CVE-2020-11498 (opens in a new tab)How to fix?
Upgrade github.com/slackhq/nebula to version 1.2.0 or higher.
Overview
github.com/slackhq/nebula is a scalable overlay networking tool with a focus on performance, simplicity and security.
Affected versions of this package are vulnerable to Path Traversal. Slack Nebula through 1.1.0 contains a relative path vulnerability that allows a low-privileged attacker to execute code in the context of the root user via tun_darwin.go or tun_windows.go. A user can also use Nebula to execute arbitrary code in the user's own context, e.g., for user-level persistence or to bypass security controls. NOTE: the vendor states that this "requires a high degree of access and other preconditions that are tough to achieve."
