CWE-262: Not Using Password Aging

Weakness ID: 262
Abstraction: Base
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
If no mechanism is in place for managing password aging, users will have no incentive to update passwords in a timely manner.
+ Extended Description
Security experts have often recommended that users change their passwords regularly and avoid reusing passwords. Although this can be an effective mitigation, if the expiration window is too short, it can cause users to generate poor or predictable passwords. As such, it is important to discourage creating similar passwords. It is also useful to have a password aging mechanism that notifies users when passwords are considered old and requests that they replace them with new, strong passwords. Companion documentation which stresses how important this practice is can help users understand and better support this approach.
+ 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.

NatureTypeIDName
ChildOfClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.404Improper Resource Shutdown or Release
ChildOfClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.287Improper Authentication
PeerOfBaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.263Password Aging with Long Expiration
PeerOfBaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention.

+ Modes Of Introduction

The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

PhaseNote
Architecture and DesignCOMMISSION: 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.

Languages

Class: Language-Independent (Undetermined Prevalence)

+ Common Consequences

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.

ScopeImpactLikelihood
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 system does not enforce the changing of passwords every certain period.

+ Potential Mitigations

Phase: Architecture and Design

As part of a product's design, require users to change their passwords regularly and avoid reusing previous passwords.
