CVE-2023-5907: file manager vulnerability

What is known

The File Manager WordPress plugin before 6.3 does not restrict the file managers root directory, allowing an administrator to set a root outside of the WordPress root directory, giving access to system files and directories even in a multisite setup, where site administrators should not be allowed to modify the sites files.

Business impact

Successful exploitation of CVE-2023-5907, a medium vulnerability (CVSS 6.5) 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.
