At a glance

CVE-2015-2090 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WordPress Survey & Poll WordPress plugin, affecting versions < 1.2. 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 1.2; sites on affected versions should update now. Disclosed May 2015, reported by Securely.

Vulnerability Overview

SQL injection vulnerability in the ajax_survey function in settings.php in the WordPress Survey and Poll plugin 1.1.7 for Wordpress allows remote attackers to execute arbitrary SQL commands via the survey_id parameter in an ajax_survey action to wp-admin/admin-ajax.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 WordPress Survey & Poll < 1.2 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 WordPress Survey & Poll the fix is 1.2: builds < 1.2 are affected, anything from 1.2 onward is not.

Remediation

Update to version 1.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WordPress Survey & Poll: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WordPress Survey & Poll 1.2 closes this, and updating the plugin is the step that ends it.
