CVE-2022-31073: Cherry-pick GHSA-vwm6-qc77-v2rh: fix invalid request by kevin-wangzefeng · Pull Request #4042 · kubeedge/kubeedge
KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, 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 accidentally 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. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable the ServiceBus module in the config file edgecore.yaml.

### 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 disclosin...
