VAR-201804-1729

Vulnerability from variot - Updated: 2022-05-04 10:08

RS485 Temperature and Humidity Recorder / Temperature and Humidity Controller This transmitter is widely used in communication rooms, warehouse buildings, and self-control places that require temperature and humidity monitoring. The input power, temperature measurement unit and signal output of the sensor are completely isolated.

There is a loophole in the logic design of the Jianda Renke 485 device. An attacker can use the attacker to impersonate the 485 device and preemptively respond to the counterfeit data of the host's query command.
