CWE-324Use of a Key Past its Expiration Date

Abstraction: Base · CVEs in our corpus: 22

The product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key.

While the expiration of keys does not necessarily ensure that they are compromised, it is a significant concern that keys which remain in use for prolonged periods of time have a decreasing probability of integrity. For this reason, it is important to replace keys within a period of time proportional to their strength.

NIST 800-53 r5 controls PROPOSED for this weakness (1)AI-assisted

These are model PROPOSALS, not graded mappings. They come from controls_to_cwe_proposals, which carries no grade field at all; across the CWE pages 1,540 of 1,722 such associations (89%) have never been graded by anything. The heading said “address” until 2026-09-29, which asserted a relationship the data does not carry. Graded cross-walks are on the framework map, not here.

Control	Title	Family	Why it addresses this CWE
`SC-12`	Cryptographic Key Establishment and Management	SC	graded full Key-management requirements enforce lifecycle controls that prevent continued use of expired or superseded keys.
