KubeEdge Edge ServiceBus module DoS
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
.
