2.3 Code Injection Attack

Question 1

What is a code injection attack?

Answer 1

A prevalent application attack where an attacker inserts their own malicious code into the data being input into an application.

Question 2

What makes a code injection attack unauthorized?

Answer 2

It involves inserting malicious code that disrupts the application’s intended functionality and security.

Question 3

What is the primary factor for the success of a code injection attack?

Answer 3

The application’s failure to properly validate or sanitize incoming data.

Question 4

Who is responsible for preventing code injection attacks?

Answer 4

Application developers.

Question 5

What specific responsibilities do application developers have regarding code injection?

Answer 5

Implementing ‘checks’ within their code to prevent the injection of unnecessary or unwanted application data.

Question 6

What is the goal of the ‘checks’ that developers implement?

Answer 6

To ensure that only legitimate and intended input is processed.

Question 7

Can a code injection attack occur during normal input into an application? True/False

Answer 7

True.

Question 8

What kind of data is typically targeted by attackers in code injection attacks?

Answer 8

Data being input into the application.

Question 9

What could happen if an application lacks proper checks against code injection?

Answer 9

It could allow malicious code to be executed, leading to data breaches or system compromise.

Question 10

How common are code injection attacks?

Answer 10

They are described as a ‘very common application attack.’

Question 11

Fill in the blank: A code injection attack exploits vulnerabilities in how applications handle and process _______.

Answer 11

user-supplied input.

Question 12

What is malicious code?

Answer 12

Software code designed to cause harm, gain unauthorized access, or perform unwanted actions on a computer system or network.

Question 13

Define ‘checks’ in the context of code injection prevention.

Answer 13

Security measures or validation routines implemented by developers to scrutinize incoming data.

Question 14

What does ‘unnecessary or unwanted application data’ refer to?

Answer 14

Data that is either irrelevant to the application’s intended function or carries malicious intent.

Question 15

Who are application developers?

Answer 15

Individuals or teams responsible for designing, building, testing, and maintaining software applications.

Question 16

What is an application attack?

Answer 16

A type of cyberattack that targets vulnerabilities within software applications.

Question 17

What broader implications do code injection attacks have?

Answer 17

They compromise data integrity and system security.

Question 18

What is one key security principle that application developers should uphold?

Answer 18

Validation of incoming data.

Question 19

How does a defense-in-depth strategy mitigate code injection risks?

Answer 19

By implementing multiple layers of security measures beyond basic input validation.

Question 20

What is the ideal state of application security concerning input handling?

Answer 20

To ensure that no code injection attacks are allowed.
