At a glance

CVE-2022-0769 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Users Ultra Membership, Users Community and Member Profiles With PayPal Integration Plugin WordPress plugin, affecting versions <= 3.1.0. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2022, reported by cydave.

Vulnerability Overview

The Users Ultra WordPress plugin through 3.1.0 fails to properly sanitize and escape the data_target parameter before it is being interpolated in an SQL statement and then executed via the rating_vote AJAX action (available to both unauthenticated and authenticated users), leading to an SQL Injection.

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 Users Ultra Membership, Users Community and Member Profiles With PayPal Integration Plugin <= 3.1.0 takes no account at all. 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. No fixed build of this plugin is recorded for Users Ultra Membership, Users Community and Member Profiles With PayPal Integration Plugin yet, so installs running <= 3.1.0 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
