Détail du CWE-1292

The product implements a conversion mechanism to map certain bus-transaction signals to security identifiers. However, if the conversion is incorrectly implemented, untrusted agents can gain unauthorized access to the asset.

Modes d'introduction

Architecture and Design : Such issues could be introduced during hardware architecture and design, then identified later during Testing or System Configuration phases.
Implementation : Such issues could be introduced during hardware implementation, then identified later during Testing or System Configuration phases.

Notes de cartographie des vulnérabilités

Justification : This CWE entry is at the Base 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.
