The HTTP Garden – A Parser Vulnerability Research Tool▲75
I wrote this tool during an internship at Narf Industries in 2023. It's a REPL that allows for quickly developing, testing, and fuzzing for HTTP request smuggling attack payloads. I started the internship having never worked with web servers, and have now found over 100 HTTP implementation bugs. I attribute this mostly to the ease of experimentation in the Garden. REPL-oriented fuzzing is just a really good interface for finding parsing bugs. It's pretty neat to able to run a differential fuzzer, categorize and display all the discovered discrepancies, then let a human pick through them and…
