This tweet discusses a scenario in web application security where even if parameterized queries and a WAF are used, attackers may still exploit weak points to extract data. One example is second order SQL injection, where input that appears safe initially is later used unsafely in the system. Additionally, attackers might bypass the WAF by employing obfuscation techniques to disguise their payloads. This highlights that while WAFs and parameterized queries are crucial defenses, attackers can find creative methods, like second order injections and obfuscated injections, to bypass protections and compromise data security. Developers should consider comprehensive security strategies beyond relying solely on WAF and parameterized queries, including thorough input validation, output encoding, and monitoring for unusual behavior.
