Summary: KubeEdge Edge ServiceBus module DoS

Details: ### Impact The ServiceBus server on the edge side may be susceptible to a DoS attack if an HTTP request containing a very large Body is sent to it. It is possible for the node to be exhausted of memory. The consequence of the exhaustion is that other services on the node, e.g. other containers, will be unable to allocate memory and thus causing a denial of service. Malicious Apps which by accident pulled by users on the host and have the access to send HTTP requests to localhost may make an attack. It will be affected only when users enable the `ServiceBus` module in the config file `edgecore.yaml` as below: ``` modules: ... serviceBus: enable: true ``` ### 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 Disable the ServiceBus module in the config file `edgecore.yaml`. ### 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).
