CVE-2024-13333: advanced file manager vulnerability

What is known

The Advanced File Manager plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'fma_local_file_system' function in versions 5.2.12 to 5.2.13. This makes it possible for authenticated attackers, with Subscriber-level access and above and upload permissions granted by an administrator, to upload arbitrary files on the affected site's server which may make remote code execution possible. The function can be exploited only if the "Display .htaccess?" setting is enabled.

Business impact

Successful exploitation of CVE-2024-13333, a high vulnerability (CVSS 7.5) affecting advanced 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 advanced 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.
