CVE-2024-7620: customizer export\/import vulnerability

What is known

The Customizer Export/Import plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the '_import' function in all versions up to, and including, 0.9.7. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: This vulnerability is only exploitable when used in conjunction with a race condition as the uploaded file is deleted shortly after it is created.

Business impact

Successful exploitation of CVE-2024-7620, a medium vulnerability (CVSS 6.6) affecting customizer export\/import, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether customizer export\/import is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
