This tweet emphasizes that bypassing a Web Application Firewall (WAF) is often less about finding a technical flaw in the WAF itself and more about exploiting mistakes made by WAF administrators in configuring and managing the WAF. It suggests that many successful bypass attempts result from misconfigurations, poor security practices, or errors in setting up the firewall rules or policies. Therefore, improving WAF effectiveness depends heavily on proper configuration, regular updates, and diligent management by administrators rather than solely relying on the inherent capabilities of the WAF product.
