CWE-556: ASP.NET Misconfiguration: Use of Identity Impersonation

Weakness ID: 556
Abstraction: Variant
Structure: Simple
Status: Incomplete
Presentation Filter:
+ Description
Configuring an ASP.NET application to run with impersonated credentials may give the application unnecessary privileges.
+ Extended Description
The use of impersonated credentials allows an ASP.NET application to run with either the privileges of the client on whose behalf it is executing or with arbitrary privileges granted in its configuration.
+ 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)
NatureTypeIDName
ChildOfBaseBase - a weakness that is described in an abstract fashion, but with sufficient details to infer specific methods for detection and prevention. More general than a Variant weakness, but more specific than a Class weakness.266Incorrect Privilege Assignment

+ 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.
