On Friday, December 10, 2021, the Apache Software Foundation announced a critical security vulnerability in its "Log4j" software. Due to the wide distribution of this software, the disclosure was widely reported in the media. Log4j is an open source software component widely distributed on the Internet and used by the largest companies in the world. However, after a detailed review by the MOBOTIX cyber security team, it is clear that users of MOBOTIX hardware and software products, including the MOBOTIX HUB, ManagementCenter and CLOUD video management systems, do not need to take any action on their network systems. We will continue to track updates and announcements from official sources.
