0，Cloudera 管理页面相关debug端口

CDH 管理页面相关端口：
Cloudera Management Service 配置 --> 相关debug端口：8087，8084，8091，8086）

1，Hadoop端口未授权访问

解决方案：https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/HttpAuthentication.html
cloudera管理页面，配置hdfs

#配置修改：搜索auth
hadoop.security.authorization   ==> true (勾选）
hadoop.http.authentication.type ==> simple  

#配置修改：搜索core-site.xml，选择【core-site.xml 的群集范围高级配置代码段（安全阀）】，添加如下配置
hadoop.http.filter.initializers   ==> org.apache.hadoop.security.AuthenticationFilterInitializer
hadoop.http.authentication.simple.anonymous.allowed  ==> false
#设置--仅某用户可访问（可选）： /opt/cloudera/hadoop-http-auth-signature-secret   ==> /opt/cloudera/hadoop-http-auth-signature-secret
# [root@c73 ~]# cat /opt/cloudera/hadoop-http-auth-signature-secret
# hdfsadmin

访问hadoop web页面

hdfs-50070 (正确访问方式：http://ip:50070?user.name=hdfs)
yarn-8088 (正确访问方式：http://ip:8088/cluster?user.name=hdfs)

2，检测Jetty版本漏洞

CVE-2019-10247：Jetty version 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older
CVE-2022-2048： Jetty 9.4.46及之前版本、10.0.9 及之前版本、11.0.9及之前版本
CVE-2017-7657： Jetty versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x

临时修复办法：直接修改jetty版本号

vim jetty-xx.jar : %s @旧版本号@新版本号@g，例如：: %s @9.3.25.v20180904@9.4.49.v20220914@g
jetty版本号参考：https://www.eclipse.org/jetty/download.php
验证是否生效：http://ip:60010 （hbase web ui页面，f12查看header, 其中有Jetty version信息）
