Golang Code Review #01
This challenge covers the review of a snippet of code written in Golang.
This lab focuses on identifying vulnerabilities within a given code snippet without external help initially. The main code consists of setting up an HTTP server that listens on a specified port and routes requests through handlers. In the handler/handler.go file, a potential vulnerability lies in the Redirect function, which redirects users to a URL specified by a query parameter without proper validation. This could lead to an Open Redirect vulnerability, allowing attackers to redirect users to malicious websites.
Moreover, the handler/routes.go file sets up the routes and serves static files from a directory. The inclusion of untrusted data in the redirect URL without proper validation or sanitization is a critical issue here. Understanding and identifying such vulnerabilities is crucial for securing applications and preventing potential security threats.
