Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the MQTT packet parsing functionality due to improper input validation. A remote attacker can send a specially crafted MQTT packet over network to cause an arbitrary out-of-bounds memory read and write potentially resulting in information disclosure, denial of service and remote code execution.
Successful exploitation of the vulnerability may result in system compromise.
