Product Version: Johnson Controls Inc. TL280: <5.63 Product Status: known_affected Remediations Vendor fix To help reduce the risk of exploitation, Johnson Control suggests considering the following defensive measures: Apply firmware update 5.63. Mitigation Johnson Controls suggests the following defensive measures: Restrict network access to affected cameras to trusted management VLANs only - do not expose these devices directly to the internet or untrusted network segments. Mitigation Monitor device access logs for any anomalous authentication activity. Mitigation Rotate any shared or downstream credentials that may have been derived from or associated with the hard-coded values. Mitigation Implement network segmentation and place ICS/SCADA devices and systems behind firewalls, isolating them from the business network. Mitigation When remote access is required, use secure methods such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be kept up to date.
