CVE-2024-42499

5.3 MEDIUM

📋 TL;DR

This path traversal vulnerability in FitNesse allows attackers to check for file existence and potentially read partial file contents by manipulating pathnames. It affects all FitNesse installations prior to version 20241026. The vulnerability enables limited information disclosure about server file systems.

💻 Affected Systems

Products:
  • FitNesse
Versions: All versions prior to 20241026
Operating Systems: All platforms running FitNesse
Default Config Vulnerable: ⚠️ Yes
Notes: All default FitNesse configurations are vulnerable if running affected versions.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could map server file structure, identify sensitive files, and potentially read partial contents of configuration files or other sensitive data, leading to further attacks.

🟠

Likely Case

Attackers can enumerate file paths to understand server structure and potentially read limited portions of files, though full file reading appears restricted by the vulnerability description.

🟢

If Mitigated

With proper network segmentation and access controls, impact is limited to information disclosure about file existence within accessible directories.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: LOW

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Path traversal vulnerabilities typically have low exploitation complexity, though this specific vulnerability appears to have limitations on what can be read.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 20241026

Vendor Advisory: https://github.com/unclebob/fitnesse/releases/tag/20241026

Restart Required: Yes

Instructions:

1. Download FitNesse version 20241026 from https://fitnesse.org/FitNesseDownload
2. Stop the FitNesse service
3. Replace the FitNesse installation with the new version
4. Restart the FitNesse service

🔧 Temporary Workarounds

Network Access Restriction

all

Restrict network access to FitNesse to trusted IP addresses only

Web Application Firewall

all

Implement WAF rules to block path traversal patterns

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate FitNesse from sensitive systems
  • Monitor logs for path traversal patterns and unauthorized access attempts

🔍 How to Verify

Check if Vulnerable:

Check FitNesse version - if it's older than 20241026, it's vulnerable

Check Version:

Check the FitNesse web interface footer or startup logs for version information

Verify Fix Applied:

Verify FitNesse version is 20241026 or newer

📡 Detection & Monitoring

Log Indicators:

  • Unusual file path requests containing '../' sequences
  • Requests for non-standard file paths or extensions
  • Multiple failed file access attempts

Network Indicators:

  • HTTP requests with path traversal patterns (../, ..\, encoded equivalents)
  • Unusual file extension requests to FitNesse endpoints

SIEM Query:

source="fitnesse.log" AND (http_request="*../*" OR http_request="*..\\*")
