CVE-2024-9235: mapster wp maps vulnerability

What is known

The Mapster WP Maps plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to an insufficient capability check on the mapster_wp_maps_set_option_from_js() function in all versions up to, and including, 1.5.0. This makes it possible for authenticated attackers, with contributor-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.

Business impact

Successful exploitation of CVE-2024-9235, a high vulnerability (CVSS 8.8) affecting mapster wp maps, 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 mapster wp maps 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.
