The product supports password aging, but the expiration period is too long.
Extended Description
Password aging (or password rotation) is a policy that forces users to change their passwords after a defined time period passes, such as every 30 or 90 days. A long expiration provides more time for attackers to conduct password cracking before users are forced to change to a new password.
Note that while password aging was once considered an important security feature, it has since fallen out of favor by many, because it is not as effective against modern threats compared to other mechanisms such as slow hashes. In addition, forcing frequent changes can unintentionally encourage users to select less-secure passwords. However, password aging is still in use due to factors such as compliance requirements, e.g., Payment Card Industry Data Security Standard (PCI DSS).

Class - 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.

Applicable Platforms
This listing shows 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.

Common Consequences
This table 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.

Technical Impact: Gain Privileges or Assume Identity
As passwords age, the probability that they are compromised grows.

Demonstrative Examples
Example 1
A system requires the changing of passwords every five years.
Potential Mitigations
Phase: Architecture and Design
Ensure that password aging is limited so that there is a defined maximum age for passwords. Note that if the expiration window is too short, it can cause users to generate poor or predictable passwords.
Phase: Architecture and Design
Ensure that the user is notified several times leading up to the password expiration.
Phase: Architecture and Design
Create mechanisms to prevent users from reusing passwords or creating similar passwords.
Phase: Implementation
Developers might disable clipboard paste operations into password fields as a way to discourage users from pasting a password into a clipboard. However, this might encourage users to choose less-secure passwords that are easier to type, and it can reduce the usability of password managers [REF-1294].
