CVE-2023-2916: infinitewp client vulnerability

What is known

The InfiniteWP Client plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.11.1 via the 'admin_notice' function. This can allow authenticated attackers with subscriber-level permissions or above to extract sensitive data including configuration. It can only be exploited if the plugin has not been configured yet. If combined with another arbitrary plugin installation and activation vulnerability, it may be possible to connect a site to InfiniteWP which would make remote management possible and allow for elevation of privileges.

Business impact

Successful exploitation of CVE-2023-2916, a high vulnerability (CVSS 7.5) affecting infinitewp client, 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 infinitewp client 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.
