Problem with some security filter. Project link: GitHub

Answer 1

The issue is related to SEC-2382 and can be resolved by updating to Spring Security 3.2.0.RELEASE. For reference, you will want to update the SecurityConfig as shown below:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private DataSource dataSource;

    @Autowired
    private UserDetailsService myCustomUserDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .jdbcAuthentication()
                .dataSource(dataSource)
                .and()
            .userDetailsService(myCustomUserDetailsService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/app/**").hasRole("ADMIN")
                .and()
            .formLogin()
                .loginPage("/index.jsp")
                .defaultSuccessUrl("/app/")
                .failureUrl("/index.jsp")
                .permitAll()
                .and()
            .logout()
                .logoutSuccessUrl("/index.jsp");
    }

}

Answer 2

Did you implement the filters in your web.xml?

 <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>-->
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

Answer 3

For those who face this issue post upgrade of 'springCloudVersion to 2020.0.3' or 'Spring boot to 2.5.0' or 'spring-security-web to 5.5.0', then the issue is because of bug. Technically with the filter order fetching scenario link and the issue causing commit is refer.

Workaround to fix this issue until we get a proper solution from Spring-security:

For instance, I have filters that should be executed in the following order

HeadersManipulator -> RequestLoggingFilter -> TokenValidatorFilter -> BasicAuthenticationFilter

Before spring security 5.5.0, filter ordering was maintained as:

@Component
@EnableWebSecurity
public class AppSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilterBefore(new TokenValidatorFilter(), BasicAuthenticationFilter.class);
        http.addFilterBefore(new RequestLoggingFilter(), TokenValidatorFilter.class);
        http.addFilterBefore(new HeadersManipulator(), RequestLoggingFilter.class);
    }
}

Post spring-security 5.5.0, adding a filter before/after to a custom defined filter has started not working and throwing below error

Caused by: org.springframework.beans.BeanInstantiationException: 
Failed to instantiate [javax.servlet.Filter]: 
Factory method 'springSecurityFilterChain' threw exception; 
nested exception is java.lang.NullPointerException

So the workaround is adding a preregistered filters as a second param as mentioned in the below snippet solves a problem.

@Component
@EnableWebSecurity
public class AppSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilterBefore(new HeadersManipulator(), BasicAuthenticationFilter.class);
        http.addFilterBefore(new RequestLoggingFilter(), BasicAuthenticationFilter.class);
        http.addFilterBefore(new TokenValidatorFilter(), BasicAuthenticationFilter.class);
    }
}

NOTE: the filter order is preserved as same as the filter registration.
