Spring Boot + Security - Cannot load file (multi-page) when CSRF is enabled

Question

I want to download files from my angularJS client. I have enabled CSRF protection and works fine, except when I try to upload a file where I get an error 403:

An invalid CSRF token "null" was found in the request parameter "_csrf" or the header "X-XSRF-TOKEN".

But the token is in the request headers and is correct! When I turn off CSRF protection, I can upload files without problems.

In addition, CSRF protection works great.

Here is my current configuration:

SecurityConfiguration.java

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private SecurityUserDetailsService securityUserDetailsService;
    @Autowired
    private AuthFailureHandler authFailureHandler;
    @Autowired
    private AjaxAuthSuccessHandler ajaxAuthSuccessHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
                .exceptionHandling()
                .authenticationEntryPoint(authFailureHandler)
                .and()
                .authorizeRequests()
                .antMatchers(
                        "/",
                        "/index.html",
                        "/styles/**",
                        "/bower_components/**",
                        "/scripts/**"
                ).permitAll().anyRequest()
                .authenticated()
                .and().formLogin().loginPage("/login").permitAll()
                .and().logout().logoutUrl("/logout").logoutSuccessHandler(ajaxAuthSuccessHandler).permitAll()
                .and().httpBasic()
                .and().addFilterAfter(new CsrfHeaderFilter(), CsrfFilter.class)
                .csrf().csrfTokenRepository(csrfTokenRepository());
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .userDetailsService(securityUserDetailsService)
                .passwordEncoder(new BCryptPasswordEncoder());
    }

}

CsrfHeaderFilter.java

public class CsrfHeaderFilter extends OncePerRequestFilter {
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException {

        CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName());
        if (csrf != null) {
            Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
            String token = csrf.getToken();
            if (cookie == null || token != null && !token.equals(cookie.getValue())) {
                cookie = new Cookie("XSRF-TOKEN", token);
                cookie.setPath("/");
                response.addCookie(cookie);
            }
        }
        filterChain.doFilter(request, response);
    }
}

And the last thing I added is SecurityWebApplicationInitializer, as indicated here .

SecurityWebApplicationInitializer.java

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
    @Override
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
        insertFilters(servletContext, new MultipartFilter());
    }

}

?

: , 403.

@Configuration
public class MultipartUploadConfig {

    @Bean(name = "filterMultipartResolver")
    public MultipartResolver multipartResolver() {
        return new CommonsMultipartResolver();
    }
}

Answer 1

, CSRF url. html-.

<form .... th:action="@{/upload(${_csrf.parameterName}=${_csrf.token})}">
...
</form>

Answer 2

Ajax, url, :

url: "/uploadFile?${_csrf.parameterName}=${_csrf.token}"

:

function uploadFile() {
      $.ajax({
        url: "/uploadFile?${_csrf.parameterName}=${_csrf.token}",
        type: "POST",
        data: new FormData($("#upload-file-form")[0]),
        enctype: 'multipart/form-data',
        processData: false,
        contentType: false,
        cache: false,
        success: function () {
          // Handle upload success
          $("#upload-file-message").text("File succesfully uploaded");
        },
        error: function () {
          // Handle upload error
          $("#upload-file-message").text(
              "File not uploaded (perhaps it too much big)");
        }
      });
    }
