Angular Command Injection: Examples and Prevention

Angular is a popular web application framework used by over 1.5 million live websites, making it a target for attackers. Among the vulnerabilities that can affect Angular applications, command injection is notable, as it allows attackers to execute operating system commands on the server by exploiting user inputs. This can result in data theft, configuration changes, or server disruption. To mitigate this risk, developers should prioritize addressing common vulnerabilities, such as command injection, and implement preventive measures like filtering dangerous characters, using allowlists, and adhering to the principle of least privilege. While the command injection occurs on the back end, Angular can pass these vulnerabilities to it, necessitating a layered security approach that includes both front-end and back-end protections. The piece also emphasizes the importance of evaluating custom scenarios for enhanced security and suggests replacing OS commands with safer alternatives when possible.
