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.
