Published Jan 9, 2025CWE-732EPSS 0.27%

Overview

CVE-2023-38037 is a medium-severity vulnerability. It was published on January 9, 2025 and has a CVSS 3.0 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.0 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

ActiveSupport::EncryptedFile writes contents that will be encrypted to a

temporary file. The temporary file's permissions are defaulted to the user's

current `umask` settings, meaning that it's possible for other users on the

same system to read the contents of the temporary file.

Attackers that have access to the file system could possibly read the contents

of this temporary file while a user is editing it.

All users running an affected release should either upgrade or use one of the

workarounds immediately.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
