Burp Suite is an intercepting HTTP Proxy, and it is the defacto tool for performing web application security testing. The feature of Burp Suite that I like the most is `Generate CSRF PoC`. However, the function to automatically determine the content of the request is broken, and it tries to generate PoCs using `form` even for PoCs that cannot be represented by `form`, such as JSON parameters and PUT requests. In addition, multibyte characters that can be displayed in Burp Suite itself are often garbled in the generated CSRF PoC. These were the motivations for creating LazyCSRF.
