CVE-2018-25105: file manager vulnerability

What is known

The File Manager plugin for WordPress is vulnerable to authorization bypass due to a missing capability check in the /inc/root.php file in versions up to, and including, 3.0. This makes it possible for unauthenticated attackers to download arbitrary files from the server and upload arbitrary files that can be used for remote code execution.

Business impact

Successful exploitation of CVE-2018-25105, a critical vulnerability (CVSS 9.8) affecting file manager, 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 file manager 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.
