CWE-324Use of a Key Past its Expiration Date

Abstraction: Base · CVEs in our corpus: 20

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 that address this weakness (1)AI

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and ManagementSCKey-management requirements enforce lifecycle controls that prevent continued use of expired or superseded keys.

MITRE ATT&CK techniques this weakness enables

Our own two-way CWE↔ATT&CK cross-walk — a direct mapping with no public source (the CWE→CAPEC→ATT&CK chain leaves most top weaknesses, incl. XSS and SQLi, mapped to nothing). Drafted by Grok and spot-checked by Claude Opus 4.8.

Direction: other covers this; this covers other (F/M/P = full / mostly / partial).
