Vulnerability from github – Published: 2022-05-24 16:58 – Updated: 2022-11-02 19:00

Details

Amazon FreeRTOS up to and including v1.4.8 for AWS lacks length checking in prvProcessReceivedPublish, resulting in leakage of arbitrary memory contents on a device to an attacker. An attacker sends a malformed MQTT publish packet, and waits for an MQTTACK packet containing the leaked data.

Severity ?

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

CVE-2019-13120 (GCVE-0-2019-13120)

Vulnerability from cvelistv5 – Published: 2019-10-07 21:57 – Updated: 2024-08-04 23:41

Summary

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.

Severity ?

No CVSS data available.
