Technical Analysis
CVE-2026-79391 describes a lack of authentication in the MQTT broker service of Trueview 6.0.23.4. The broker accepts client connections on TCP port 1883 without requiring any authentication, enabling remote attackers who have network access to establish MQTT sessions and carry out unauthorized publish or subscribe operations. This represents a critical security flaw that compromises confidentiality, integrity, and availability of the MQTT messaging service.
Potential Impact
An attacker can remotely connect to the MQTT broker without credentials and perform unauthorized publish or subscribe operations. This can lead to unauthorized data access, injection of malicious messages, or disruption of service, impacting confidentiality, integrity, and availability of the MQTT communication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the MQTT service (TCP port 1883) to trusted hosts only and consider deploying network-level controls to prevent unauthorized connections.
