CVE-2024-1476: under construction \/ maintenance mode vulnerability

What is known

The Under Construction / Maintenance Mode from Acurax plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.6 via the REST API. This makes it possible for unauthenticated attackers to obtain the contents of posts and pages when maintenance mode is active thus bypassing the protection provided by the plugin.

Business impact

Successful exploitation of CVE-2024-1476, a medium vulnerability (CVSS 5.3) affecting under construction \/ maintenance mode, 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 under construction \/ maintenance mode 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.
