404 error after Cockpit upgrade to 7.9+

After upgrading Camunda (incl. cockpit) from version 7.8 to 7.9 I get a 404 error on ‘cockpit/plugin/cockpitPlugins/static/app/plugin.css’ with the following message in the backend:

2019-04-19 09:06:09.524 WARN 16004 — [ XNIO-1 task-46] ExceptionHandler : org.camunda.bpm.engine.rest.exception.RestException: It was not able to load the following file ‘app/plugin.js’.

My current setup is a Spring Boot 2.1.3.RELEASE application with:
mavenBom “org.camunda.bpm:camunda-bom:${camunda_version}”
compile(‘org.camunda.bpm.springboot:camunda-bpm-spring-boot-starter:3.2.1’)
compile(‘org.camunda.bpm.springboot:camunda-bpm-spring-boot-starter-rest:3.2.1’)
compile(‘org.camunda.bpm.springboot:camunda-bpm-spring-boot-starter-webapp:3.2.1’)

What can I do?

I am struggling with the very same issue.

My setup:

// Spring Boot (2.1.6.RELEASE) Gradle (5.5.1) plugin for dependency management:
dependencySet(group: 'org.camunda.bpm.springboot', version: '3.3.3') {
                    entry 'camunda-bpm-spring-boot-starter-webapp'
                    entry 'camunda-bpm-spring-boot-starter-rest'
                    entry 'camunda-bpm-spring-boot-starter-test'
                }
// my subproject (multi-project setup) uses "implementation" for all three dependencies

It loads http://localhost:8090/app/welcome/default/#!/welcome without any issue, but once I click on “Cockpit” (or Tasklist, Admin) it fails with the same exception as above AFAIK:

Will try to create a small project that fails the same way… but this will take quite some time. Maybe someone has an idea where I can look to try to identify the issue.

it seems like csrf filter causing issues. For workaround you can try below:

import org.springframework.boot.web.servlet.ServletContextInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class CsrfAutoConfiguration {
    private static final String CSRF_PREVENTION_FILTER = "CsrfPreventionFilter";
    
    @Bean
    public ServletContextInitializer csrfOverwrite() {
        return servletContext -> servletContext.addFilter(CSRF_PREVENTION_FILTER, (request, response, chain) -> chain.doFilter(request, response));
    }
}

Thank you @aravindhrs. I did a quick test by adding the bean and made sure it is called. However, the issue remains. I will check if I can find something that has a side effect in relation to the CSRF protection.

For instance, I can imagine that we configured Spring Security incorrectly :slight_smile: (it’s a complex beast). Right now we have:

public class SomeSecurityConfig {
    @Configuration
    @Order(1)
    @Profile({"!testing", "!no_security"})
    public static class CamundaSecurityConfiguration extends WebSecurityConfigurerAdapter {

        @Override
        public void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            http
                .authorizeRequests()
                .antMatchers("/app/**", "/lib/**", "/api/**", "/rest/engine/**")
                .permitAll()
                .and()
                    .csrf().disable(); // Camunda should have its own process for this: https://docs.camunda.org/manual/latest/webapps/shared-options/csrf-prevention/
            ;
            // @formatter:on
        }
    }

    @Configuration
    @Order(2)
    @Profile({"!testing", "!no_security"})
    public static class ApiSecurityConfiguration extends WebSecurityConfigurerAdapter {

        @Override
        public void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            http
                .authorizeRequests().anyRequest().authenticated()
                .and()
                .oauth2ResourceServer().jwt()
            ;
            // @formatter:on
        }
    }
} 

I could imagine that the .csrf().disable() conflicts in some way with the csrfOverwrite() Bean. Let’s see if I find something.

Edit
Ok, after experimenting a lot with different Web Security configurations I started to set breakpoints inside SpringBootCsrfPreventionFilter and as far as I can tell the issue is not connected to CSRF validation. Visiting /app/welcome/default/ works as expected; The application generates a CSRF token, validates it etc. pp. and shows me the page requested. But once I click on “Cockpit” my SpringBootCsrfPreventionFilter breakpoints are not reached and I get the above pasted exception. I feel like there is a mapping missing or something like that, i.e. the requested file http://localhost:8090/api/cockpit/plugin/cockpitPlugins/static/app/plugin.js?bust=7.11.0 is just not mapped to right JAR (camunda-webapp-webjar-7.11.0.jar).

I also confirmed that if I visit /app/welcome/default/ my breakpoint in org.camunda.bpm.admin.impl.web.AdminApplication#getClasses is reached. And if I visit http://localhost:8090/app/cockpit/default/ the one in org.camunda.bpm.cockpit.impl.web.CockpitApplication#getClasses is reached.

you can refer this post, if you’re facing issues with csrf filter.

Setting server.servlet.context-path in application.properties file, will solve this issue.

(or)

If you use camunda spring boot starter 3.3.0, it has a bug that would wrongfully apply the CSRF filter to the standalone REST API endpoints. So if you use 3.3.0 then upgrade to released 3.3.1 which should fix this.

@Gregor there’s a implementation for csrf validation in the dependency camunda-webapp-7.11.0-classes.jar
You can enable breakpoints and debug this class org.camunda.bpm.webapp.impl.security.filter.CsrfPreventionFilter.class

I’m using Camunda Spring Boot Starter 3.3.3 and also did see the post you reference (Issues after enabling CSRF Prevention Filter). I did try to change server.servlet.context-path to /camunda, issue remains. As the exception is thrown in org.camunda.bpm.webapp.plugin.resource.AbstractAppPluginRootResource#getAsset I assume the whole Spring Security / CSRF filtering succeeded. There would be no reason to access the resource (app/plugin.js) from disk if any of the security related filters did not succeed/approve the request?! I also “disabled” Spring Security by removing any configuration and only keep this one:

 public void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            http
                .authorizeRequests()
                .antMatchers("/**")
                .permitAll()
                .and()
                    .csrf().disable()
            ;
            // @formatter:on
        }

for camunda 7.11, I hope its not required to disable .csrf().disable()

First of, let me thank you @aravindhrs for helping me out and trying to resolve the issue! I am very thankful.

If I do not disable Spring Security’s CSRF protection stops me from logging in (on submitting Camunda’s login form):

2019-08-11 14:01:06.680 DEBUG 25756 --- [nio-8090-exec-9] o.s.security.web.FilterChainProxy        : /api/admin/auth/user/default/login/welcome at position 4 of 11 in additional filter chain; firing Filter: 'CsrfFilter'
2019-08-11 14:01:06.680 DEBUG 25756 --- [nio-8090-exec-9] o.s.security.web.csrf.CsrfFilter         : Invalid CSRF token found for http://localhost:8090/camunda/api/admin/auth/user/default/login/welcome

Note that I’ve set server.servlet.context-path=/camunda and the requested page is http://localhost:8090/camunda/app/welcome/default/#!/login.

What is interesting: Your suggested Bean method (404 error after Cockpit upgrade to 7.9+) is called, but the returned Lambda is never invoked , i. e. the Bean is registered(?), but chain.doFilter(request, response) is never called. Independent of me disabling or keeping CSRF protection enabled.

Yes, I have also added breakpoints to that one.

Anyway, right now I still try to understand what is going on. The proposed CSRF solutions do not work for me and I still have the feeling that it is not connected to CSRF at all as the call reaches org.camunda.bpm.webapp.plugin.resource.AbstractAppPluginRootResource#getAsset and with it also org.apache.catalina.core.ApplicationContext#getResourceAsStream where resources.getResource(validatedPath).getInputStream() is null for plugin.js and, if I execute it in the debugger, resources.getResource(validatedPath).exists() returns false (validatedPath is /plugin/cockpit/app/plugin.css which looks good to me).

It is something very obvious and stupid, I can feel it, just not see it… :slight_smile:

We did some more debugging, which included disabling Spring Security completely. As far as we can tell right now there is a Bug in Camunda Spring Boot Starter. Which is why I opened a bug report: https://app.camunda.com/jira/browse/CAM-10738.

Hi!

I facing the same problem. When click cockpit or admin, get 404 error code:

"message" : "It was not able to load the following file 'app/plugin.js'."
"status" : 404

And also:

status=404, 
error=Not Found,
message=Not Found, 
path=/api/admin/auth/user/default

My current version of spring and camunda:

Spring-Boot:  (v2.0.2.RELEASE)
Camunda BPM: (v7.11.0)
Camunda BPM Spring Boot Starter: (v3.3.4)

Same pattern with 2.1.5.RELEASE Spring Boot vesrsion.

As i understand, new Camunda versions (7.11+) have problems with xss protection.

With Camunda BPM 7.11.0 we have added the XSS Protection Header to all server responses in conjunction with the Webapps.

So, this CsrfAutoConfiguration java config helps me with my pet-project, but i need somehow to fix this problem on production project. Is this trouble still relevant?
