GHSA-9FJ4-3849-RV9G OpenKruise PodProbeMarker is Vulnerable to SSRF via Unrestricted Host Field

Summary PodProbeMarker allows defining custom probes with TCPSocket or HTTPGet handlers. The webhook validation does not restrict the Host field in these probe configurations. Since kruise-daemon runs with hostNetwork=true, it executes probes from the node network namespace. An attacker with...

Incorrect Permission Assignment for Critical Resource in CRI-O

An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace...

Kubernetes: Man in the middle leading to root privilege escalation using hostNetwork=true (CAP_NET_RAW considered harmful)

Summary: CAPNETRAW capability is still included by default in K8S, leading to yet another attack. An attacker gaining access to a hostNetwork=true container with CAPNETRAW capability can listen to all the traffic going through the host and inject arbitrary traffic, allowing to tamper with most...

CVE-2019-10200

A flaw was discovered in OpenShift Container Platform 4 where, by default, users with access to create pods also have the ability to schedule workloads on master nodes. Pods with permission to access the host network, running on master nodes, can retrieve security credentials for the master AWS I...
