This leaves the API endpoint vulnerable to various web-based attacks such as SQL injection, cross-site scripting (XSS), and other common threats. Without AWS WAF in place, the API becomes more susceptible to attacks that could lead to data breaches, service disruptions, or the compromise of sensitive information. This weakens the API Gateway's overall security posture, increasing the risk of unauthorized access and malicious activities.
An attacker might attempt to exploit a vulnerability in the API Gateway by sending malicious input, such as an SQL injection payload, in a web request. Without a WAF, the malicious request could pass through to the backend system, potentially allowing the attacker to manipulate the database or gain unauthorized access to sensitive data. By attaching a WAF, malicious requests like these would be detected and blocked before they reach the API, preventing potential exploitation and ensuring that only legitimate traffic is processed.
