The flaw lies in the inefficient parsing of the Content-Disposition header, commonly used in multipart form submissions. An attacker can exploit this by sending specially crafted input that causes the parser to consume excessive CPU resources, leading to a denial-of-service (DoS) condition. Since virtually all Rails applications and many other Ruby web apps rely on Rack for multipart parsing, the attack surface is widespread and affects production systems at the framework level. The attack does not require authentication and can be triggered with a single malicious request, making it low-cost but high-impact. Furthermore, because the vulnerability is exploited during early request processing, it can bypass typical application-level protections.
