Vulnerability identifier: #VU12162

Vulnerability risk: Low

CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-6574

CWE-ID: CWE-77

Exploitation vector: Network

Exploit availability: Yes

Vulnerable software:
Go programming language
Universal components / Libraries / Scripting languages

Vendor: Google

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

The weakness exists due to "go get" remote command execution during source code build, by leveraging the gcc or clang plugin feature, because -fplugin= and -plugin= arguments were not blocked. A remote attacker can execute arbitrary commands.

Mitigation
Update to versions 1.8.7, 1.9.4 or 1.10rc2.

Vulnerable software versions

Go programming language: 1.8 - 1.8.6, 1.9 - 1.9.3, 1.10 rc1
