Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Code Injection

EUVDB-ID: #VU77528

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-29402

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

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.

http://go.dev/cl/501226


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU77529

Risk: Medium

CVSSv3.1: 7.8 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-29403

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists within Go runtime due to application allows to execute setuid/setgid binaries without any restrictions. An attacker with ability to control the application flow can execute arbitrary code on the system with elevated privileges.

Mitigation

Install updates from vendor's website.

3) Code Injection

EUVDB-ID: #VU77530

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-29404

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists within Go runtime when running "go get" on a malicious module, or when running any other
command which builds untrusted code.A remote attacker can inject and execute arbitrary code on the target system at build time when using cgo.

Mitigation

Install updates from vendor's website.
