Code injection is the exploitation of a computer bug that is caused by processing invalid data. Code injection can result in data loss, corruption, or denial of service.
Injection flaws are very common in web applications.
Code injection attacks are possible when an application allows user input without properly validating or sanitizing it. This can allow an attacker to supply malicious input that will be executed by the application. For example, if an attacker can submit input that will be treated as code by the application, they can execute arbitrary code and take control of the application.
There are many different types of code injection attacks, but they all exploit the same vulnerability. The most common type of code injection is SQL injection.
This is where an attacker can supply input that will be treated as SQL code by the application. The attacker can then execute arbitrary SQL queries and take control of the database.
Squarespace is a popular website builder and content management system. However, it is also vulnerable to code injection attacks. Attackers can inject malicious code into Squarespace websites to take control of the site or steal data.
If you are using Squarespace, be sure to keep your software up to date and exercise caution when inputting data into the system.
Other types of code injection include:
- Command Injection: where an attacker can supply input that will be treated as system commands by the application.
- PHP Code Injection: where an attacker can supply input that will be treated as PHP code by the application.
- JavaScript Injection: where an attacker can supply input that will be treated as JavaScript code by the application.
