Remediations
Vendor fixTo help reduce the risk of exploitation, Johnson Control suggests considering the following defensive measures: Apply firmware update 5.63. MitigationJohnson 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. MitigationMonitor device access logs for any anomalous authentication activity. MitigationRotate any shared or downstream credentials that may have been derived from or associated with the hard-coded values. MitigationImplement network segmentation and place ICS/SCADA devices and systems behind firewalls, isolating them from the business network. MitigationWhen 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.
MitigationMinimize network exposure for all control system devices and/or systems; ensure they are not accessible from the internet. MitigationConduct regular firmware integrity checks to detect unauthorizedmodifications.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices
on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability has a high attack complexity.
