At a glance

CVE-2015-7791 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Welcart e-Commerce WordPress plugin, affecting versions < 1.5.3. 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 1.5.3; sites on affected versions should update now. Disclosed December 2015, reported by Shoji Baba.

Vulnerability Overview

Multiple SQL injection vulnerabilities in admin.php in the Collne Welcart plugin before 1.5.3 for WordPress allow remote authenticated users to execute arbitrary SQL commands via the (1) search[column] or (2) switch 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 Welcart e-Commerce < 1.5.3 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 Welcart e-Commerce the fix is 1.5.3: builds < 1.5.3 are affected, anything from 1.5.3 onward is not.

Remediation

Update to version 1.5.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Welcart e-Commerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Welcart e-Commerce 1.5.3 closes this, and updating the plugin is the step that ends it.
