CVE-2025-24525
📋 TL;DR
Keysight Ixia Vision devices contain hardcoded cryptographic material that could allow attackers to intercept or decrypt API calls and user authentication traffic. This affects all users who haven't replaced the default TLS certificate shipped with the device. The vulnerability stems from using predictable or known cryptographic keys in the device's default configuration.

⚠️ 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).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could decrypt all sensitive communications including administrative credentials, configuration data, and monitoring traffic, potentially gaining full control of the device and using it as a foothold into the network.
Likely Case
Attackers with network access could intercept and decrypt API traffic, potentially obtaining administrative credentials and manipulating device configuration or test results.
If Mitigated
With proper certificate replacement before deployment, the risk is eliminated as the hardcoded material is no longer in use.
🎯 Exploit Status
Exploitation requires network access to intercept traffic but doesn't require authentication. The hardcoded nature of the cryptographic material makes exploitation straightforward once the material is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.9.1
Vendor Advisory: https://support.ixiacom.com/
Restart Required: Yes
Instructions:
1. Download version 6.9.1 from Keysight support portal. 2. Backup current configuration. 3. Apply the update following vendor instructions. 4. Replace the default TLS certificate with a unique, properly generated certificate. 5. Restart the device to apply changes.
🔧 Temporary Workarounds
Replace Default TLS Certificate
allGenerate and install a new, unique TLS certificate to replace the hardcoded default certificate
# Generate new certificate (example for OpenSSL)
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
# Follow vendor documentation to install the new certificate
Network Segmentation
allIsolate Ixia Vision devices from untrusted networks and limit API access to authorized management systems only
# Configure firewall rules to restrict access
# Example: Only allow specific source IPs to connect to Ixia Vision API ports
🧯 If You Can't Patch
- Immediately replace the default TLS certificate with a unique certificate generated specifically for your deployment
- Implement strict network access controls to limit which systems can communicate with the Ixia Vision device, preferably placing it in a management VLAN with limited access
🔍 How to Verify
Check if Vulnerable:
Check if the device is using the default TLS certificate by examining the certificate details and comparing with known default certificate fingerprints or checking if the device version is below 6.9.1Check Version:
Check the web interface or administrative console for version information, or use vendor-specific CLI commands if availableVerify Fix Applied:
Verify the device is running version 6.9.1 or later and confirm that a unique TLS certificate (not the default) is installed and in use📡 Detection & Monitoring
