Vulnerability from github – Published: 2022-07-11 21:01 – Updated: 2022-07-19 22:29
VLAI
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.
