Allowing password aging to occur unchecked can result in the possibility of diminished password integrity.
Extended Description
Just as neglecting to include functionality for the management of password aging is dangerous, so is allowing password aging to continue unchecked. Passwords must be given a maximum life span, after which a user is required to update with a new and different password.
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, MemberOf 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 the user may want to explore.

Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More general than a Base weakness.
Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More general than a Base weakness.
Variant - a weakness that is described at a very low level of detail, typically limited to a specific language or technology. More specific than a Base weakness.
The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the software life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

Architecture and Design
COMMISSION: This weakness refers to an incorrect design related to an architectural security tactic.
Applicable Platforms
The listings below show possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.
The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.
Scope
Impact
Likelihood
Access Control
Technical Impact: Gain Privileges or Assume Identity
As passwords age, the probability that they are compromised grows.
Likelihood Of Exploit
Low
Demonstrative Examples
Example 1
A common example is not having a system to terminate old employee accounts.
Example 2
Not having a system for enforcing the changing of passwords every certain period.
Potential Mitigations
Phase: Architecture and Design
Ensure that password aging is limited so that there is a defined maximum age for passwords and so that the user is notified several times leading up to the password expiration.
