Gwendal Le Coguic's blog post offers a detailed tutorial on bypassing Cloudflare's Web Application Firewall (WAF) by identifying the origin server IP address. It highlights that Cloudflare, despite being a popular WAF provider used by over 16 million internet properties, can be susceptible to bypasses, emphasizing the need for continuous security testing. The post outlines methods to uncover the origin IP, such as leveraging DNS tools, examining mail headers, or exploiting XML-RPC pingbacks. It underscores the limitations of relying solely on WAFs, advocating for a combination of WAFs with other security measures like scanning tools to enhance web application protection. Detectify, a tool that uses crowdsourced hacker insights to test security, is recommended for users to reinforce their defenses. The article concludes by stressing the importance of identifying weak links in security configurations and invites readers to contribute additional strategies for bypassing Cloudflare protections.
