At a glance

This record tracks a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the RepairBuddy WordPress plugin, affecting versions <= 3.72. 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 3.73; sites on affected versions should update now. Disclosed May 2022.

Vulnerability Overview

The plugin CRM WordPress Plugin for WordPress is vulnerable to SQL injection via several parameters in versions up to, and including, 3.72 due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation of the SQL query. This makes it possible for an attacker to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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 RepairBuddy <= 3.72 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 RepairBuddy the fix is 3.73: builds <= 3.72 are affected, anything from 3.73 onward is not.

Remediation

Update to version 3.73, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to RepairBuddy: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: RepairBuddy 3.73 closes this, and updating the plugin is the step that ends it.
