Volcano is a Kubernetes-native batch scheduling system
The Volcano webhook server is vulnerable to a denial-of-service attack due to the lack of a size limit on incoming HTTP request bodies. This can cause the server to run out of memory and become unresponsive. The vulnerability can be exploited by sending a large request body to the webhook endpoint.
Volcano is a Kubernetes-native batch scheduling system. Prior to v1.14.2, v1.13.3, and v1.12.4, the Volcano webhook server does not enforce a size limit on incoming HTTP request bodies. Any in-cluster pod that can reach the webhook endpoint may send an arbitrarily large request body, potentially causing the webhook server to be killed by OOM. All Volcano deployments with the webhook server exposed to in-cluster traffic are affected. This vulnerability is fixed in v1.14.2, v1.13.3, and v1.12.4.
Volcano deployments with the webhook server exposed to in-cluster traffic are at risk of a denial-of-service attack, with a medium level of severity.
