This tweet highlights how skilled penetration testers bypass Web Application Firewalls (WAFs) to uncover vulnerabilities that might be hidden behind firewall defenses. It underlines the fact that attackers often find ways to circumvent security measures like WAFs, which means relying solely on them can leave security gaps. Penetration testers simulate these attacks to identify unseen risks, providing a comprehensive view of an organization's security posture. However, the tweet does not specify which type of vulnerability is exploited or provide a specific payload or WAF vendor. It serves as a reminder of the importance of thorough security testing beyond just relying on WAFs.
