Summary

CVE-2024-25679 is a medium-severity Use of a Key Past its Expiration Date (CWE-324) vulnerability in Pquic Pquic. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

Vulnerability Data

In PQUIC before 5bde5bb, retention of unused initial encryption keys allows attackers to disrupt a connection with a PSK configuration by sending a CONNECTION_CLOSE frame that is encrypted via the initial key computed. Network traffic sniffing is needed as part…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-12 Cryptographic Key Establishment and Management good match

SC-12 requires establishing and managing cryptographic keys including distribution, storage, access and destruction, which directly enforces expiration and rotation policies.

IA-5 Authenticator Management good match

IA-5 requires managing authenticators (including passwords and tokens) with verification, distribution and revocation steps that cover expiration enforcement.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

ID.AM-08 partial match
prevents

Lifecycle management of cryptographic assets directly includes enforcing key expiration and rotation.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography mostly match
prevents

Use-of-cryptography control explicitly covers key lifecycle management including expiration and rotation.

A.5.17 Authentication information partial match
prevents

Authentication information policy should mandate key rotation and expiry, directly preventing use of expired keys.

A.8.32 Change management partial match
mitigates

Change-management processes can trigger key rotation, but do not inherently enforce cryptographic expiry rules.

A.8.5 Secure authentication partial match
degrades

Secure authentication requires cryptographic keys to be replaced before expiry, mitigating the weakness.
