CVE-2023-2X8X1
This challenge covers the review of a CVE in a Java codebase and its patch
The Code Review Patch challenges aim to enhance your ability to identify and understand vulnerabilities in code by providing both the vulnerable code and its corresponding patch. In this particular lab, you will focus on a Java file from the grafana-connector project. The task is to locate a missing else statement in the LoginInterceptor.java file, which results in improper handling of unauthorized access attempts. Initially, you should try to spot the issue without referencing the patch, but if you struggle, the patch will guide you to the exact location of the problem.
The vulnerable code fails to handle cases where the authorization header is null, potentially allowing unauthorized access. The patch adds an else clause to ensure that if the authorization header is missing, the server responds with an unauthorized error. This change is crucial for maintaining the security of the authentication mechanism.
