EUVDB-ID: #VU11851

Risk: High

CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-7187

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The weakness exists in the "go get" implementation due to insufficient validation of the import path (get/vcs.go only checks for "://" anywhere in the string) when the -insecure command-line option is used. A remote attacker can trick the victim into visiting a specially crafted website, inject OS commands and execute arbitrary code.

Mitigation

Update the affected packages.
