Intro to 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 other data that the application itself is able to access. In many cases, an attacker can modify or delete this data, causing persistent changes to the application's content or behavior.

• In some situations, an attacker can escalate an SQL injection attack to compromise the underlying server or other back-end infrastructure or perform a denial-of-service attack.

What's the impact of SQLi?

• Many high-profile data breaches in recent years have been the result of SQL injection attacks, leading to reputational damage and regulatory fines.

• In some cases, an attacker can obtain a persistent backdoor into an organization's systems, leading to a long-term compromise that can go unnoticed for an extended period.
