CWE-351: Insufficient Type Distinction

Weakness ID: 351
Abstraction: Base
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The software does not properly distinguish between different types of elements in a way that leads to insecure behavior.
+ 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.

+ 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.

+ Observed Examples
ReferenceDescription
Browser user interface does not distinguish between user-initiated and synthetic events.
Product does not compare all required data in two separate elements, causing it to think they are the same, leading to loss of ACLs. Similar to Same Name error.
+ Memberships
This MemberOf Relationships table shows additional CWE Categories and Views that reference this weakness as a member. This information is often useful in understanding where a weakness fits within the context of external information sources.
