DuoxMe: Cleartext Transmission of Sensitive Information
CVE-2026-85628 is a high-severity cleartext transmission of sensitive information vulnerability in DuoxMe from Fermax Electronica S.A.U., with a CVSS 4.0 base score of 7.0 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 4.3.4 as the first without the flaw, so updating DuoxMe to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.09% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update DuoxMe to 4.3.4 or a later version.
- Update DUOX PLUS monitor firmware (VEO Wi-Fi range) to 01.50.001 or a later version.
- Read the advisory on fermax.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Fermax Electronica S.A.U. | DuoxMe | before 4.3.4 | 4.3.4 |
| Fermax Electronica S.A.U. | DUOX PLUS monitor firmware (VEO Wi-Fi range) | before 01.50.001 | 01.50.001 |

Official description
Transmission of the home Wi-Fi credentials without encryption during the pairing process between the DuoxMe application and VEO and VEO-XS Wi-Fi monitors, in versions prior to 4.3.4 of the application and 01.50.001 of the monitor firmware, allows an attacker on the Wi-Fi Direct network to intercept the network password.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
