This tweet points out a bypass technique involving WAF (Web Application Firewall) protection provided by Cloudflare through the use of Proxychain. The user implies that simply deploying Cloudflare's WAF is insufficient to ensure security if input sanitization is not robust. Proxychain is used as a method to bypass WAF protections, allowing testing or exploitation of vulnerabilities on the website. The tweet serves as a reminder that WAF alone, especially when implemented via cloud services like Cloudflare, should not be solely relied upon for security. Proper input sanitization and other security measures are essential to effectively protect web applications from attacks.
