At a glance

CVE-2015-9454 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Smooth Slider WordPress plugin, affecting versions <= 2.6.5. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 2.7; sites on affected versions should update now. Disclosed July 2015, reported by Marcin Probola.

Vulnerability Overview

The Smooth Slider plugin before 2.7 for WordPress has SQL Injection via the wp-admin/admin.php?page=smooth-slider-admin current_slider_id parameter.

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 Smooth Slider <= 2.6.5 takes any authenticated account. 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 Smooth Slider the fix is 2.7: builds <= 2.6.5 are affected, anything from 2.7 onward is not.

Remediation

Update to version 2.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Smooth Slider: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Smooth Slider 2.7 closes this, and updating the plugin is the step that ends it.
