Description

CVE-2024-11726 affects the Appointment Booking Calendar Plugin and Scheduling Plugin – BookingPress plugin for WordPress. This vulnerability allows authenticated attackers, with Contributor-level access or higher, to execute SQL Injection attacks via the 'category' parameter within the 'bookingpress_form' shortcode. The vulnerability stems from insufficient escaping of user-supplied parameters and inadequate preparation of the existing SQL query. This flaw enables attackers to append malicious SQL commands to existing queries, potentially extracting sensitive information from the database.

While the CVSS score is 6.5, the SOCRadar Vulnerability Risk Score (SVRS) is 46, indicating a moderate risk level. Although not immediately critical, this vulnerability necessitates attention and mitigation measures due to its potential impact.

Key Insights

• Impact: This vulnerability allows attackers with Contributor-level access or higher to potentially steal sensitive data from the WordPress database, potentially including user credentials, financial information, and other confidential data.
• Exploitation: The vulnerability is exploitable via the 'bookingpress_form' shortcode, which is commonly used in WordPress websites for booking appointments and scheduling events. Attackers can craft malicious input within the 'category' parameter to execute their SQL injection commands.
• Attack Vector: Authenticated attackers with Contributor-level access or higher can exploit this vulnerability. This signifies that attackers need to gain initial access to the WordPress website before exploiting this specific vulnerability.
• Affected Versions: All versions of the BookingPress plugin up to and including 1.1.21 are vulnerable. Users must update to a patched version to mitigate this risk.

Mitigation Strategies

1. Update the Plugin: Immediately update the BookingPress plugin to the latest version. This is the most effective way to address the vulnerability.
2. Apply Input Validation: Implement robust input validation and sanitization practices for all user inputs, particularly those used within the 'bookingpress_form' shortcode. This helps prevent malicious data from reaching the database.
3. Limit User Privileges: Implement the principle of least privilege. Ensure that users only have access to the functionalities and data they require for their roles. This reduces the potential impact of an attack by limiting the attacker's access to sensitive information.
4. Web Application Firewall (WAF): Consider implementing a WAF to protect your WordPress website from various attacks, including SQL injection. A WAF can detect and block malicious traffic, offering an additional layer of security.
