CWE-262: Not Using Password Aging

Weakness ID: 262
Abstraction: Variant
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.
+ 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.

+ 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 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

The recommendation that users change their passwords regularly and do not reuse passwords is universal among security experts. In order to enforce this, it is useful to have a password aging mechanism that notifies users when passwords are considered old and that requests that they replace them with new, strong passwords. In order for this functionality to be useful, however, it must be accompanied with documentation which stresses how important this practice is and which makes the entire process as simple as possible for the user.
+ Memberships
This MemberOf Relationships table shows additional CWE Categories and Views that reference this weakness as a member. This information is often useful in understanding where a weakness fits within the context of external information sources.
