Defending C++ Applications Against Path Traversal

When applications rely on untrusted input data to make security decisions without canonicalizing it, attackers could exploit these weaknesses to perform malicious actions. For instance, they could bypass checks for restricted resources, traverse file system directories, and redirect file system operations to unintended resources, which could cause significant damage to your organization.

This Defending C++ Applications Skill Lab provides a virtual environment that contains a vulnerable application and its complete source code. It trains developers to identify and mitigate canonicalization vulnerabilities before negatively impacting your organization.
