Detailsinfo

A vulnerability classified as problematic has been found in Helm up to 2.16.10/3.3.1. Affected is an unknown part of the component Chart Handler. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In Helm before versions 2.16.11 and 3.3.2, a Helm repository can contain duplicates of the same chart, with the last one always used. If a repository is compromised, this lowers the level of access that an attacker needs to inject a bad chart into a repository. To perform this attack, an attacker must have write access to the index file (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to manually review the index file in the Helm repository cache before installing software.

The weakness was shared 09/17/2020 (GitHub Repository). The advisory is available at github.com. This vulnerability is traded as CVE-2020-15185 since 06/25/2020. The exploitability is told to be difficult. It is possible to launch the attack remotely. Additional levels of successful authentication are needed for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1055 by the MITRE ATT&CK project.

Upgrading to version 2.16.11 or 3.3.2 eliminates this vulnerability.
