CVE-2024-0566 is a high-severity SQL Injection vulnerability (CWE-89) found in the Smart Manager WordPress plugin versions prior to 8.28.0. The vulnerability arises because the plugin fails to properly sanitize and escape a parameter before incorporating it into a SQL query. This improper handling allows an attacker with high privileges, such as an administrator, to inject malicious SQL code. Exploiting this flaw could enable the attacker to manipulate the backend database, leading to unauthorized data access, data modification, or even deletion. The vulnerability does not require user interaction but does require the attacker to have administrative privileges on the WordPress site, which limits the initial attack surface but significantly increases the potential damage if exploited. The CVSS 3.1 base score of 7.2 reflects the high impact on confidentiality, integrity, and availability, combined with a low attack complexity and network attack vector. No known exploits are currently reported in the wild, but the presence of this vulnerability in a widely used WordPress plugin makes it a critical concern for site administrators. The lack of a patch link suggests that users should monitor vendor updates closely and apply patches as soon as they become available.

For European organizations, this vulnerability poses a significant risk, especially for those relying on WordPress sites with the Smart Manager plugin installed. Successful exploitation could lead to unauthorized disclosure of sensitive data, including personal data protected under GDPR, resulting in legal and financial repercussions. Data integrity could be compromised, affecting business operations and trustworthiness of the website. Availability could also be impacted if attackers manipulate or delete critical data. Given the requirement for administrative privileges, the threat is primarily from insider threats or attackers who have already compromised an admin account. However, once exploited, the consequences could be severe, including data breaches, defacement, or complete site takeover. This could affect e-commerce platforms, corporate websites, and any service relying on WordPress for content management, which are common across European enterprises and public sector organizations.

European organizations should immediately verify if the Smart Manager plugin is installed and identify the version in use. Until an official patch is released, restrict administrative access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. Conduct regular audits of admin accounts and monitor for unusual database queries or activity indicative of SQL injection attempts. Employ Web Application Firewalls (WAFs) with rules specifically targeting SQL injection patterns to provide an additional layer of defense. Additionally, implement strict input validation and parameterized queries where possible in custom code interacting with the plugin. Backup WordPress databases regularly and ensure backups are stored securely to enable recovery in case of data tampering or loss. Stay updated with vendor announcements for patches and apply them promptly once available.
