2. Systems Affected

   All LANTIME Firmware Versions before V7.04.017 or V6.24.032 respectively are affected by the corresponding vulnerabilities. The LANTIME Firmware is used by all devices of the LANTIME M Series (M100, M200, M300, M400, M600, M900) as well as all devices of the LANTIME IMS Series (M500, M1000, M1000S, M2000S, M3000, M3000S, M4000) and the SyncFire product family (SF1000 / SF1100 / SF1200).

   Whether and to what extent individual clients or LANTIME systems are vulnerable depends on the individual configuration, network infrastructure, and other factors, and it is therefore not possible to provide a general statement on how vulnerable a given system in use actually is.

3. Possible Security Measures

   The relevant Security Updates are included in the LANTIME Firmware Versions V7.04.017 and V6.24.032. Updating to these versions eliminates the listed vulnerabilities.
