Booking Calendar <= 9.9 - Unauthenticated SQL Injection

9.8
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2024-1207
CVSS 9.8 (Critical)
Publicly Published February 7, 2024
Last Updated February 8, 2024
Researcher Muhammad Hassham Nagori - IKZERO

Description

The WP Booking Calendar plugin for WordPress is vulnerable to SQL Injection via the 'calendar_request_params[dates_ddmmyy_csv]' parameter in all versions up to, and including, 9.9 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.
