Course

In this lab, you are presented with both the original vulnerable code and the patch that addresses the vulnerability. Your task is to identify the issue in the original code by carefully analyzing it. It's important to attempt this without initially referring to the patch to build your code review and vulnerability detection skills. Once you have made your assessment, you can refer to the patch to verify your findings and understand how the vulnerability was mitigated.

The given code deals with accessing a repository via JNDI or RMI, which has been deprecated due to security concerns. The patch introduces deprecation annotations and throws `UnsupportedOperationException` for methods that attempt to use these outdated and insecure methods. This ensures that the old, vulnerable methods can no longer be used, enhancing the overall security of the application.
