What is known
The 3DPrint Lite WordPress plugin before 1.9.1.5 does not have any authorisation and does not check the uploaded file in its p3dlite_handle_upload AJAX action , allowing unauthenticated users to upload arbitrary file to the web server. However, there is a .htaccess, preventing the file to be accessed on Web servers such as Apache.
Business impact
Successful exploitation of CVE-2021-4436, a critical vulnerability (CVSS 9.8) affecting 3dprint lite, 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 3dprint lite 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.
