CVE-2026-8173
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
The web GUI of affected Murrelektronik Xelity switches logs MAC addresses from the devices MAC address table when an authenticated administrator uses the 'Copy learned MAC Addresses' function. Due to improper generation of error messages, an unauthenticated attacker with network access to the web interface can retrieve the logged MAC addresses via browser developer tools.
Risk Assessment
Disclosure of MAC addresses can help an attacker map the network and conduct further attacks such as spoofing or privacy breaches.
Recommendation
Restrict access to the web interface to trusted networks only and consider updating the firmware if a patch is available.
