CVE-2023-4239: real estate manager vulnerability

What is known

The Real Estate Manager plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 7.2 due to insufficient restriction on the 'rem_save_profile_front' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wp_capabilities' parameter during a profile update.

Business impact

Successful exploitation of CVE-2023-4239, a high vulnerability (CVSS 8.8) affecting real estate 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 real estate 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.
