This tweet requests advanced methods to bypass Web Application Firewalls (WAF) for exploiting Cross-Site Scripting (XSS) vulnerabilities. The user is asking for simple placeholder examples that show how to bypass WAF protections. Although the specific WAF vendor is not mentioned, the request is centered around XSS vulnerability exploitation. Bypassing WAFs typically involves encoding payloads, breaking up scripts, or using obfuscated characters to evade detection. The user seeks a list of advanced techniques that can effectively bypass various WAF protections to test or exploit XSS targets. Providing such methods requires understanding how WAFs inspect input and what parsing they do. Common advanced methods include using alternate encodings (e.g., UTF-7, Unicode), injecting null bytes or comments to split payloads, leveraging event handlers in HTML, and using uncommon HTML tags or attributes. These approaches aim to execute scripts despite WAF rules designed to block typical XSS payloads. It is important for security researchers and bug bounty hunters to know these techniques to test security rigorously and responsibly disclose findings.
