Description
containerd is an open-source container runtime. Versions 0.1.0 through 1.7.28, 2.0.0-beta.0 through 2.0.6, 2.1.0-beta.0 through 2.1.4 and 2.2.0-beta.0 through 2.2.0-rc.1 have an overly broad default permission vulnerability. Directory paths `/var/lib/containerd`, `/run/containerd/io.containerd.grpc.v1.cri` and `/run/containerd/io.containerd.sandbox.controller.v1.shim` were all created with incorrect permissions. This issue is fixed in versions 1.7.29, 2.0.7, 2.1.5 and 2.2.0. Workarounds include updating system administrator permissions so the host can manually chmod the directories to not have group or world accessible permissions, or to run containerd in rootless mode.

Executive Summary

This vulnerability in containerd involves overly broad default permissions on certain directory paths such as /var/lib/containerd and others. These directories were created with incorrect permissions that allow more access than intended, potentially exposing sensitive data or allowing unauthorized actions. The issue affects multiple versions of containerd and is fixed in later versions.

Impact Analysis

The overly broad permissions can lead to unauthorized access or modification of container runtime data, which may compromise confidentiality, integrity, and availability of container workloads. This could allow attackers with limited privileges to escalate their access or disrupt container operations.

Detection Guidance

You can detect this vulnerability by checking the permissions of the directories `/var/lib/containerd`, `/run/containerd/io.containerd.grpc.v1.cri`, and `/run/containerd/io.containerd.sandbox.controller.v1.shim`. Use commands like `ls -ld /var/lib/containerd /run/containerd/io.containerd.grpc.v1.cri /run/containerd/io.containerd.sandbox.controller.v1.shim` to inspect their permissions. If these directories have group or world accessible permissions, the system may be vulnerable.

Mitigation Strategies

Immediate mitigation steps include updating the permissions of the affected directories to remove group and world access using commands such as `chmod go-rwx /var/lib/containerd /run/containerd/io.containerd.grpc.v1.cri /run/containerd/io.containerd.sandbox.controller.v1.shim`. Alternatively, running containerd in rootless mode can also mitigate the issue. Ultimately, updating containerd to fixed versions 1.7.29, 2.0.7, 2.1.5, or 2.2.0 is recommended.
