The issue is fixed in version 14.6.10; sites on affected versions should update now. Disclosed April 2015.

Vulnerability Overview

The cforms2 plugin before 14.6.10 for WordPress has SQL injection via several parameters.

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 cformsII < 14.6.10 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 cformsII the fix is 14.6.10: builds < 14.6.10 are affected, anything from 14.6.10 onward is not.

Remediation

Update to version 14.6.10, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to cformsII: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: cformsII 14.6.10 closes this, and updating the plugin is the step that ends it.
