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.
