Description

Impact

What kind of vulnerability is it? Who is impacted? The NMI component in AAD Pod Identity intercepts and validates token requests based on regex. In this case, a token request made with backslash in the request (example: /metadata/identity\oauth2\token/) would bypass the NMI validation and be sent to IMDS allowing a pod in the cluster to access identities that it shouldn't have access to.

Patches

Has the problem been patched? What versions should users upgrade to?

  • We analyzed this bug and determined that we needed to fix it. This fix has been included in AAD Pod Identity release v1.8.13
  • If using the AKS pod-managed identities add-on, no action is required. The clusters should now be running the v1.8.13 release.
