Uncontrolled Resource Consumption


Severity Medium
Score 6.5/10


KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Versions prior to 1.9.4, 1.10.0 prior to 1.10.2, and 1.11.0 prior to 1.11.1, a large response received by the viaduct WSClient can cause a DoS from memory exhaustion. The entire body of the response is being read into memory which could allow an attacker to send a request that returns a response with a large body. The consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. The software is affected If users who are authenticated to the edge side connect to `cloudhub` from the edge side through WebSocket protocol. This bug has been fixed in Kubeedge 1.9.4, 1.10.2, and 1.11.1. There are currently no known workarounds.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
