The Online Web Application Security Project (OWASP) helps organizations improve their security posture by offering guidelines based on real-world scenarios and community-led open-source projects. Out of the various threats, OWASP considers Code Injection to be a commonly known threat mechanism in which attackers exploit input validation flaws to introduce malicious code in an application.
This article explores how a code injection attack is performed, the types of attacks, and how software teams can protect their web applications from injection flaws.
What is Code Injection?
Threat actors take advantage of code injection vulnerabilities to embed malicious code into a source code, which the application interprets and executes. During the malicious injection, attackers leverage the fact that these systems construct part of a code segment using external data while lacking sufficient input validation. The malicious code is typically constructed to control the flow of data, leading to loss of confidentiality and reduced application availability.
Attackers identify user input validation flaws such as — data format,
