IBMAppScan检测不安全请求，禁用TRACE，OPTION等请求

背景
因项目安全检测出现不安全请求，处于安全考虑准备禁用TRACE,HEAD,PUT,DELETE,OPTIONS请求方式，项目中请求方只用GET,POST请求

tomact中实现

在tomcat的web.xml配置文件最后加上请求方式限制，配置如下，本次使用的tomcat 8.5.31

 的子元素  是可选的，如果没有  元素
这表示将禁止所有 HTTP 方法访问相应的资源。

  
      
        /*  
 		GET   
	    PUT   
	    HEAD   
	    TRACE   
	    POST   
	    DELETE   
	    OPTIONS 
      
      
      
           

springboot中实现

Spring boot使用内置tomcat，2.0版本以前使用如下形式

@Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                collection.addMethod("HEAD");
                collection.addMethod("PUT");
                collection.addMethod("DELETE");
                collection.addMethod("OPTIONS");
                collection.addMethod("TRACE");
                collection.addMethod("COPY");
                collection.addMethod("SEARCH");
                collection.addMethod("PROPFIND");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        //如果需要禁用TRACE请求，需添加以下代码：
        tomcat.addConnectorCustomizers(connector -> {
            connector.setAllowTrace(true);
        });
        return tomcat;
    }

2.0版本使用以下形式

@Bean
public ConfigurableServletWebServerFactory configurableServletWebServerFactory() {
    TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
    factory.addContextCustomizers(context -> {
        SecurityConstraint securityConstraint = new SecurityConstraint();
        securityConstraint.setUserConstraint("CONFIDENTIAL");
        SecurityCollection collection = new SecurityCollection();
        collection.addPattern("/*");
        collection.addMethod("HEAD");
        collection.addMethod("PUT");
        collection.addMethod("DELETE");
        collection.addMethod("OPTIONS");
        collection.addMethod("TRACE");
        collection.addMethod("COPY");
        collection.addMethod("SEARCH");
        collection.addMethod("PROPFIND");
        securityConstraint.addCollection(collection);
        context.addConstraint(securityConstraint);
    });
    return factory;
}

若上述方法均不生效，还可使用过滤器，限制不安全的请求,亲测有效

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class CorsFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) {
        // TODO Auto-generated method stub
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {
    
      	HttpServletRequest httpServletRequest = (HttpServletRequest) request;
    	HttpServletResponse httpServletResponse = (HttpServletResponse) response;
    	//获取请求方式
		String method=httpServletRequest .getMethod();
		
		//判断是否包含TRACE或TRACK请求
        if("TRACE".equals(method)||"TRACK".equals(method)){
             httpServletResponse.setHeader("Allow", "HEAD, DELETE, POST, GET, OPTIONS, PUT");
             httpServletResponse.setStatus(405);
             return;
         }
        chain.doFilter(request, response);

		//如果需要重定向到其他界面，可以用下面的方式
		
		//if("TRACE".equals(method)||"TRACK".equals(method)){
            //httpServletResponse.sendRedirect("/IPOS/User/login");
        //}else {
            //chain.doFilter(request, response);
        //}
    }

    @Override
    public void destroy() {
        // TODO Auto-generated method stub
    }
}

在启动类里注入

//bean注入
@Bean
    public FilterRegistrationBean corsFilterRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new CorsFilter());
        registration.addUrlPatterns("/*");
        registration.setName("corsFilter");
        //将其注册在其他过滤器的前面
        registration.setOrder(0);
        return registration;
    }
