CVE-2015-4018 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the FeedWordPress WordPress plugin, affecting versions < 2015.0514. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2015.0514; sites on affected versions should update now. Disclosed May 2015, reported by Adrián M. F..

Vulnerability Overview

SQL injection vulnerability in feedwordpresssyndicationpage.class.php in the FeedWordPress plugin before 2015.0514 for WordPress allows remote authenticated users to execute arbitrary SQL commands via the link_ids[] parameter in an Update action in the syndication.php page to wp-admin/admin.php.

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, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in FeedWordPress < 2015.0514 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For FeedWordPress the fix is 2015.0514: builds < 2015.0514 are affected, anything from 2015.0514 onward is not.

Remediation

Update to version 2015.0514, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to FeedWordPress: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: FeedWordPress 2015.0514 closes this, and updating the plugin is the step that ends it.
