cri-o: pod with access to 'hostIPC' and 'hostNetwork' kernel namespace allows sysctl from the list of safe sysctls to be applied to the host

An incorrect sysctls validation vulnerability was found in CRI-O. The sysctls from the list of "safe" sysctls specified for the cluster 0 will be applied to the host if an attacker can create a pod with a hostIPC and hostNetwork kernel namespace...

Privilege Escalation

github.com/cri-o/cri-o is vulnerable to Privilege Escalation. when the pod is using a host network or IPC namespace, which allows a malicious user to set sysctls on the host without having access to hostNetwork and hostIPC...

Sysctls applied to containers with host IPC or host network namespaces can affect the host

Impact Before setting the sysctls for a pod, the pods namespaces must be unshared created. However, in cases where the pod is using a host network or IPC namespace, a bug in CRI-O caused the namespace creating tool pinns to configure the sysctls of the host. This allows a malicious user to set...

Validation Bypass

github.com/cri-o/cri-o is vulnerable to Validation Bypass. When an attacker creates a pod with a hostIPC and hostNetwork kernel namespace, the attacker is able to apply sysctls from the list of safe sysctls specified for the cluster resulting in unauthorized access due to insufficient validations...

CVE-2022-0532

According to IBM’s security bulletin on CVE-2022-0532, Red Hat OpenShift on IBM Cloud is affected by a CRI-O vulnerability (CVE-2022-0532) caused by improper sysctls validation. A remote authenticated attacker could abuse hostIPC/hostNetwork to apply cluster-safe sysctls to the host, bypassing re...
