IBM Cloud Private for Data is affected multiple security vulnerabilities in IBM
Cloud Private Kubernetes
Product: IBM Cloud Private for Data
Software version: All Versions
Operating system(s): Linux
Software edition: 1.2.0, 1.2.1, 2.1.0
Reference #: 0886609
Security Bulletin
Summary
IBM Cloud Private for Data is affected by multiple security vulnerabilites in
Kubernetes which in some cases can allow unauthorized access to the Kubernetes
API Server and/or trusted user privilege escalation.
Vulnerability Details
CVEID: CVE-2019-9946
DESCRIPTION: Kubernetes could provide weaker than expected security, caused by
an interaction when paired with the embedded CNI (Container Networking
Interface) that uses the portmap plugin. The portmap plugin inserts rules at
the front of the iptables nat chains which would take precedence over the KUBE-
SERVICES chain. The HostPort/portmap rule allows for matching of incoming
traffic even if there are better fitting.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
158803 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2019-1002101
DESCRIPTION: Kubernetes could allow a remote attacker to traverse directories
on the system, caused by the improper handling of symlinks. By persuading a
victim to use the kubectl cp command or the oc cp command with a malicious
container, an attacker could replace or delete arbitrary files on the host
machine.
