Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the MQTT and Greengrass discovery modules of FreeRTOS due to MQTT agent and GGD modules misuse the API of mbedTLS, creating a corrupt mbedTLS context object. A remote attacker can execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
