CVE-2021-20206 (GCVE-0-2021-20206)

Vulnerability from cvelistv5 – Published: 2021-03-26 21:34 – Updated: 2024-08-03 17:30

Summary

An improper limitation of path name flaw was found in containernetworking/cni in versions before 0.8.1. When specifying the plugin to load in the 'type' field in the network configuration, it is possible to use special elements such as "../" separators to reference binaries elsewhere on the system. This flaw allows an attacker to execute other existing binaries other than the cni plugins/types, such as 'reboot'. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Severity

No CVSS data available.
