The version of application-gateway-kubernetes-ingress / cri-o / keda / kube-vip-cloud-provider / kured / moby-engine / node-problem-detector installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-21698 advisory.

  - client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package     in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version     1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential     memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an     instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`;
    not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our     middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`.
    client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including     removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected     promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method     given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow     a limited set of methods. (CVE-2022-21698)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
