How do I disable resolving login parameters passed as url parameters / from the url

Question

The application logs all requested urls. This means, that it\'s critical not to authenticate using url parameters, because it would cause the situation in which

Answer 1

I would like to suggest an alternative which is based on spring-security rater then a workaround as suggested by chimmi.

This answer provide a solution to the issue suggested by xenteros on bres26 answer as well

Override the exiting UsernamePasswordAuthenticationFilter implementation

public class ImprovedUsernamePasswordAuthenticationFilter 
                                    extends UsernamePasswordAuthenticationFilter {

    @Override
    protected String obtainUsername(HttpServletRequest request) {
        final String usernameParameter = getUsernameParameter();
        validateQueryParameter(request, usernameParameter);
        return super.obtainUsername(request);
    }

    @Override
    protected String obtainPassword(HttpServletRequest request) {
        final String passwordParameter = getPasswordParameter();
        validateQueryParameter(request, passwordParameter);
        return super.obtainPassword(request);
    }

    private void validateQueryParameter(HttpServletRequest request, String parameter) {
        final String queryString = request.getQueryString();
        if (!StringUtils.isEmpty(queryString)) {
            if (queryString.contains(parameter))
                throw new AuthenticationServiceException("Query parameters for login are a prohibit, use message body only!");

        }
    }

 }

You need to replace your own implementation with the existing one (see doc here)

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/home","/login").permitAll()
                .anyRequest().authenticated()
                .and()
            .logout()
                .permitAll()
                .and()
             //Replace FORM_LOGIN_FILTER with your own custom implementation
             .addFilterAt(improvedUsernamePasswordAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
               .exceptionHandling()
               .authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/login"))
               .and()
            //disable csrf to allow easy testing
             .csrf().disable();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER");
    }

    public UsernamePasswordAuthenticationFilter improvedUsernamePasswordAuthenticationFilter() throws Exception {
        UsernamePasswordAuthenticationFilter authFilter = new ImprovedUsernamePasswordAuthenticationFilter();
        authFilter.setRequiresAuthenticationRequestMatcher(
                new AntPathRequestMatcher("/login", "POST")
         );
        authFilter
        .setAuthenticationManager(authenticationManager());
        authFilter
       .setAuthenticationSuccessHandler(
           new SavedRequestAwareAuthenticationSuccessHandler()
        );
       authFilter
       .setAuthenticationFailureHandler(
         new SimpleUrlAuthenticationFailureHandler("/login?error")
       );
        return authFilter;
    }
}

Advantages: it’s based on spring security and flexible to changes.
Disadvantage: Unfortunately I found Spring Java Config very hard to set and to read

EDIT: I accepted chimmi comment and overridden obtainUsername and obtainPassword
