Vulnerability Overview

The Ivory Search – WordPress Search Plugin plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 5.5.6 via the ajax_load_posts function. This makes it possible for unauthenticated attackers to extract text data from password-protected posts using the boolean-based attack on the AJAX search form

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Ivory Search <= 5.5.6 takes a caller who can reach the endpoint. 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 Ivory Search the fix is 5.5.7: builds <= 5.5.6 are affected, anything from 5.5.7 onward is not.

Remediation

Update to version 5.5.7, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Ivory Search 5.5.7 closes this, and updating the plugin is the step that ends it.
