Defending Go Applications Against Path Traversal

Path Traversal vulnerabilities in Go applications occur when user input is concatenated with a string to form a path to access filesystem objects without proper validation and authorization checks. This lab offers hands-on experience testing for Path Traversal vulnerabilities and implementing suitable mitigations. Potential mitigations include resolving path traversal characters, removing extraneous duplicate characters, resolving embedded environment variables, and anchoring to a fixed location. The virtual environment provides a vulnerable application and its complete source code for developers to identify and remediate Path Traversal vulnerabilities effectively, preventing unauthorized access to filesystem objects and ensuring application integrity and security.
