Performing Directory Traversal Testing

Performing Directory Traversal Testing

Overview

Cybersecurity skill for performing directory traversal testing. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing directory traversal testing"

• "Testing web applications for path traversal vulnerabilities that allow reading o"

• During authorized penetration tests when the application handles file paths in URL parameters or request bodies

• When testing file download, file view, or file include functionality

• For assessing Local File Inclusion (LFI) and Remote File Inclusion (RFI) vulnerabilities

• When evaluating template engines, logging systems, or report generators that reference files

• During security assessments of APIs that accept file names or paths as parameters

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Authorization: Written penetration testing agreement for the target
• Burp Suite Professional: For intercepting and modifying file path parameters
• ffuf: For fuzzing file path parameters with traversal payloads
• dotdotpwn: Automated directory traversal fuzzer (apt install dotdotpwn)
• SecLists: Traversal payload wordlists from Daniel Miessler's collection
• curl: For manual testing of traversal payloads

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}

1. Plan Operations — Define objectives, scope, and success criteria for directory traversal testing operations.
2. Prepare Environment — Set up tools, access, and data sources required for directory traversal testing.
3. Execute Core Workflow — Perform the directory traversal testing operations following established procedures.
4. Validate Results — Verify that results meet quality standards and objectives.
5. Report Findings — Document results, observations, and recommendations.
6. Follow Up — Track remediation actions and verify fixes where applicable.

Tools

• Analysis Platform — Data processing and visualization
• Collaboration Tools — Team coordination and knowledge sharing

Process

1. Design — Define interface, identify patterns, plan implementation
2. Implement — Write code following existing conventions, add tests
3. Verify — Run tests, check integration, validate behavior

Verification

• All directory traversal testing procedures executed completely and documented
• Findings validated against multiple data sources
• False positives identified and filtered
• Results documented with evidence and timestamps
• Recommendations provided with risk-based prioritization
