Golang Code Review #02
This challenge covers the review of a snippet of code written in Golang.
In this lab, you are given snippets of Go code with potential security vulnerabilities. Your task is to review the code and pinpoint the issues without initially relying on the video guidance. The main.go file sets up the server to listen on a specified port and routes requests to handlers defined in handler.go and routes.go. Handler functions such as ServeImage read and serve files based on user input, which may introduce security flaws like path traversal vulnerabilities. Understanding and identifying these vulnerabilities is crucial for ensuring the security of web applications.
The handler.go file contains functions for rendering templates and serving images. The ServeImage function reads a file path from user input and serves the file's content without adequate validation, potentially allowing unauthorized file access. The routes.go file sets up URL routing and serves static files. The code uses the rice package to manage embedded resources. By thoroughly reviewing these snippets, you can enhance your skills in spotting and addressing security vulnerabilities in Go applications.
