CVE-2024-9828 in Taskbuilder Plugin
Summary
by MITRE • 11/21/2024
The Taskbuilder WordPress plugin before 3.0.5 does not sanitize user input into the 'load_orders' parameter and uses it in a SQL statement, allowing high privilege users such as admin to perform SQL Injection attacks

The Taskbuilder WordPress plugin vulnerability CVE-2024-9828 represents a critical security flaw that enables authenticated SQL injection attacks against high-privilege users. This vulnerability exists in versions prior to 3.0.5 and specifically targets the 'load_orders' parameter within the plugin's functionality. The issue stems from inadequate input sanitization mechanisms that fail to properly validate and escape user-provided data before incorporating it into database queries. Attackers with administrative privileges can exploit this weakness to execute arbitrary SQL commands against the WordPress database, potentially leading to complete system compromise and unauthorized data access.
The technical implementation of this vulnerability aligns with CWE-89, which classifies SQL injection as a common weakness in software applications. The flaw occurs when the plugin receives user input through the 'load_orders' parameter without proper sanitization or parameterization before executing database operations. This allows malicious actors to manipulate the SQL query structure and inject additional commands that can extract sensitive information, modify database contents, or even execute system-level operations. The vulnerability specifically affects high-privilege users because the plugin's access controls do not adequately restrict the input validation for administrative functions.
From an operational impact perspective, this vulnerability creates significant risk for WordPress installations using the Taskbuilder plugin. Administrators who are compromised can face complete data breaches including user credentials, personal information, and business-critical data stored in the database. The attack vector requires only authentication as an administrator, making it particularly dangerous in environments where admin credentials might be compromised through other means such as credential stuffing or phishing attacks. The potential for privilege escalation and persistent backdoor installation increases the overall threat level significantly.
The mitigation strategy for CVE-2024-9828 involves immediate patching of the Taskbuilder plugin to version 3.0.5 or later, which contains the necessary input sanitization fixes. Organizations should also implement proper input validation and parameterized queries throughout their WordPress installations to prevent similar vulnerabilities. Network monitoring should be enhanced to detect unusual database query patterns that might indicate SQL injection attempts. Additionally, implementing principle of least privilege access controls and regular security audits of WordPress plugins can help prevent exploitation of such vulnerabilities. The ATT&CK framework categorizes this vulnerability under T1078 for valid accounts and T1046 for network service scanning, indicating that exploitation typically involves establishing persistent access through compromised administrative credentials.
