Systems Affected

All LANTIME firmware versions before 7.10.005 are affected by the corresponding vulnerabilities. The LANTIME firmware is used by all devices of the LANTIME M series (M100, M150, M200, M250, M300, M320, M400, M450, 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, SF1500) and LANTIME CPU Expansions (LCES).

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.

Possible Security Measures

The relevant security updates are included in the LANTIME firmware versions 7.10.006. Updating to these versions eliminates the listed vulnerabilities.
