Last modified

CVE-2019-3779 is a vulnerability of currently unknown severity. Cloud Foundry Container Runtime, versions prior to 0.29.0, deploys Kubernetes clusters utilize the same CA (Certificate Authority) to sign and trust certs for ETCD as used by the Kubernetes API. This could allow a user authenticated with a cluster to request a signed certificate leveraging the Kubernetes CSR capability to obtain a credential that could escalate privilege access to ETCD.. EPSS estimates a 0.68% chance of exploitation in the next 30 days.
