CWE-1272: Sensitive Information Uncleared Before Debug/Power State
Transition
Weakness ID : 1272
Structure : Simple
Abstraction : Base
Description
The product performs a power or debug state transition, but it does not clear sensitive information
that should no longer be accessible due to changes to information access restrictions.
Extended Description
A device or system frequently employs many power and sleep states during its normal operation
(e.g., normal power, additional power, low power, hibernate, deep sleep, etc.). A device also may
be operating within a debug condition. State transitions can happen from one power or debug state
to another. If there is information available in the previous state which should not be available in the
next state and is not properly removed before the transition into the next state, sensitive information
may leak from the system.
Relationships
The table(s) below shows the weaknesses and high level categories that are related to this
weakness. These relationships are defined as ChildOf, ParentOf, MemberOr and give insight to
similar items that may exist at higher and lower levels of abstraction. In addition, relationships such
as PeerOf and CanAlsoBe are defined to show similar weaknesses that may want to be explored.
