A Code injection is an attack where an attacker inserts malicious code into an application’s code base or a website’s backend. The injected code can manipulate the behavior of the application, steal data, or grant unauthorized access. Common forms of code injection include SQL injection (where malicious SQL commands are inserted into input fields) and script injections, which can lead to cross-site scripting (XSS) attacks.
Example:
In an e-commerce website, an attacker inserts a malicious SQL query into a user’s search input field. This query manipulates the website’s database, allowing the attacker to access sensitive information such as customer names, addresses, and payment details, which can then be used for fraud.
