FragAttacks - WiFi Fregmentation and Aggregation Attacks
At this time, Digi is still reviewing these attacks and how they impact our devices. From the nature of the attacks, we do expect that Digi devices will be impacted.
However, it is critical to note that even with these attacks, it has always been DIgi's policy and suggestions that network communication should never rely on the protections and standards of the data layers (WiFi/BlueTooth). Many of these are implemented in HW and can be difficult to change. If good network practices are used, (TLS/Certificates etc), then these vulnerabilities do not lead to any real impact. These vulnerabilites can only become impactful IF other flaws or issues are present.
It is Digi's intent to address these issues so that we preserve our defense in depth strategy to security in our products. Due to the complexity of these issues, we believe we will be able to address these by Q4 of 2021 or sooner if possible.
