The SIMA2 Master Station features an NTP service based on ntpd, a reference implementation of the Network Time Protocol (NTP). Affected SIMA2 Master Stations with software version < V2.6 include an outdated version of ntpd which is affected by a large number of vulnerabilities
Improper buffer restrictions in the webserver used in SIMA² Master Station software versions < V 2.6 may allow an unauthenticated network-based attacker to stop the cyclic program on the device and cause a denial of service.
