在网络安全领域,SQL注入(SQL Injection)是一种常见的攻击手段。特别是MySQL数据库中,攻击者可以利用延时注入(Time-Based SQL Injection)来绕过应用程序的安全防护,从而获取敏感信息。本文将围绕MySQL延时注入进行深入讨论,并提供相关代码示例,以便读者更好地理解这一攻击方式。 什么是延时注入? 延时注入是SQL注入的一种...

本节实例将以WebGoat Injection/SQL Injection第7篇的实例进行讲解,该实例在输入框中输入账户名称,点击Get Account Info按钮,就能够获取相关账户的信息,如输入Smith,就能够获取Smith的相关信息,如图2-1所示。 图2-1 Smith的相关信息 通过文中的介绍可知,该查询执行的SQL语句为select * from users where name = '...
SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. It generally allows an attacker to view data that they are not normally able to retrieve. This might include data belonging to other users, or any oth...

2.Error-based SQL injection(报错型注入) 报错注入的核心思想是通过数据库的“人性化的报错定位机制”将我们要查询的数据通过报错的方式直接回显到页面上来,示例语句:’ and (extractvalue(1,concat(0x7e,(select user()),0x7e)))–+,当然如果报错的数据不能回显到页面上来,就无法使用报错注入,这时候我们就可...
