Weakness (CWE)
CWE-1329: Reliance on Component That is Not Updateable
The product contains a component that cannot be updated or patched in order to remove vulnerabilities or significant bugs.
More detail
If the component is discovered to contain a vulnerability or critical bug, but the issue cannot be fixed using an update or patch, then the product's owner will not be able to protect against the issue. The only option might be replacement of the product, which could be too financially or operationally expensive for the product owner. As a result, the inability to patch or update can leave the product open to attacker exploitation or critical operation failures. This weakness can be especially difficult to manage when using ROM, firmware, or similar components that traditionally have had limited or no update capabilities.
In industries such as healthcare, "legacy"
devices can be operated for decades. As a
US task force report [REF-1197] notes, "the inability
to update or replace equipment has both
large and small health care delivery
organizations struggle with numerous
unsupported legacy systems that cannot
easily be replaced (hardware, software, and
operating systems) with large numbers of
vulnerabilities and few modern
countermeasures."
While hardware can be prone to this weakness, software systems can also be affected, such as when a third-party driver or library is no longer actively maintained or supported but is still critical for the required functionality.
How to prevent it (4 mitigations)
-
Requirements
Specify requirements that each component should be updateable, including ROM, firmware, etc.
-
Architecture and Design
Design the product to allow for updating of its components. Include the external infrastructure that might be necessary to support updates, such as distribution servers.
-
Architecture and Design, Implementation
With hardware, support patches that can be programmed in-field or during manufacturing through hardware fuses. This feature can be used for limited patching of devices after shipping, or for the next batch of silicon devices manufactured, without changing the full device ROM.
-
Implementation
Implement the necessary functionality to allow each component to be updated.
