CWE-920: Improper Restriction of Power Consumption

Weakness ID: 920
Abstraction: Base
Status: Incomplete
Presentation Filter:
+ Description

Description Summary

The software operates in an environment in which power is a limited resource that cannot be automatically replenished, but the software does not properly restrict the amount of power that its operation consumes.

Extended Description

In environments such as embedded or mobile devices, power can be a limited resource such as a battery, which cannot be automatically replenished by the software itself, and the device might not always be directly attached to a reliable power source. If the software uses too much power too quickly, then this could cause the device (and subsequently, the software) to stop functioning until power is restored, or increase the financial burden on the device owner because of increased power costs.

Normal operation of an application will consume power. However, in some cases, an attacker could cause the application to consume more power than intended, using components such as:

  • Display

  • CPU

  • Disk I/O

  • GPS

  • Sound

  • Microphone

  • USB interface

+ Time of Introduction
  • Architecture and Design
+ Applicable Platforms



Architectural Paradigms

Mobile Application

+ Common Consequences

Technical Impact: DoS: resource consumption (other); DoS: crash / exit / restart

The power source could be drained, causing the application - and the entire device - to cease functioning.
