A vulnerability was found in KubeEdge up to 1.9.3/1.10.1/1.11.0. It has been declared as problematic. This vulnerability affects an unknown function of the component Cloud AdmissionController. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. As an impact it is known to affect availability. CVE summarizes:
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, several endpoints in the Cloud AdmissionController may be susceptible to a DoS attack if an HTTP request containing a very large Body is sent to it. The consequence of the exhaustion is that the Cloud AdmissionController will be in denial of service. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. There is currently no known workaround.
The weakness was published 07/12/2022 as GHSA-w52j-3457-q9wr. The advisory is shared for download at github.com. This vulnerability was named CVE-2022-31074 since 05/18/2022. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.
Upgrading to version 1.9.4, 1.10.2 or 1.11.1 eliminates this vulnerability.
