What Is Path Traversal?

Path traversal occurs when an attacker manipulates a filename or directory path to access information outside the location an application intended to expose. Certification exams may describe input containing directory-navigation characters and ask candidates to identify the vulnerability or the most effective control. A vulnerable download function might allow a user to request configuration files, credentials, application source code, or operating-system data instead of an approved document. Developers should avoid building file paths directly from user input, use fixed identifiers, normalize paths, restrict file permissions, and verify that the resolved location remains inside the approved directory. During investigation, analysts should review request logs, unusual filenames, error responses, and access to sensitive files to determine whether exploitation succeeded.
