Nom: Improper Validation of Certificate Expiration

A certificate expiration is not validated or is incorrectly validated.

Informations générales

Modes d'introduction

Implementation : When the software uses certificate pinning, the developer might not properly validate all relevant components of the certificate before pinning the certificate. This can make it difficult or expensive to test after the pinning is complete.
Implementation : REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Conséquences courantes

Portée Impact Probabilité
Integrity
Other		Other

Note: The data read from the system vouched for by the expired certificate may be flawed due to malicious spoofing.
Authentication
Other		Other

Note: Trust may be assigned to certificates that have been abandoned due to age.

Mesures d’atténuation potentielles

Phases : Architecture and Design
Check for expired certificates and provide the user with adequate information about the nature of the problem and how to proceed.
Phases : Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the expiration.

Notes de cartographie des vulnérabilités

Justification : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Commentaire : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
