CWE-263: Password Aging with Long Expiration
Weakness ID : 263
Structure : Simple
Abstraction : Base
Description
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).
