The document discusses SQL injection, a web security vulnerability that allows attackers to manipulate queries to a database. It distinguishes between in-band SQL injection, where results are retrieved via the same channel, and out-of-band SQL injection, where results are retrieved using a different channel. Additionally, it mentions inferential (blind) SQL injection, which makes detection more challenging due to a lack of feedback from the application.

1. SQL INJECTION
A type of SQL Injection where
the attacker receives the result
as a direct response using the
same communication channel.
This type of attack involves using a
different channel, such as email or
DNS, to retrieve the results of the
attack.
SQL injection (SQLi) is a web security
vulnerability that allows an attacker to
interfere with the queries that an application
makes to its database.
IN-BAND SQL INJECTION
OUT-OF-BAND SQL INJECTION
INFERENTIAL (BLIND) SQL INJECTION
In this type of attack, the attacker
does not receive any feedback from
the application about the success or
failure of the attack, making it more
difficult to detect.
