This vulnerability occurs when a system lacks password expiration policies, allowing users to keep the same password indefinitely.
Password aging, also known as password rotation, is a security policy that requires users to update their passwords after a set period, such as every 30 or 90 days. Without this enforcement, users may never change their credentials, leaving accounts vulnerable if a password is ever compromised. While once a standard recommendation, mandatory password rotation is now considered less effective against modern threats compared to strong, slow hashing algorithms and multi-factor authentication. Forcing frequent changes can lead to weaker password choices and user frustration. However, many organizations still implement it to meet specific compliance requirements, such as PCI DSS standards for handling payment card data.
Impact: Gain Privileges or Assume Identity
As passwords age, the probability that they are compromised grows.
Effectiveness: Discouraged Common Practice
