3) UNIX Hard Link

EUVDB-ID: #VU91286

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-32020

CWE-ID: CWE-62 - UNIX Hard Link

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the original repository.

The vulnerability exists due to insecure hardlink following when working with local clones. Local clones may end up hardlinking files into the target repository's object database when source and target repository reside on the same disk. If the source repository is owned by a different user, then those hardlinked files may be rewritten at any point in time by the untrusted user.

Mitigation

Install updates from vendor's repository.

4) UNIX symbolic link following

EUVDB-ID: #VU91287

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-2024-32021

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the original repository.

The vulnerability exists due to insecure symlink following issue. When cloning a local source repository that contains symlinks via the filesystem, Git may create hardlinks to arbitrary user-readable files on the same filesystem as the target repository in the objects/ directory.

Mitigation

Install updates from vendor's repository.

6) Input validation error

EUVDB-ID: #VU68517

Risk: Low

CVSSv3.1: 2.8 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-39253

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to the way Git handles hardlinks when performing a local clone. A remote attacker can trick the victim into clocking a malicious repository and create or copy hardlinks to critical files on the system, which can result in sensitive information exposure.

Mitigation

Install updates from vendor's repository.
