Honeywell CCTV products found vulnerable to unauthenticated access (CVE-pending). Learn mitigation steps for security teams.

Critical Authentication Bypass in Honeywell CCTV Systems Discovered

Madrid, Spain – February 18, 2026 – Security researchers at INCIBE-CERT have identified a severe authentication flaw in select Honeywell closed-circuit television (CCTV) products, potentially allowing unauthenticated attackers to gain access to sensitive surveillance systems and connected networks.

Technical Details of the Vulnerability

The vulnerability stems from a lack of authentication mechanisms in certain Honeywell CCTV devices. Attackers with network access to affected systems could exploit this flaw to:

  • Bypass authentication entirely
  • Gain unauthorized access to live video feeds
  • Potentially pivot to other networked systems

At the time of disclosure, no CVE identifier has been assigned to this vulnerability. INCIBE-CERT has classified the flaw as high severity due to its potential impact on critical infrastructure security.

Impact Analysis

This vulnerability poses significant risks to organizations relying on Honeywell CCTV systems for physical security:

  • Unauthorized surveillance: Attackers could monitor sensitive areas without detection
  • Network infiltration: Compromised CCTV systems could serve as entry points to broader corporate networks
  • Compliance violations: Unauthorized access may violate data protection regulations (e.g., GDPR, NIS2)

Security teams should note that exploitation requires network-level access to vulnerable devices, either through local networks or exposed internet-facing interfaces.

Mitigation Recommendations

INCIBE-CERT advises the following immediate actions:

  1. Network segmentation: Isolate CCTV systems from corporate networks using VLANs or dedicated security zones
  2. Access controls: Implement strict firewall rules to restrict access to CCTV management interfaces
  3. Monitoring: Deploy intrusion detection systems (IDS) to detect unusual access patterns
  4. Patch management: Apply Honeywell security updates immediately upon release
  5. Audit: Review all CCTV system configurations for unauthorized changes

Honeywell has been notified of this vulnerability and is expected to release patches shortly. Organizations using Honeywell CCTV products should monitor the vendor's security advisories for updates and apply fixes without delay.
