This tweet describes a scenario where the user bypassed a Web Application Firewall (WAF) using a simple break in HTML code. While the exact WAF vendor and vulnerability type are not specified, the technique involved injecting a break element in the HTML to evade detection or filtering by the WAF. This method can be effective against various vulnerabilities since it manipulates the HTML structure that WAFs monitor and filter. The user mentions the process was annoying but ultimately easy, highlighting that simple, creative approaches can sometimes bypass complex security measures. This case emphasizes the importance of robust and context-aware filtering in WAFs to prevent such bypasses.
