_csrf 令牌在 2 种形式中相同 JSP（CSRF 保护）

Question

我想保护我的应用程序免受跨站请求伪造 (CSRF) 攻击，所以我将其添加到我的

applicationContext.xml:

<security:global-method-security secured-annotations="enabled" />

        <security:http auto-config="true">
            <security:csrf/>    
            <security:intercept-url pattern="/**" access="permitAll"    />
        </security:http>

<security:authentication-manager/>

这是我的 web.xml

<!-- spring security csrf -->
        <filter>
            <filter-name>springSecurityFilterChain</filter-name>
            <filter-class>fr.telecom.support.context.DevicesSecurityFilter</filter-class>
        </filter>    
        <filter-mapping>
            <filter-name>springSecurityFilterChain</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>

这是我的过滤器

public class DevicesSecurityFilter extends DelegatingFilterProxy {

    public DevicesSecurityFilter() {
        // TODO Auto-generated constructor stub
    }

    public DevicesSecurityFilter(Filter delegate) {
        super(delegate);
    }

    public DevicesSecurityFilter(String targetBeanName) {
        super(targetBeanName);
    }

    public DevicesSecurityFilter(String targetBeanName,
            WebApplicationContext wac) {
        super(targetBeanName, wac);
    }

    public void doFilter(ServletRequest request,
                         ServletResponse response,
                         FilterChain filterChain) throws ServletException, IOException {


        HttpServletRequest httpServletRequest;
        ThreadContext threadContext;

        if (request instanceof HttpServletRequest) {
            httpServletRequest = (HttpServletRequest) request;
            threadContext = ThreadContext.getInstance();

            try {
                EcasUser ecasUser = (EcasUser) httpServletRequest.getUserPrincipal();
                if (ecasUser != null) {
                    threadContext.setDomainUsername(ecasUser.getDomainUsername());
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
            threadContext.setUserID(httpServletRequest.getRemoteUser());
        }

        System.out.println ("filterChain -> " + filterChain );  

        if (filterChain != null) {

            filterChain.doFilter(request, response);

        }
    }

有1个JSP有2种形式，如下：当我提交第一个表单时一切正常，但是当我提交第二个表单时，出现以下错误：

此错误（HTTP 403 禁止访问）表示 Internet Explorer 可以连接到该网站，但没有查看该网页的权限。有关 HTTP 错误的详细信息，请参阅帮助。

<form name="buttonpanelform1" action="products.do" method="POST">

  <input type="hidden" name="_csrf" value="470bb7e4-1985-42c8-92fe-0b5edbfcd432"/>

    <table align="center" border="0" cellpadding="10" cellspacing="0" width="100%">
       <tbody>
<tr>
    <td align="left">
    <input type="submit" name="btn_addItem" value="btn_addItem">

    <td align="right">

</tr>
</tbody>
</table>
</form>


<form name="addItemForm" class="special" action="products.do" method="POST" enctype="multipart/form-data" style="clear:both;">

                        <input type="hidden" name="_csrf" value="470bb7e4-1985-42c8-92fe-0b5edbfcd432"/>


<table align="center" border="0" cellpadding="10" cellspacing="0" width="100%">

   <input type="submit" name="btn_saveItem" value="btn_saveItem">

</form>

Answer 1

您的第二种形式使用多部分编码，因此 spring 安全过滤器无法提取 posted csrf 令牌。如果您的表单需要这种编码（它正在上传文件），您有 2 种可能的解决方案，由 spring 安全文档提供。

确保在请求到达 spring 安全过滤器链之前解析多部分数据，或者 post csrf 令牌作为表单操作属性中的请求参数。
