This tweet discusses the default configuration of the Cloudflare Web Application Firewall (WAF). It notes that the default Cloudflare WAF setup mainly detects major, obvious attacks but can be bypassed with some effort. This implies that the default ruleset is not comprehensive enough to catch all attacks, including subtle or sophisticated exploits. The recommendation is to create a custom ruleset tailored to the specific application you want to protect. Custom rules may be created based on the particular vulnerabilities or attack vectors relevant to your app, providing better protection than the generic default rules. Since the tweet mentions no specific payload, it focuses on the general concept of bypassing default WAF rules by tailoring attacks that do not trigger those rules. This analysis highlights the importance of customizing WAF configurations for effective protection and the limitations of default security settings in cloud-based WAFs like Cloudflare.
