CVE-2024-1990 in RegistrationMagic Plugin
Summary
by MITRE • 04/10/2024
The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to blind SQL Injection via the ‘id’ parameter of the RM_Form shortcode in all versions up to, and including, 5.3.1.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The vulnerability identified as CVE-2024-1990 affects the RegistrationMagic plugin for WordPress, specifically targeting versions up to and including 5.3.1.0. This represents a critical security flaw that enables authenticated attackers with contributor-level privileges or higher to execute blind SQL injection attacks against the affected WordPress installation. The vulnerability manifests through the 'id' parameter within the RM_Form shortcode, which fails to properly sanitize user-supplied input before incorporating it into database queries.
The technical implementation of this vulnerability stems from inadequate input validation and parameter sanitization practices within the plugin's codebase. When the 'id' parameter is processed through the RM_Form shortcode, the plugin does not employ proper prepared statements or sufficient escaping mechanisms to prevent malicious SQL code from being executed as part of the database query. This flaw falls under the CWE-89 category of SQL Injection, specifically manifesting as a blind SQL injection variant where attackers cannot directly see query results but can infer information through response timing or conditional execution patterns.
The operational impact of this vulnerability is significant as it allows authenticated attackers to extract sensitive information from the WordPress database without requiring administrative privileges. Attackers with contributor-level access can leverage this vulnerability to access user credentials, personal information, payment data, and other sensitive database contents. The blind nature of the injection means that attackers can systematically extract data by crafting queries that produce different responses based on boolean conditions, making it particularly dangerous for data exfiltration purposes. This vulnerability directly aligns with ATT&CK technique T1213.002 for Data from Information Repositories, as it enables unauthorized access to stored data within the WordPress database.
Mitigation strategies for this vulnerability must include immediate plugin updates to versions that address the SQL injection flaw, as well as implementing proper input validation and parameterized queries throughout the application. Administrators should also consider implementing network-level protections such as web application firewalls and database query monitoring to detect suspicious SQL patterns. The principle of least privilege should be enforced by limiting user permissions to the minimum required for their role, and regular security audits should be conducted to identify similar vulnerabilities in other plugins or custom code. Additionally, database access controls should be configured to limit the privileges of the application user account, reducing the potential impact of successful SQL injection attacks.
