Affected packages
• Go github.com/Azure/aad-pod-identity: < 1.8.13 → fixed in 1.8.13
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.
