Golang Code Review #03
This challenge covers the review of a snippet of code written in Golang.
In this lab, you are provided with a Go application consisting of several files, including main.go, handler/handler.go, and handler/routes.go. The main focus is on examining the code for vulnerabilities without relying on external guidance. The code utilizes various packages and libraries, such as libxml2, httprouter, and rice, to handle HTTP requests and XML processing.
A key area of concern is the ProcessXML function in handler.go, which processes XML data from user input. The function parses the XML content without sufficient validation, potentially exposing the application to XML External Entity (XXE) attacks. Identifying and mitigating such vulnerabilities is crucial for ensuring the security of the application.
