CVE-2026-2624
📋 TL;DR
This critical vulnerability allows attackers to bypass authentication mechanisms in ePati Antikor Next Generation Firewall (NGFW), potentially gaining unauthorized administrative access. It affects all systems running vulnerable versions of the firewall software. Organizations using affected versions are at immediate risk of compromise.
💻 Affected Systems
- ePati Cyber Security Technologies Inc. Antikor Next Generation Firewall (NGFW)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete firewall compromise allowing attackers to reconfigure security policies, intercept network traffic, disable security controls, and pivot to internal networks.
Likely Case
Unauthorized administrative access leading to firewall rule manipulation, network traffic monitoring, and potential lateral movement into protected networks.
If Mitigated
Limited impact if firewall is isolated with strict network segmentation and additional authentication layers, though core functionality remains vulnerable.
🎯 Exploit Status
Authentication bypass vulnerabilities typically require minimal technical skill to exploit once the attack vector is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v.2.0.1301
Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-26-0082
Restart Required: Yes
Instructions:
1. Download v.2.0.1301 from vendor portal. 2. Backup current configuration. 3. Apply update through admin interface. 4. Reboot firewall. 5. Verify version and functionality.
🔧 Temporary Workarounds
Network Isolation
allRestrict management interface access to trusted IP addresses only
Configure firewall rules to allow management access only from specific administrative subnets
Multi-factor Authentication
allImplement additional authentication layer for management access
Configure RADIUS/TACACS+ with MFA for admin authentication
🧯 If You Can't Patch
- Immediately isolate firewall management interface from untrusted networks
- Implement network monitoring for unusual authentication attempts or configuration changes
🔍 How to Verify
Check if Vulnerable:
Check firewall version in admin interface: System > About > VersionCheck Version:
Check via admin interface or SSH: show versionVerify Fix Applied:
Confirm version shows v.2.0.1301 or later in admin interface📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful login from same IP
- Configuration changes from unexpected IP addresses
- Admin login from non-standard locations
Network Indicators:
- Unusual management interface traffic patterns
- Authentication requests bypassing normal flow
