渗透测试工具-sqlmap使用

sqlmap是一个开源渗透测试的自动化工具，可以自动检测和利用SQL注入漏洞并接管数据库服务器。它配备了一个强大的检测引擎，许多用于终极渗透测试的利基功能，以及广泛的开关，包括数据库指纹识别、从数据库中获取数据、访问底层文件系统，以及通过带外连接在操作系统上执行命令。

特点

Sqlmap的主要特点如下。

●支持多种数据库：MySQL、Oracle、PostgreSQL、Microsoft SQL Server、MariaDB、Microsoft Access、IBM DB2、SQLite、Sybase等。

●支持6种SQL注入技术：布尔盲注、时间盲注、显错式注入、联合查询注入、堆查询注入和OOB（Out-Of-Band，带外数据）注入。

●支持用户名、数据库、数据表、字段等信息的枚举。●支持自动识别密码哈希格式，并使用字典破解密码。●支持在所有数据库中搜索特定的数据库名、数据表名和字段。由于SQL注入漏洞的存在范围较广、危险性较大，Sqlmap强大的检测引擎为渗透测试提供了极大的便利。

安装

sqlmap是用python语言编写的，在安装Sqlmap之前，需要先安装Python 2.6/2.7或Python 3.x。

Sqlmap的参数Sqlmap的选项参数有Target、Request、Injection、Brute force等13类，较常用的有以下4类。

●Target：确定SQL注入检测和攻击的目标，如指定URL。

●Request：定义如何连接目标URL，也就是定义请求内容，如指定Cookie的值。

●Injection：指定要测试的参数、提供payload等，如指定注入点。

●Enumeration：最常用且最重要的选项参数，主要用来枚举信息，如数据库、数据表和字段等信息。 

常用参数及说明

常见的Sqlmap参数使用方法如下

(1)GET型注入使用参数“-u”指定SQL注入的URL，URL中包含GET请求参数。 

(2)POST型注入

使用参数“-u”指定SQL注入的URL，参数“--data”指定POST请求的数据体。 

(3)带Cookie参数的注入

使用参数“-u”指定SQL注入的URL，参数“--cookie”指定请求中携带的Cookie值。 

 

(4)枚举所有数据库名

 使用参数“-u”指定SQL注入的URL，参数“--dbs”枚举所有的数据库。

(5)枚举指定数据库所有数据表的表名

使用参数“-u”指定SQL注入的URL，参数“--tables”枚举所有的数据表，参数“-D”指定枚举数据表所在的数据库。 

示例

测试使用bwapp靶机

1、get+cookie

SQL Injection (GET/Search)，级别low，使用burpsuite代理，操作搜索抓到get方法。

然后复制url至sqlmap进行测试。

python sqlmap.py -u "http://locahost/sqli_1.php?title=a&action=search" --cookie="PHPSESSID=2jm70f1ms8rv5hs3m58p7ugan0; security_level=0"

先找到了title参数为动态的，可注入的injectable
参数title可能存在XSS攻击
接着测试了'AND boolean-based blind - WHERE or HAVING clause'
testing 'Boolean-based blind - Parameter replace (original value)'
testing 'Generic inline queries'
testing 'AND boolean-based blind - WHERE or HAVING clause (MySQL comment)'
结论：存在布尔注入，基于错误的注入，基于时间的盲注，UNION查询。
