CVE-2024-12607 in School Management System Plugin
Summary
by MITRE • 03/07/2025
The School Management System for Wordpress plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter of the 'mj_smgt_show_event_task' AJAX action in all versions up to, and including, 92.0.0 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 Custom-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 School Management System for WordPress plugin presents a critical SQL injection vulnerability (CVE-2024-12607) that affects all versions up to and including 92.0.0. This vulnerability resides within the mj_smgt_show_event_task AJAX action and specifically targets the 'id' parameter, creating a pathway for malicious exploitation. The flaw stems from inadequate input sanitization and insufficient query preparation mechanisms that fail to properly escape user-supplied data before incorporating it into database queries. The vulnerability operates under CWE-89 which categorizes it as a classic SQL injection flaw where untrusted data is directly concatenated into SQL statements without proper validation or escaping. Attackers with Custom-level access or higher can exploit this weakness to manipulate existing database queries through crafted input values, effectively bypassing normal authentication and authorization controls. The impact of this vulnerability extends beyond simple data exfiltration as it allows for arbitrary SQL command execution within the database context, potentially enabling full system compromise.
The operational implications of this vulnerability are severe given that it requires only authenticated access at the Custom level, which represents a relatively low privilege threshold for WordPress environments. This means that individuals who have been granted basic user permissions or those who have compromised such accounts can leverage this weakness to extract sensitive information from the database. The attack vector specifically targets the AJAX endpoint which is commonly used for dynamic content loading and user interactions, making the exploitation more stealthy and less likely to trigger standard security monitoring alerts. The vulnerability's persistence across multiple versions indicates a fundamental flaw in the plugin's code architecture rather than a temporary oversight, suggesting that the security measures were not properly implemented at the core level of the application's data handling processes. This weakness creates a persistent threat that could be exploited by both internal and external attackers who gain access to accounts with Custom-level permissions.
Organizations using this plugin must implement immediate mitigations to address the SQL injection vulnerability. The most effective immediate solution involves implementing proper input validation and parameterized queries that prevent user-supplied data from being directly incorporated into SQL statements. The plugin developers should adopt prepared statements with bound parameters, which is the standard industry practice for preventing SQL injection attacks according to OWASP top ten recommendations. Additionally, implementing proper access controls and privilege separation can help limit the impact of potential exploitation by ensuring that even if an attacker gains access to a Custom-level account, they cannot escalate privileges or access sensitive database operations. Network-level monitoring should be enhanced to detect unusual AJAX request patterns and malformed SQL queries that could indicate exploitation attempts. The vulnerability also highlights the importance of regular security audits and code reviews, particularly focusing on database interaction points and user input handling mechanisms. Organizations should also consider implementing web application firewalls and database activity monitoring solutions to provide additional layers of defense against such attacks. The exploitation of this vulnerability could result in data breaches, unauthorized system access, and potential compliance violations, making prompt remediation essential for maintaining the integrity and security of educational institution databases.
