:
SecurityConfig
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
// #Bean
// public CustomAuthenticationEntryPoint customAuthenticationEntryPoint() {
// return new CustomAuthenticationEntryPoint();
// }
#Bean
public CustomExceptionTranslationFilter customExceptionTranslationFilter() {
return new CustomExceptionTranslationFilter(new CustomAuthenticationEntryPoint());
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
//Note : Able to login without this filter, but after adding this, valid credential also fails
.addFilterAfter(customExceptionTranslationFilter(), ExceptionTranslationFilter.class)
// .exceptionHandling()
// .authenticationEntryPoint(new customAuthenticationEntryPoint())
// .and()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.requestCache()
.requestCache(new NullRequestCache())
.and()
.httpBasic()
.and()
.csrf().disable();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(new CustomAuthenticationProvider());
}
}
CustomAuthenticationProvider
#Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
public CustomAuthenticationProvider() {
super();
}
#Override
public Authentication authenticate(final Authentication authentication) throws AuthenticationException {
final String name = authentication.getName();
final String password = authentication.getCredentials().toString();
if (name.equals("admin") && password.equals("password")) {
final List<GrantedAuthority> grantedAuths = new ArrayList<>();
grantedAuths.add(new SimpleGrantedAuthority("ROLE_USER"));
final UserDetails principal = new User(name, password, grantedAuths);
final Authentication auth = new UsernamePasswordAuthenticationToken(principal, password, grantedAuths);
return auth;
} else {
throw new BadCredentialsException("NOT_AUTHORIZED");
}
}
#Override
public boolean supports(final Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
CustomExceptionTranslationFilter
#Component
public class CustomExceptionTranslationFilter extends ExceptionTranslationFilter {
public CustomExceptionTranslationFilter(AuthenticationEntryPoint authenticationEntryPoint) {
super(authenticationEntryPoint);
}
}
CustomAuthenticationEntryPoint
public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
#Override
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized.");
}
}
p/s : sorry for the basic question, I'm really new in spring & spring security.
The intended design for AuthenticationEntryPoint is to start/initiate an authentication. However, your implementation CustomAuthenticationEntryPoint does not do this. Instead, it simply sends back an unauthorized response. Please see javadoc for AuthenticationEntryPoint for more details on implementation specifics.
Based on your configuration you are using HTTP Basic for authentication:
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic();
}
This specific configuration will automatically configure BasicAuthenticationEntryPoint which is an implementation of AuthenticationEntryPoint. The BasicAuthenticationEntryPoint will challenge the user with a http response header of WWW-Authenticate: Basic realm="User Realm" to authenticate, as per server protocol.
However, the fact that you are configuring your own CustomAuthenticationEntryPoint it will ultimately override the BasicAuthenticationEntryPoint which is not what you want to do.
The other post recommended this configuration which again is not what you want to do.
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic()
.and()
.exceptionHandling().authenticationEntryPoint(new CustomAuthenticationEntryPoint());
}
If your main goal is to provide a custom response to the user when authentication fails than I would propose a form login configuration with a configured AuthenticationFailureHandler. Here is the configuration:
http
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin().failureHandler(new DefaultAuthenticationFailureHandler())
.and()
.csrf().disable(); // NOTE: I would recommend enabling CSRF
Your implementation of DefaultAuthenticationFailureHandler would be:
public class DefaultAuthenticationFailureHandler implements AuthenticationFailureHandler {
#Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
// Set status only OR do whatever you want to the response
response.setStatus(HttpServletResponse.SC_FORBIDDEN);
}
}
The AuthenticationFailureHandler is specifically designed to handle a failed authentication attempt.
