CVE-2025-9290
📋 TL;DR
This vulnerability allows attackers to intercept adoption traffic between Omada network devices and forge authentication through offline precomputation attacks. It affects Omada Controllers, Gateways, and Access Points during the device adoption process. Attackers could potentially gain unauthorized access to sensitive information.
💻 Affected Systems
- Omada Controllers
- Omada Gateways
- Omada Access Points
⚠️ 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.

⚠️ Risk & Real-World Impact
Worst Case
Complete network compromise allowing attacker to intercept all adoption traffic, forge authentication to join devices to malicious controllers, and access sensitive network configuration data.
Likely Case
Targeted attacks against specific organizations where attackers can position themselves to intercept adoption traffic, potentially gaining access to network management interfaces.
If Mitigated
Limited impact if adoption traffic is encrypted and isolated, with attackers unable to achieve network positioning required for interception.
🎯 Exploit Status
Exploitation requires advanced network positioning to intercept adoption traffic and significant computational resources for offline precomputation attacks.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://support.omadanetworks.com/us/document/114950/
Restart Required: Yes
Instructions:
1. Check current firmware version. 2. Download latest firmware from Omada support site. 3. Backup configuration. 4. Apply firmware update. 5. Restart affected devices. 6. Verify adoption process uses updated authentication mechanisms.
🔧 Temporary Workarounds
Isolate Adoption Traffic
allPerform device adoption on isolated network segments to prevent interception
Physical Adoption Only
allPerform device adoption using direct physical connections rather than over network
🧯 If You Can't Patch
- Isolate adoption network segments using VLANs or physical separation
- Monitor network traffic for unusual adoption patterns or unauthorized adoption attempts
🔍 How to Verify
Check if Vulnerable:
Check if devices are running vulnerable firmware versions by reviewing version information in Omada controller interfaceCheck Version:
Check version in Omada controller web interface under System > About or via SSH using appropriate device-specific commandsVerify Fix Applied:
Verify firmware has been updated to patched version and test adoption process with network monitoring📡 Detection & Monitoring
Log Indicators:
- Multiple failed adoption attempts
- Unusual adoption traffic patterns
- Devices adopting from unexpected IP addresses
Network Indicators:
- Unencrypted adoption traffic on network
- Adoption packets from unauthorized sources
- Suspicious precomputation traffic patterns
