Name of the Vulnerable Software and Affected Versions zephyr version 2.1.0 and later versions
Description The issue concerns the UpdateHub module, which disables DTLS peer checking. This allows for a man-in-the-middle attack. However, firmware images require valid signatures, mitigating the issue to some extent. It's noted that there's no benefit to using DTLS without peer checking.
Recommendations For zephyr version 2.1.0 and later versions, consider disabling the UpdateHub module until a patch is available that enables DTLS peer checking. As a mitigation measure, ensure that all firmware images are properly signed to minimize the risk of exploitation.
