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.

GO-2022-0230Improper limitation of path name in github.com/containernetworking/cni2022-07-01vendor · osvUS
The FindInPath function is vulnerable to directory traversal attacks, potentially permitting attackers to execute arbitrary binaries. This function does not sanitize its plugin parameter, so parameter names containing "../" or other such elements may reference arbitrary locations on the filesystem.
