At a glance

CVE-2022-1505 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the RSVPMaker WordPress plugin, affecting versions <= 9.2.6. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 9.2.7; sites on affected versions should update now. Disclosed April 2022, reported by Tobias Kay Dalå (oxnan).

Vulnerability Overview

The RSVPMaker plugin for WordPress is vulnerable to unauthenticated SQL Injection due to missing SQL escaping and parameterization on user supplied data passed to a SQL query in the rsvpmaker-api-endpoints.php file. This makes it possible for unauthenticated attackers to steal sensitive information from the database in versions up to and including 9.2.6.

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 RSVPMaker <= 9.2.6 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. For RSVPMaker the fix is 9.2.7: builds <= 9.2.6 are affected, anything from 9.2.7 onward is not.

Remediation

Update to version 9.2.7, or a newer patched version

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. None of that substitutes for the fix: RSVPMaker 9.2.7 closes this, and updating the plugin is the step that ends it.
