CVE-2026-85628 Fermax Electronica S.A.U. CVE debrief

Who should care

Defenders responsible for Wi-Fi network security, particularly those using DuoxMe application and VEO and VEO-XS Wi-Fi monitors, should assess exposure and prioritize upgrading to version 4.3.4 of the application and 01.50.001 of the monitor firmware or later.

Why it matters

CVE-2026-85628 allows an attacker on the Wi-Fi Direct network to intercept home Wi-Fi credentials during pairing of DuoxMe application and VEO and VEO-XS Wi-Fi monitors. Defenders should verify exposure, prioritize upgrading, and monitor for suspicious activity.

• Verify exposure of Wi-Fi networks to credential interception
• Upgrade to secure version to prevent credential interception
• Monitor Wi-Fi Direct network for suspicious activity

Technical summary

The DuoxMe application and VEO and VEO-XS Wi-Fi monitors transmit home Wi-Fi credentials without encryption during pairing. This vulnerability allows an attacker on the Wi-Fi Direct network to intercept the network password. The issue affects versions prior to 4.3.4 of the application and 01.50.001 of the monitor firmware. Defenders should prioritize verifying exposure of Wi-Fi networks using these devices and upgrading to secure versions to prevent credential interception. Upgrades to version 4.3.4 of the application and 01.50.001 of the monitor firmware or later are recommended.

Defensive priority

Defenders should prioritize verifying exposure of Wi-Fi networks using DuoxMe application and VEO and VEO-XS Wi-Fi monitors, and upgrading to version 4.3.4 of the application and 01.50.001 of the monitor firmware or later.

Recommended defensive actions

• Verify exposure of Wi-Fi networks using DuoxMe application and VEO and VEO-XS Wi-Fi monitors
• Upgrade to version 4.3.4 of the application and 01.50.001 of the monitor firmware or later
• Monitor Wi-Fi Direct network for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
