What is CVE-2019-13120?

Amazon FreeRTOS, in versions up to and including v1.4.8, suffers from a memory leak vulnerability due to inadequate length validation in the function responsible for processing incoming MQTT publish messages. This flaw allows an attacker, who has the necessary authorization to send a malformed MQTT packet, to potentially expose arbitrary memory contents from the device. Such exposure could lead to unauthorized data access, particularly if the device interacts with an affected MQTT message. The vulnerability highlights the importance of strict input validation to secure IoT devices.
