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). This issue has been patched in Helm 2.16.11 and Helm 3.3.2. As a possible workaround make sure to install plugins using a secure connection protocol like SSL.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2020-09-17 22:15:00","updated_at":"2021-11-18 17:51:00"},"problem_types":["NVD-CWE-Other"],"metrics":[],"references":[{"url":"https://github.com/helm/helm/security/advisories/GHSA-c52f-pq47-2r9j","name":"https://github.com/helm/helm/security/advisories/GHSA-c52f-pq47-2r9j","refsource":"CONFIRM","tags":["Third Party Advisory"],"title":"plugin.yaml file allows for duplicate entries · Advisory · helm/helm · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b","name":"https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b","refsource":"MISC","tags":["Patch","Third Party Advisory"],"title":"Merge pull request from GHSA-c52f-pq47-2r9j · helm/helm@d9ef5ce · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2020-15187","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15187","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2020","cve_id":"15187","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"helm","cpe5":"helm","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2020","cve_id":"15187","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"helm","cpe5":"helm","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2020-15187","qid":"980048","title":"Go (go) Security Update for helm.sh/helm/v3/pkg/plugin (GHSA-c52f-pq47-2r9j)"}]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2020-15187","STATE":"PUBLIC","TITLE":"Duplicate plugin entries in Helm"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"helm","version":{"version_data":[{"version_value":">= 2.0.0, < 2.16.11"},{"version_value":">= 3.0.0, < 3.3.2"}]}}]},"vendor_name":"helm"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"In Helm before versions 2.16.11 and 3.3.2, a Helm plugin can contain duplicates of the same entry, with the last one always used.
