Invalid CSRF Token 'null' was found on the

Question

After configuring Spring Security 3.2, _csrf.token is not bound to a request or a session object.

This is the spring security config:

<http pattern="/login.jsp" security="none"/>

<http>
    <intercept-url pattern="/**" access="ROLE_USER"/>
    <form-login login-page="/login.jsp"
                authentication-failure-url="/login.jsp?error=1"
                default-target-url="/index.jsp"/>
    <logout/>
    <csrf />
</http>

<authentication-manager>
    <authentication-provider>
        <user-service>
            <user name="test" password="test" authorities="ROLE_USER/>
        </user-service>
    </authentication-provider>
</authentication-manager>

The login.jsp file

<form name="f" action="${contextPath}/j_spring_security_check" method="post" >
    <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
    <button id="ingresarButton"
            name="submit"
            type="submit"
            class="right"
            style="margin-right: 10px;">Ingresar</button>
    <span>
        <label for="usuario">Usuario :</label>
        <input type="text" name="j_username" id="u" class="" value=''/>
    </span>
    <span>
        <label for="clave">Contrase&ntilde;a :</label>

        <input type="password"
               name="j_password"
               id="p"
               class=""
               onfocus="vc_psfocus = 1;"
               value="">
    </span>
</form>

And it renders the next html:

<input type="hidden" name="" value="" />

The result is 403 HTTP status:

Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.

UPDATE After some debug, the request object gets out fine form DelegatingFilterProxy, but in the line 469 of CoyoteAdapter it executes request.recycle(); that erases all the attributes...

I test in Tomcat 6.0.36, 7.0.50 with JDK 1.7.

I have not understood this behavior, rather than, it would be possible if someone point me in the direction of some application sample war with Spring Security 3.2 that works with CSRF.

Answer 1

Spring documentation to disable csrf: https://docs.spring.io/spring-security/site/docs/current/reference/html/csrf.html#csrf-configure

@EnableWebSecurity
public class WebSecurityConfig extends
WebSecurityConfigurerAdapter {

   @Override
   protected void configure(HttpSecurity http) throws Exception {
      http.csrf().disable();
   }
}

Answer 2

Neither one of the solutions worked form me. The only one that worked for me in Spring form is:

action="./upload?${_csrf.parameterName}=${_csrf.token}"

REPLACED WITH:

action="./upload?_csrf=${_csrf.token}"

(Spring 5 with enabled csrf in java configuration)

Answer 3

if you will apply security="none" then no csrf token will be generated. page will not pass through security filter. Use role ANONYMOUS.

I have not gone in details, but it is working for me.

 <http auto-config="true" use-expressions="true">
   <intercept-url pattern="/login.jsp" access="hasRole('ANONYMOUS')" />
   <!-- you configuration -->
   </http>

Answer 4

Try to change this: <csrf /> to this : <csrf disabled="true"/>. It should disable csfr.

Answer 5

Please see my working sample application on Github and compare with your set up.

Answer 6

With thymeleaf you may add:

<input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}"/>
