CVE-2020-15187 Detail

Current Description

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. 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.

CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  4.7 MEDIUM
Vector:  CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  3.0 LOW
Vector:  CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:N


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
