Nom: Use of Multiple Resources with Duplicate Identifier

The product uses multiple resources that can have the same identifier, in a context in which unique identifiers are required.

Description du CWE

If the product assumes that each resource has a unique identifier, the product could operate on the wrong resource if attackers can cause multiple resources to be associated with the same identifier.

Note: If unique identifiers are assumed when protecting sensitive resources, then duplicate identifiers might allow attackers to bypass the protection.

Références Description

CVE-2013-4787

chain: mobile OS verifies cryptographic signature of file in an archive, but then installs a different file with the same name that is also listed in the archive.

Mesures d’atténuation potentielles

Phases : Architecture and Design
Where possible, use unique identifiers. If non-unique identifiers are detected, then do not operate any resource with a non-unique identifier and report the error appropriately.

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.

NotesNotes

This weakness is probably closely associated with other issues related to doubling, such as CWE-675 (Duplicate Operations on Resource). It's often a case of an API contract violation (CWE-227).
