Veelvoorkomende gevolgen

Bereik	Impact	Waarschijnlijkheid
Integrity	Modify Memory Opmerking: The function or method that has been called can alter or delete the mutable data. This could violate assumptions that the calling function has made about its state. In situations where unknown code is called with references to mutable data, this external code could make changes to the data sent. If this data was not previously cloned, the modified data might not be valid in the context of execution.

Mogelijke risicobeperkingen

Phases : Implementation
Pass in data which should not be altered as constant or immutable.
Phases : Implementation
Clone all mutable data before passing it into an external function . This is the preferred mitigation. This way, regardless of what changes are made to the data, a valid copy is retained for use by the class.

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.
