Description Preview

The InfiniteWP Client plugin for WordPress contains a vulnerability in the 'admin_notice' function that exposes sensitive information. This vulnerability affects versions up to and including 1.11.1. Authenticated attackers with subscriber-level permissions or higher can exploit this vulnerability to extract sensitive configuration data. The vulnerability is only exploitable if the plugin has not been configured yet. If combined with another vulnerability that allows arbitrary plugin installation and activation, an attacker could potentially connect a site to InfiniteWP, enabling remote management and privilege escalation.

Overview

CVE-2023-2916 is a CWE-668 (Exposure of Resource to Wrong Sphere) vulnerability in the InfiniteWP Client WordPress plugin. The vulnerability exists in the 'admin_notice' function which improperly protects sensitive configuration data. When exploited, an attacker with minimal authentication privileges (subscriber or higher) can access sensitive information that should be restricted to administrators. This vulnerability is particularly concerning because it could be chained with other vulnerabilities to gain remote management capabilities and escalate privileges on the affected WordPress site. The vulnerability only affects sites where the InfiniteWP Client plugin is installed but not yet configured.

Remediation

To remediate this vulnerability, site administrators should:

  1. Update the InfiniteWP Client plugin to a version newer than 1.11.1
  2. Ensure that the plugin is properly configured if it must be used
  3. Review user roles and permissions to limit the number of authenticated users who could potentially exploit this vulnerability
  4. Monitor for suspicious activities that might indicate attempts to exploit this vulnerability
  5. Consider implementing additional security layers such as Web Application Firewalls (WAF) that can help detect and block exploitation attempts
