At a glance

CVE-2022-3919 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Jetpack CRM WordPress plugin, affecting versions <= 5.4.2. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 5.4.3; sites on affected versions should update now. Disclosed November 2022, reported by zhangyunpei.

Vulnerability Overview

The Jetpack CRM plugin for WordPress is vulnerable to Stored Cross-Site Scripting via some of its settings in versions up to, and including, 5.4.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Jetpack CRM <= 5.4.2 takes an account at Administrator level or above. 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 Jetpack CRM the fix is 5.4.3: builds <= 5.4.2 are affected, anything from 5.4.3 onward is not.

Remediation

Update to version 5.4.3, or a newer patched version

How does WordSec protect against this?

An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Jetpack CRM 5.4.3 closes this, and updating the plugin is the step that ends it.
