In updatehub_probe, right after JSON parsing is complete, objects\[1] is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an information leak. Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server.

The UpdateHub module disables DTLS peer checking, which allows for a man in the middle attack. This is mitigated by firmware images requiring valid signatures. However, there is no benefit to using DTLS without the peer checking. See NCC-ZEP-018 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. El módulo UpdateHub deshabilita la comprobación del peer DTLS, lo que permite un ataque de tipo man in the middle. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10059 https://github.com/zephyrproject-rtos/zephyr/pull/24954 https://github.com/zephyrproject-rtos/zephyr/pull/24997 https://github.com/zephyrproject-rtos/zephyr/pull/24999 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-36 • CWE-295: Improper Certificate Validation •
