| Likelihood of exploit | — |
Description
The product uses multiple resources that can have the same identifier, in a context in which unique identifiers are required.
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.
Common consequences
- Access Control: Bypass Protection Mechanism
- Other: Quality Degradation
Mitigations
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.
