CWE-556: ASP.NET Misconfiguration: Use of Identity Impersonation
Configuring an ASP.NET application to run with impersonated credentials may give the application unnecessary privileges.
How it's found
ASP.NET Misconfiguration: Use of Identity Impersonation is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
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.
Consequences
- Gain Privileges or Assume Identity
Mitigations
- Architecture and Design: Use the least privilege principle.
