Introduction Vulnserver is a vulnerable server written by Stephen Bradshaw whose blog is located here: grey-corner. This server was written intentionally to be vulnerable, so we can learn fuzzing on it. It's kinda hard to learn fuzzing if we don't have any existing vulnerabilities in place to test ...

Introduction The vulnserver.exe server is a vulnerable server that was written specifically for fuzing purposes. Therefore the software intentionally contains vulnerabilities that we can exploit to gain control over the target operating system. Peach is a fuzzer that is capable of performing both generation and mutation based fuzzing. It ...

Introduction Vulnserver is a Windows TCP server running on port 9999. It was written by Stephen Bradshaw whose blog is located here. The server was intentionally written to be vulnerable, for the purpose of learning how to fuzz a real target. The problem is that when we're learning, we ...
