Broken Authentication
Building production-grade authentication servers is a critical challenge that full-stack and backend developers must overcome: - Authentication servers are part of almost all real-world production workflows. - Authentication servers can be a common source of vulnerabilities that may lead to a total platform compromise if implemented incorrectly. - Authentication servers handle PII (personally identifiable information) that users entrust to you, so great care is required to keep that information safe. In many places, protecting this data is also a legal requirement. In this lab, you've inherited a broken authentication server in your new role as a Senior Backend Developer at Globomantics. By following the steps, you'll identify vulnerabilities and repair them while maintaining the overall structure and behavior of the original server.

Challenge
Investigate Authentication Server Issues
In this objective, you'll investigate a broken authentication server by running the application and interacting with it through a debugging utility. You'll identify flaws in the authentication logic that allow users to log in without a valid password and access confidential user information that should not be exposed.

Challenge
Analyze Vulnerability Root Causes and Remediate Authentication Server Issues
Now that you've identified two key flaws in the authentication process that compromise the server, it's time to dive into the code and fix the problems.
