CVE-2024-6027 in Themify Plugin
Summary
by MITRE • 06/21/2024
The Themify – WooCommerce Product Filter plugin for WordPress is vulnerable to time-based SQL Injection via the ‘conditions’ parameter in all versions up to, and including, 1.4.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers 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-2024-6027 affects the Themify WooCommerce Product Filter plugin for WordPress, representing a critical time-based SQL injection flaw that has been present in all versions up to and including 1.4.9. This security weakness stems from inadequate input validation and sanitization within the plugin's handling of user-supplied data, specifically the 'conditions' parameter that is processed without proper escaping mechanisms. The flaw exists at the intersection of poor database query construction practices and insufficient parameter validation, creating an exploitable pathway for malicious actors to manipulate the underlying SQL execution flow.
The technical implementation of this vulnerability allows unauthenticated attackers to inject malicious SQL code through the 'conditions' parameter, which is then incorporated into existing database queries without proper preparation or sanitization. This time-based SQL injection occurs when the attacker's injected payload causes the database server to delay its response time, enabling the attacker to infer information about the database structure and contents through timing variations in query execution. The vulnerability's impact is particularly severe because it does not require authentication to exploit, making it accessible to anyone who can interact with the affected plugin's functionality.
From an operational perspective, this vulnerability presents a significant risk to WordPress sites utilizing the Themify WooCommerce Product Filter plugin, as it enables attackers to extract sensitive information from the database without requiring any valid credentials or privileged access. The time-based nature of the injection means that attackers can potentially enumerate database contents, user information, product data, and other sensitive elements stored within the WordPress installation's database. This type of information disclosure can lead to further exploitation opportunities, including credential theft, data manipulation, and potential full system compromise.
The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws in software applications, and demonstrates characteristics consistent with the ATT&CK technique T1213.002 for Data from Databases, as it enables unauthorized access to stored data through database manipulation. Organizations should prioritize immediate remediation by updating to the latest version of the plugin where this vulnerability has been addressed, implementing input validation measures, and monitoring for any signs of exploitation attempts. Additionally, network-based intrusion detection systems should be configured to detect anomalous database query patterns that may indicate exploitation of this vulnerability.
