CVE-2020-2023:
vulnerability analysis and mitigation
Overview
Kata Containers prior to versions 1.11.1, 1.10.5, and 1.9 contained a vulnerability where containers were not restricted from accessing the guest's root filesystem device. This vulnerability was assigned CVE-2020-2023 and was discovered in late 2019 (CVE Details).
Technical details
The vulnerability allowed malicious containers to gain unauthorized access to the guest's root filesystem device. This security flaw existed because Kata Containers didn't properly implement restrictions on container access to the guest's root filesystem device (CVE Details).
Impact
If exploited, malicious containers could gain code execution capabilities on the guest system and masquerade as the kata-agent, potentially compromising the security of the container environment (CVE Details).
Exploitability
The vulnerability affected Kata Containers versions 1.11 earlier than 1.11.1, 1.10 versions earlier than 1.10.5, and version 1.9 and earlier releases (CVE Details).
Mitigation and workarounds
The vulnerability was addressed in Kata Containers versions 1.11.1 and 1.10.5. The fix involved explicitly denying container access to the nvdimm root partition by adding the nvdimm device to the device cgroup (Runtime Release, Runtime Release).
