CVE-2022-29060
📋 TL;DR
This vulnerability involves hard-coded cryptographic keys in FortiDDoS API versions 5.5.0 through 5.5.1, 5.4.0 through 5.4.2, 5.3.0 through 5.3.1, 5.2.0, and 5.1.0. An attacker who obtains the key from one device can forge JWT tokens to impersonate any device, potentially gaining unauthorized access to the API. Organizations using affected FortiDDoS versions are at risk.

⚠️ Risk & Real-World Impact
Worst Case
An attacker gains full administrative control over the FortiDDoS system, allowing them to disable DDoS protection, modify configurations, exfiltrate sensitive data, or use the device as a pivot point into the network.
Likely Case
Attackers forge JWT tokens to bypass authentication and gain unauthorized API access, potentially extracting configuration data or disrupting DDoS protection services.
If Mitigated
With proper network segmentation and API access controls, impact is limited to the FortiDDoS management interface without lateral movement into the broader network.
🎯 Exploit Status
Exploitation requires obtaining the hard-coded key first, which may involve other vulnerabilities or access to a compromised device.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: FortiDDoS 5.5.2, 5.4.3, 5.3.2, 5.2.1, 5.1.1
Vendor Advisory: https://fortiguard.com/psirt/FG-IR-22-071
Restart Required: Yes
Instructions:
1. Download the appropriate firmware version from Fortinet support portal. 2. Backup current configuration. 3. Apply firmware update via web interface or CLI. 4. Reboot the device. 5. Verify the update was successful.
🔧 Temporary Workarounds
Restrict API Access
allLimit network access to the FortiDDoS API interface to only trusted management IP addresses.
Configure firewall rules to restrict access to FortiDDoS management IP/port
Disable Unused API Features
allDisable any API endpoints or features that are not required for operations.
Review and disable unnecessary API services in FortiDDoS configuration
🧯 If You Can't Patch
- Isolate FortiDDoS management interface on a separate VLAN with strict access controls.
- Implement network monitoring for unusual API authentication patterns or JWT token usage.
🔍 How to Verify
Check if Vulnerable:
Check FortiDDoS firmware version via web interface (System > Dashboard) or CLI command 'get system status'.Check Version:
get system statusVerify Fix Applied:
Verify firmware version is 5.5.2, 5.4.3, 5.3.2, 5.2.1, or 5.1.1 or later.📡 Detection & Monitoring
Log Indicators:
