CWE-281: Improper Preservation of Permissions

Weakness ID: 281
Abstraction: Base
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The software does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.

+ Relevant to the view "Research Concepts" (CWE-1000)

Class: Language-Independent (Undetermined Prevalence)

+ Common Consequences

The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

Technical Impact: Read Application Data; Modify Application Data

+ Observed Examples
ReferenceDescription
Incorrect ACLs used when restoring backups from directories that use symbolic links.
Automatic modification of permissions inherited from another file system.
Permissions on backup file are created with defaults, possibly less secure than original file.
File is made world-readable when being cloned.
