CVE-2025-11182

6.5 MEDIUM

📋 TL;DR

This vulnerability in GTONE ChangeFlow allows attackers to traverse directory paths and download arbitrary files without integrity checks. It affects all versions up to v9.0.1.1, potentially compromising sensitive system files and enabling unauthorized code execution.

💻 Affected Systems

Products:
  • GTONE ChangeFlow
Versions: All versions to v9.0.1.1
Operating Systems: Any OS running ChangeFlow
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments of affected versions are vulnerable by default.

⚠️ 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

Complete system compromise through arbitrary file read/write, leading to sensitive data exposure, privilege escalation, and remote code execution.

🟠

Likely Case

Unauthorized access to sensitive configuration files, source code, or credentials stored on the server.

🟢

If Mitigated

Limited to reading non-critical files if proper file permissions and web server restrictions are in place.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Path traversal vulnerabilities typically have low exploitation complexity, especially when combined with download capabilities.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: http://www.gtone.co.kr/kr/application-lifecycle-management.php

Restart Required: Yes

Instructions:

1. Contact GTONE for patch availability. 2. If patch exists, download from vendor. 3. Backup configuration. 4. Apply patch. 5. Restart ChangeFlow service. 6. Verify fix.

🔧 Temporary Workarounds

Web Server Path Restriction

all

Configure web server to restrict access to parent directories

# Apache: Use 'AllowOverride None' in directory blocks
# Nginx: Use 'deny all' for sensitive paths

File Permission Hardening

linux

Restrict file system permissions for ChangeFlow directories

chmod 750 /path/to/changeflow
chown root:changeflow /path/to/changeflow

🧯 If You Can't Patch

  • Isolate ChangeFlow server in network segment with strict firewall rules
  • Implement web application firewall (WAF) with path traversal protection rules

🔍 How to Verify

Check if Vulnerable:

Check ChangeFlow version against affected range. Test with controlled path traversal payloads in non-production environment.

Check Version:

Check ChangeFlow web interface or configuration files for version information

Verify Fix Applied:

Test path traversal attempts after patch/configuration changes. Verify file download functionality validates paths.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file access patterns
  • Requests containing '../' sequences
  • Access to files outside expected directories

Network Indicators:

  • HTTP requests with path traversal payloads
  • Unexpected file downloads from ChangeFlow

SIEM Query:

source="changeflow" AND (uri="*../*" OR uri="*..\\*" OR status=200 AND filesize>threshold)
