Last modified
CVE-2019-13120 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Amazon FreeRTOS up to and including v1.4.8 lacks length checking in prvProcessReceivedPublish, resulting in untargetable leakage of arbitrary memory contents on a device to an attacker. If an attacker has the authorization to send a malformed MQTT publish packet to an Amazon IoT Thing, which interacts with an associated vulnerable MQTT message in the application, specific circumstances could trigger this vulnerability.. EPSS estimates a 1.19% chance of exploitation in the next 30 days.
