Vulnerability Overview

The Ultimate CSV Importer plugin for WordPress is vulnerable to Sensitive Data Exposure in versions up to, and including, 3.6.74 via the modules/export/templates/export.php file. This can allow unauthenticated attackers to extract sensitive data including emails, passwords and usernames.

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. A successful exploit has high impact on confidentiality.

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

Reaching this weakness in WP Ultimate CSV Importer < 3.6.75 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 WP Ultimate CSV Importer the fix is 3.6.75: builds < 3.6.75 are affected, anything from 3.6.75 onward is not.

Remediation

Update to version 3.6.75, or a newer patched version

How does WordSec protect against this?
