Fix

  1. Mitigation from the vendor CISA ICSA-21-208-03 · 6 productsGeutebrück strongly recommends updating all affected cameras and encoders listed above to firmware Version 1.12.14.7 or later. The security advisory and the latest firmware can both be acquired on Geutebrück's web portal (Login required).
  2. Mitigation from the vendor CISA ICSA-21-208-03 · 6 productsIf updates cannot be deployed, Geutebrück recommends taking the following defensive measures to minimize the risk of exploitation of these vulnerabilities:
  3. Mitigation from the vendor CISA ICSA-21-208-03 · 6 productsChange the default passwords of the cameras.
  4. Mitigation from the vendor CISA ICSA-21-208-03 · 6 productsMinimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
  5. Mitigation from the vendor CISA ICSA-21-208-03 · 6 productsLocate control system networks and remote devices behind firewalls and isolate them from the business network.
  6. Mitigation from the vendor CISA ICSA-21-208-03 · 6 productsWhen remote access is required, use secure methods, such as virtual private networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
