What Is Path Traversal?
Path traversal, also known as directory traversal, is a web security vulnerability that allows attackers to access unauthorized files and directories outside the intended scope of a web application. By manipulating file paths in user input, attackers can gain access to sensitive system files, application code, or even credentials stored on the server.
Why Is Path Traversal Dangerous?
A successful path traversal attack can lead to:
✅ Data Exposure – Attackers can read confidential files, such as /etc/passwd, configuration files, or application logs.
✅ System Compromise – Access to critical files may allow further exploitation, leading to full server control.
✅ Code Execution Risks – If combined with other vulnerabilities, attackers might execute malicious scripts.
✅ Loss of Customer Trust – Unauthorized access to sensitive data can result in compliance violations and reputational damage.
How Path Traversal Works
Web applications often process file paths in parameters for operations like downloading files, retrieving images, or handling logs. If user inputs are not properly validated, an attacker can manipulate the file path using sequences like:
This request attempts to navigate outside the intended directory and access system files.
Best Practices to Prevent Path Traversal Attacks
🔹 Use Allow Lists: Restrict file access to specific directories and filenames.
🔹 Sanitize User Input: Remove special characters like ../, %2e, and \ before processing file paths.
🔹 Use Absolute Paths: Avoid direct user-controlled file path handling; use predefined paths instead.
🔹 Implement Proper Access Controls: Enforce permission rules to prevent unauthorized file access.
🔹 Monitor File Access Requests: Detect unusual file requests in logs and block suspicious activity.
