CVE-2026-79391
UnknownSummary
The MQTT service in Trueview 6.0.23.4 has no authentication. The MQTT broker accepts client connections on TCP port 1883 without requiring authentication, allowing a remote attacker with network access to establish an MQTT session and perform unauthorized publish or subscribe operations.
Risk Assessment
An attacker can take control of MQTT communication, publish false data, or eavesdrop on sensitive information, potentially leading to data integrity and confidentiality breaches.
Recommendation
Enable authentication on the MQTT broker and restrict access to port 1883 to trusted devices only.

Trueview TI8161 6.0.23.4 is vulnerable to information disclosure due to transmission of MQTT communications in plaintext over TCP port 1883. An unauthenticated attacker with access to the same network segment can intercept MQTT traffic and obtain sensitive device information and operational data, including device identifiers, message metadata, and control-related information.
- CVE-2026-79389Unknown
