Détail du CWE-1293

The product relies on one source of data, preventing the ability to detect if an adversary has compromised a data source.

Modes d'introduction

Architecture and Design : This flaw could be introduced during the design of the application or misconfiguration at run time by only specifying a single point of validation.
Implementation : Such issues could be introduced during hardware implementation, then identified later during Testing or System Configuration phases.
Operation : This weakness could be introduced by intentionally failing all but one of the devices used to retrieve the data or by failing the devices that validate the data.

Conséquences courantes

Mesures d’atténuation potentielles

Phases : Requirements
Design system to use a Practical Byzantine fault method, to request information from multiple sources to verify the data and report on potentially compromised information sources.
Phases : Implementation
Failure to use a Practical Byzantine fault method when requesting data. Lack of place to report potentially compromised information sources. Relying on non-independent information sources for integrity checking. Failure to report information sources that respond in the minority to incident response procedures.

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.
