#VU77528 Code Injection in Go programming language - CVE-2023-29402

Vulnerability identifier: #VU77528

Vulnerability risk: Medium

CVSSv4.0: 4.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-29402

CWE-ID: CWE-94

Exploitation vector: Network

Exploit availability: No

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

Vendor: Google

Description

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

The vulnerability exists due to improper input validation within the cgo go command when building code that contains directories with newline characters in their names. A remote attacker can pass specially crafted input to the cgo command at build time and potentially compromise the system.

Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected).

Mitigation
Install updates from vendor's website.

Vulnerable software versions

Go programming language: 1.0 - 1.0.3, 1.1 - 1.19.9, 1.2 - 1.20.4, 1.3 - 1.3.3, 1.4 - 1.4.3, 1.5 - 1.5.4, 1.6 - 1.6.4, 1.7 - 1.7.6, 1.8 - 1.8.7, 1.9 - 1.9.7
