CVE-2023-6583: import and export users and customers vulnerability

What is known

The Import and export users and customers plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.24.2 via the Recurring Import functionality. This makes it possible for authenticated attackers, with administrator access and above, to read and delete the contents of arbitrary files on the server including wp-config.php, which can contain sensitive information.

Business impact

Successful exploitation of CVE-2023-6583, a medium vulnerability (CVSS 6.6) affecting import and export users and customers, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Confirm whether import and export users and customers 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.
