How to Fix CVE-2020-8567

To remediate this vulnerability, upgrade all affected Github.com/hashicorp/vault csi provider dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/hashicorp/vault-csi-provider fixed: 0.0.6 
Upgrade github.com/hashicorp/vault-csi-provider to 0.0.6
github.com/Azure/secrets-store-csi-driver-provider-azure fixed: 0.0.10 
Upgrade github.com/Azure/secrets-store-csi-driver-provider-azure to 0.0.10
github.com/GoogleCloudPlatform/secrets-store-csi-driver-provider-gcp fixed: 0.2.0 
Upgrade github.com/GoogleCloudPlatform/secrets-store-csi-driver-provider-gcp to 0.2.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/hashicorp/vault-csi-provider

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-8567, inspect your project dependencies for Github.com/hashicorp/vault csi provider:

inspect dependencies for github.com/hashicorp/vault-csi-provider

Analyze the terminal output to locate any version of Github.com/hashicorp/vault csi provider in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Github.com/hashicorp/vault csi provider, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Kubernetes Secrets Store CSI Driver Vault Plugin prior to v0.0.6, Azure Plugin prior to v0.0.10, and GCP Plugin prior to v0.2.0 allow an attacker who can create specially-crafted SecretProviderClass objects to write to arbitrary file paths on the host filesystem, including `/var/lib/kubelet/pods`.
