Risk Evaluation

An information disclosure vulnerability in the web GUI of Murrelektronik Xelity switches causes MAC addresses from the device's MAC address table to be written into a server-side log that is exposed via the device's web interface to unauthenticated users. The leak is triggered when an authenticated administrator invokes the 'Copy learned MAC Addresses' function, which causes a syslog error that inserts the affected MAC addresses into the log output. Once the error has been triggered, any unauthenticated attacker with network access to the web interface can retrieve the leaked MAC addresses via common browser developer tools. The vulnerable functionality was introduced in version 2.1.0 and is fixed in version 2.1.1.

Zusammenfassung der Gegenmaßnahmen

Update the affected Xelity switches to firmware version V2.1.1 or later. This firmware version removes the syslog error that caused the MAC address table contents to be written to a web-accessible log.
