At a glance

This record tracks a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the EWWW Image Optimizer WordPress plugin, affecting versions < 7.2.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 7.2.1; sites on affected versions should update now. Disclosed September 2023.

Vulnerability Overview

The EWWW Image Optimizer for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 7.2.0 due to the plugin saving debug logs in predictable locations. This can allow unauthenticated attackers to obtain information about installation paths, file permissions and various plugin settings.

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 EWWW Image Optimizer < 7.2.1 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 EWWW Image Optimizer the fix is 7.2.1: builds < 7.2.1 are affected, anything from 7.2.1 onward is not.

Remediation

Update to version 7.2.1, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: EWWW Image Optimizer 7.2.1 closes this, and updating the plugin is the step that ends it.
