Firmware Not Updateable
The product does not provide its users with the ability to update or patch its firmware to address any vulnerabilities or weaknesses that may be present.
Without the ability to patch or update firmware, consumers will be left vulnerable to exploitation of any known vulnerabilities, or any vulnerabilities that are discovered in the future. This can expose consumers to permanent risk throughout the entire lifetime of the device, which could be years or decades. Some external protective measures and mitigations might be employed to aid in preventing or reducing the risk of malicious attack, but the root weakness cannot be corrected.
The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.
Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.
A refrigerator has an Internet interface for the official purpose of alerting the manufacturer when that refrigerator detects a fault. Because the device is attached to the Internet, the refrigerator is a target for hackers who may wish to use the device other potentially more nefarious purposes.
Weaknesses in this category can arise in multiple areas of hardware design or can apply to a wide cross-section of components.
