CVE-2024–1207: A Deep Dive into WordPress Plugin Vulnerability

WordPress powers a significant portion of the web, the security of plugins becomes paramount.

Recently, a critical vulnerability, CVE-2024–1207, has been identified in the popular WP Booking Calendar plugin, sending ripples through the WordPress community.

This article aims to shed light on the vulnerability, its potential impact, and actionable steps for mitigation, ensuring your digital presence remains secure and trustworthy.

CVE-2024–1207 is a critical SQL Injection vulnerability discovered in the WP Booking Calendar plugin for WordPress.

This flaw affects all versions up to and including 9.9, posing a significant risk to websites utilizing the plugin​.

Vulnerability Details

The vulnerability arises from insufficient escaping of the calendar_request_params[dates_ddmmyy_csv] parameter and a lack of preparation in the SQL query.

This oversight allows unauthenticated attackers to inject additional SQL queries into the database, potentially accessing sensitive information​.

Example of Possible Injection

Suppose the parameter calendar_request_params[dates_ddmmyy_csv] is used in a web application to fetch calendar events based on dates provided in a CSV (Comma-Separated Values) format, like "01-01-2023,02-01-2023".

If the application constructs SQL queries by directly incorporating user input without proper sanitization or preparation, an attacker could manipulate the parameter to execute malicious SQL code.

For example, an attacker might supply a value like 1-01-2023'; DROP TABLE users; --. If this input is concatenated directly into a SQL query, it could lead to destructive behavior, such as dropping a database table.
