SSRFuzz - A Tool To Find Server Side Request Forgery Vulnerabilities, With CRLF Chaining Capabilities


SSRFuzz is a tool to find Server Side Request Forgery vulnerabilities, with CRLF chaining capabilities


Why?
  • I wanted to write a tool in Golang for concurrency
  • I wanted to fuzz parameters for SSRF vulnerablities, as well as fuzz both paths and parameters for CRLF injections
  • I was inspired by Orange's work for chaining these types of vulnerabilities together (https://blog.orange.tw)

Installation

Run the following command to intsall

go get -u github.com/ryandamour/ssrfuzz
