CVE-2018-16874

Disclosure Date: December 14, 2018 •
CVE-2018-16874 CVSS v3 Base Score: 8.1
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

In Go before 1.10.6 and 1.11.x before 1.11.3, the “go get” command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly braces (both ‘{’ and ‘}’ characters). Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). The attacker can cause an arbitrary filesystem write, which can lead to code execution.
