Description
Some Dahua software products have a vulnerability of unauthenticated request of MQTT credentials. An attacker can obtain encrypted MQTT credentials by sending a specific crafted packet to the vulnerable interface (the credentials cannot be directly exploited).
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 0.6% probability of exploitation activity in the next 30 days.
