CVE-2023-2916
At a glance
CVE-2023-2916 is a high-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the InfiniteWP Client WordPress plugin, affecting versions <= 1.11.1. It carries a CVSS score of 7.5 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.12.1; sites on affected versions should update now. Disclosed August 2023, reported by István Márton.
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
InfiniteWP Client <= 1.11.1 carries this weakness at admin_notice, and reaching it takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For InfiniteWP Client the fix is 1.12.1: builds <= 1.11.1 are affected, anything from 1.12.1 onward is not.
Remediation
Update to version 1.12.1, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: InfiniteWP Client 1.12.1 closes this, and updating the plugin is the step that ends it.
