Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-29187

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

Exploit availability: No

Description

The vulnerability allows a remote user to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions. A remote user can bypass implemented security restrictions and privilege escalation on the system when navigating as root into a shared tmp directory owned by the victim, but where an attacker can create a git repository.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Apple Xcode: 13.0 - 14.0.1

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Input validation error

EUVDB-ID: #VU68517

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-39253

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: Yes

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 update from vendor's website.
