What Is a Directory Traversal?
Directory traversal attacks attempt to access files outside the intended web directory by using '../' sequences.
The /etc/passwd file is a common target because it contains user account information on Linux systems.
If successful, attackers can access sensitive configuration files and escalate privileges.
How to Defend Against This Threat
Validate and sanitize all file path inputs.
Use a whitelist approach for file access.
Run applications with minimal permissions.
Disable direct access to sensitive system files.
Use security tools to detect and block such patterns.
