What exactly is SQL injection (SQLi)?
SQL injection is a web security flaw that allows an attacker to meddle with database queries made by an application. It generally enables an attacker to examine data that they would not otherwise be able to retrieve. This could include data belonging to other users or any other data that the programme has access to. In many circumstances, an attacker can alter or remove this data, resulting in long-term modifications to the application's content or behaviour.
An attacker can escalate a SQL injection attack to compromise the underlying server or other back-end infrastructure, or launch a denial-of-service attack in some cases.
What are the ramifications of a successful SQL injection attack?
Unauthorized access to sensitive data, such as passwords, credit card information, or personal user information, can arise from a successful SQL injection attack. SQL injection attacks have been the cause of many high-profile data breaches in recent years, resulting in reputational damage and regulatory fines. In some situations, an attacker can get a persistent backdoor into an organization's systems, resulting in a long-term compromise that can go undetected for a long time.
SQL injection vulnerabilities, attacks, and tactics come in a wide range of flavors and appear in a variety of contexts. Among the most prevalent SQL injection examples are:
-->Retrieving hidden data, in which you can change a SQL query to
retrieve more results.
-->Subverting application logic is the process of changing a query
in order to interfere with the application's logic.
-->UNION attacks, which allow you to retrieve data from many
database tables.
-->Examining the database, where you can extract information about
the database's version and structure.
-->Blind SQL injection is a type of SQL injection in which the
results of a query you control are not returned in the
application's answers.
