CPE, wat staat voor Common Platform Enumeration, is een gestandaardiseerd schema voor het benoemen van hardware, software en besturingssystemen. CPE biedt een gestructureerd naamgevingsschema om IT-systemen, platforms en pakketten uniek te identificeren en te classificeren op basis van bepaalde attributen zoals leverancier, productnaam, versie, update, editie en taal.

Naam: Missing Reference to Active Allocated Resource

The product does not properly maintain a reference to a resource that has been allocated, which prevents the resource from being reclaimed.

Detectiemethoden

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

Notities kwetsbaarheidsmapping

Rechtvaardiging : 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.
Opmerking : 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.

Notities

This weakness might not frequently apply to applications written in languages or frameworks that automatically perform garbage collection, since the removal of all references may act as a signal that the resource is ready to be reclaimed.
