CWE-1277: 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.
How it's found
Firmware Not Updateable is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
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.
Vulnerable vs. safe
The refrigerator has no means of patching and is hacked, becoming a spewer of email spam.The device automatically patches itself and provides considerable more protection against being hacked.Consequences
- Gain Privileges or Assume Identity, Bypass Protection Mechanism, Execute Unauthorized Code or Commands, DoS: Crash, Exit, or Restart: If an attacker can identify an exploitable vulnerability in one device that has no means of patching, the attack may be used against an entire class of devices.
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.
Where this fits in a TurboPentest engagement
TurboPentest's agentic pentest is powerful and covers a broad range of issues automatically. This particular class is best confirmed in a manual IntegSec engagement, where human pentesters apply deeper methodology and a larger context window than any automated pass.
