Summary: KubeEdge Cloud AdmissionController component DoS

Details: ### Impact Several endpoints including `/devicemodels`, `/rules`, `/ruleendpoints`, `/offlinemigration` in the Cloud Admissioncontroller may be susceptible to a DoS attack if an HTTP request containing a very large Body is sent to it. Only an authenticated user can cause this issue. It will be affected when users deploy a Cloud Admissioncontroller. The consequence of the exhaustion is that the Cloud Admissioncontroller will be in denial of service. ### Patches This bug has been fixed in Kubeedge 1.11.1, 1.10.2, 1.9.4. Users should update to these versions to resolve the issue. ### Workarounds At the time of writing, no workaround exists. ### References NA ### Credits Thanks David Korczynski and Adam Korczynski of ADA Logics for responsibly disclosing this issue in accordance with the [kubeedge security policy](https://github.com/kubeedge/kubeedge/security/policy) during a security audit sponsored by CNCF and facilitated by OSTIF. ### For more information If you have any questions or comments about this advisory: * Open an issue in [KubeEdge repo](https://github.com/kubeedge/kubeedge/issues/new/choose) * To make a vulnerability report, email your vulnerability to the private [[email protected]](mailto:[email protected]) list with the security details and the details expected for [KubeEdge bug reports](https://github.com/kubeedge/kubeedge/blob/master/.github/ISSUE_TEMPLATE/bug-report.md).
