How to Fix CVE-2020-15187

To remediate this vulnerability, upgrade all affected Helm.sh/helm/v3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

helm.sh/helm/v3 fixed: 3.3.2 
Upgrade helm.sh/helm/v3 to 3.3.2
helm.sh/helm fixed: 2.16.11 
Upgrade helm.sh/helm to 2.16.11
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 helm.sh/helm/v3

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-15187, inspect your project dependencies for Helm.sh/helm/v3:

inspect dependencies for helm.sh/helm/v3

Analyze the terminal output to locate any version of Helm.sh/helm/v3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.2), 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-694: Use of Multiple Resources with Duplicate Identifier, where the product uses multiple resources that can have the same identifier, in a context in which unique identifiers are required. In Helm.sh/helm/v3, 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

### Impact During a security audit of Helm's code base, Helm maintainers identified a bug in which a Helm plugin can contain duplicates of the same entry, with the last one always used. If a plugin is compromised, this lowers the level of access that an attacker needs to modify a plugin's install hooks, causing a local execution attack. To perform this attack, an attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded (which can occur during a MITM attack on a non-SSL connection). ### Patches This issue has been patched in Helm 2.16.11 and Helm 3.3.2. ### Workarounds Make sure to install plugins using a secure connection protocol like SSL.
