At a glance

CVE-2015-4066 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the GigPress WordPress plugin, affecting versions < 2.3.9. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.3.9; sites on affected versions should update now. Disclosed May 2015, reported by Adrián M. F..

Vulnerability Overview

Multiple SQL injection vulnerabilities in admin/handlers.php in the GigPress plugin before 2.3.9 for WordPress allow remote authenticated users to execute arbitrary SQL commands via the (1) show_artist_id or (2) show_venue_id parameter in an add action in the gigpress.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 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 GigPress < 2.3.9 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 GigPress the fix is 2.3.9: builds < 2.3.9 are affected, anything from 2.3.9 onward is not.

Remediation

Update to version 2.3.9, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to GigPress: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: GigPress 2.3.9 closes this, and updating the plugin is the step that ends it.
