CWE-274: Improper Handling of Insufficient Privileges

Weakness ID: 274
Vulnerability Mapping: DISCOURAGEDThis CWE ID should not be used to map to real-world vulnerabilities
Abstraction: BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.

For users who are interested in more notional aspects of a weakness. Example: educators, technical writers, and project/program managers. For users who are concerned with the practical application and details about the nature of a weakness and how to prevent it from happening. Example: tool developers, security researchers, pen-testers, incident response analysts. For users who are mapping an issue to CWE/CAPEC IDs, i.e., finding the most appropriate CWE for a specific issue (e.g., a CVE record). Example: tool developers, security researchers.

+ Description
The product does not handle or incorrectly handles when it has insufficient privileges to perform an operation, leading to resultant weaknesses.
+ Common Consequences
Section HelpThis table 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: Other; Alter Execution Logic

+ Relationships
Section HelpThis table 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.

+ Observed Examples
ReferenceDescription
System limits are not properly enforced after privileges are dropped.
Firewall crashes when it can't read a critical memory block that was protected by a malicious process.
Does not give admin sufficient privileges to overcome otherwise legitimate user actions.

Primary
(where the weakness exists independent of other weaknesses)
+ Detection Methods

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.)

Effectiveness: High

+ Memberships
Section HelpThis 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.

+ Vulnerability Mapping Notes

Usage: DISCOURAGED

(this CWE ID should not be used to map to real-world vulnerabilities)

Reasons: Potential Deprecation, CWE Overlap

Rationale:

This CWE entry could be deprecated in a future version of CWE.

Comments:

See maintenance notes.
+ Notes

Relationship

Overlaps dropped privileges, insufficient permissions.

Theoretical

This has a layering relationship with Unchecked Error Condition and Unchecked Return Value.

Theoretical

Within the context of vulnerability theory, privileges and permissions are two sides of the same coin. Privileges are associated with actors, and permissions are associated with resources. To perform access control, at some point the product makes a decision about whether the actor (and the privileges that have been assigned to that actor) is allowed to access the resource (based on the permissions that have been specified for that resource).

Maintenance

CWE-280 and CWE-274 are too similar. It is likely that CWE-274 will be deprecated in the future.
