KubeEdge CloudCore Router memory exhaustion

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 CloudCore Router does not impose a limit on the size of responses to requests made by the REST handler. An attacker could use this weakness to make a request that will return an HTTP response with a large body and cause DoS of CloudCore. In the HTTP Handler API, the rest handler makes a request to a pre-specified handle. The handle will return an HTTP response that is then read into memory. The consequence of the exhaustion is that CloudCore will be in a denial of service. Only an authenticated user of the cloud can make an attack. It will be affected only when users enable `router` module in the config file `cloudcore.yaml`. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable the router switch in the config file `cloudcore.yaml`.

KubeEdge 资源管理错误漏洞

KubeEdge是KubeEdge开源的一个 Kubernetes 原生边缘计算框架。基于 Kubernetes 构建，并将本机容器化应用编排和设备管理扩展到边缘主机。 KubeEdge 1.11.1之前版本、1.10.2之前版本 和 1.9.4之前版本存在资源管理错误漏洞，该漏洞源于CloudCore 路由器不对 REST 处理程序发出的请求的响应大小施加限制，攻击者利用该漏洞可以发送大消息来耗尽内存并导致 DoS。
