CVE-2025-2028
📋 TL;DR
This vulnerability allows man-in-the-middle attackers to intercept and modify CSV files containing IP-to-country mappings during download due to missing TLS certificate validation. It affects systems that download these mapping files for displaying country flags in logs. While the data is non-sensitive, manipulation could cause incorrect flag displays.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious content into the CSV file, potentially leading to code execution if the parsing logic has vulnerabilities, or cause denial of service by corrupting the mapping data.
Likely Case
Attackers could manipulate country flag displays in logs, causing confusion for administrators or misleading forensic investigations.
If Mitigated
With proper TLS validation, the risk is limited to potential service disruption if the download fails, but no security impact.
🎯 Exploit Status
Requires man-in-the-middle position between the system and the download server. No authentication bypass needed as the download occurs automatically.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Point Security Gateway and Management Hotfix for R81.20, R81.10, R81, R80.40, R80.30, R80.20
Vendor Advisory: https://support.checkpoint.com/results/sk/sk183349
Restart Required: No
Instructions:
1. Log into Check Point support center. 2. Download the appropriate hotfix for your version. 3. Install the hotfix via the management interface. 4. Verify the installation completes successfully.
🔧 Temporary Workarounds
Disable automatic CSV downloads
allPrevent the system from downloading IP-to-country mapping files automatically
Configure via Check Point management interface: Disable 'Download IP-to-country mapping' in log settings
Use internal download server with TLS validation
allHost the CSV file internally on a server with proper TLS certificates
Set up internal HTTP/HTTPS server with valid certificates and configure system to use this internal source
🧯 If You Can't Patch
- Monitor network traffic for unauthorized CSV file downloads or modifications
- Implement network segmentation to restrict CSV download traffic to trusted sources only
🔍 How to Verify
Check if Vulnerable:
Check if your Check Point version is in the affected range and if IP-to-country mapping downloads are enabled in log settings.Check Version:
In Check Point CLI: 'fw ver' or 'cpinfo -y all'Verify Fix Applied:
After applying the hotfix, verify that TLS certificate validation occurs during CSV downloads by checking system logs for successful secure connections.📡 Detection & Monitoring
Log Indicators:
- Failed CSV downloads
- Unexpected country flag displays in logs
- TLS certificate validation errors in download logs
Network Indicators:
- Unencrypted CSV file downloads
- Man-in-the-middle attacks targeting CSV download endpoints
SIEM Query:
Search for failed CSV download attempts or unexpected modifications to IP-to-country mapping files in system logs.
