This course introduces ways to identify and mitigate this security weakness, referenced as CWE-22 by the CWE Top 25.

Topics include:

• Recognizing the impact of this vulnerability
• Techniques for finding path traversal issues through code review
• Application of secure coding best practices to prevent these attacks
• Testing to detect this security weakness
