During examination of Internet history records, the following string occurs within a Unique Resource Locator...

Structured Query Language (SQL) injection is a type of attack that exploits a vulnerability in a web application that does not properly validate or sanitize the user input before passing it to a database. An attacker can inject malicious SQL commands into the input field, such as a search box or a login form, and execute them on the database server. The injected SQL commands can be used to perform various actions, such as accessing, modifying, or deleting data, bypassing authentication, or executing commands on the server. The string in the question is an example of a SQL injection attack, where the attacker appends a logical expression “or 1=1” to the productid parameter, which will always evaluate to true and return all the records from the products table.
