CVE-2020-10059: Zephyrproject Zephyr

Medium severity, CVSS 4.8. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

Affected products

• Zephyrproject Zephyr: version 2.1.0 only; version 2.2.0 only
