This tweet talks about bypassing the AWS WAF (Web Application Firewall) by using a technique to perform an SQL Injection (SQLi) attack. The bypass payload mentioned is a classic SQL injection payload: ' OR 1=1 –. This payload is used to manipulate SQL queries to return true conditions and potentially bypass security controls. AWS WAF is a popular cloud-based firewall service provided by Amazon Web Services that protects web applications from common web exploits. This bypass technique can confuse the WAF filter rules by injecting special SQL syntax that bypasses normal input validation, allowing attackers to access or manipulate the backend database. It is important to properly validate and sanitize all inputs at the application level and configure WAF rulesets carefully to prevent such bypass attempts.
