At a glance

CVE-2024-3605 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WP Hotel Booking WordPress plugin, affecting versions <= 2.1.0. It carries a CVSS score of 10.0 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.1.1; sites on affected versions should update now. Disclosed June 2024, reported by Krzysztof Zając.

Vulnerability Overview

The WP Hotel Booking plugin for WordPress is vulnerable to SQL Injection via the 'room_type' parameter of the /wphb/v1/rooms/search-rooms REST API endpoint in all versions up to, and including, 2.1.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers 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 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')

WP Hotel Booking <= 2.1.0 carries this weakness at room_type, and reaching it 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 WP Hotel Booking the fix is 2.1.1: builds <= 2.1.0 are affected, anything from 2.1.1 onward is not.

Remediation

Update to version 2.1.1, 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: WP Hotel Booking 2.1.1 closes this, and updating the plugin is the step that ends it.
