CWE-1277

Firmware Not Updateable

Base
Draft

Description

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.

Common Consequences

Scope

Confidentiality
Integrity
Access Control
Authentication
Authorization

Impact

Gain Privileges or Assume Identity, Bypass Protection Mechanism, Execute Unauthorized Code or Commands, DoS: Crash, Exit, or Restart

Potential Mitigations

Requirements

Specify requirements to include the ability to update the firmware. Include integrity checks and authentication to ensure that untrusted firmware cannot be installed.

Architecture and Design

Design the device to allow for updating the firmware. Ensure that the design specifies how to distribute the updates and ensure their integrity and authentication.

Implementation

Implement the necessary functionality to allow the firmware to be updated.

CVE-2020-9054

Chain: network-attached storage (NAS) device has a critical OS command injection (CWE-78) vulnerability that is actively exploited to place IoT devices into a botnet, but some products are "end-of-support" and cannot be patched (CWE-1277). [REF-1097]

[REF-1095]

A hardware "smart lock" has weak key generation that allows attackers to steal the key by BLE sniffing, but the device's firmware cannot be upgraded and hence remains vulnerable [REF-1095].
