The ELEX WooCommerce WordPress Plugin version 1.4.3 contains a SQL Injection vulnerability. SQL Injection (SQLi) is a critical web application security flaw that allows an attacker to manipulate backend SQL queries by injecting malicious input through user-controllable parameters. In this case, the vulnerability resides within the ELEX WooCommerce plugin, which integrates with WordPress to extend WooCommerce functionality. Although the exact injection vector and affected parameters are not detailed, the presence of SQLi implies that an attacker could craft specially crafted requests to execute arbitrary SQL commands on the underlying database. This could lead to unauthorized data disclosure, data modification, or even full compromise of the WordPress site if the database contains sensitive information or if the attacker can escalate privileges. The tags include "rce" (remote code execution), which suggests that the SQLi might be leveraged to achieve code execution on the server, possibly through advanced exploitation techniques such as stacked queries or leveraging database functions to write files or execute system commands. The vulnerability is classified as medium severity by the source, but no CVSS score is provided. There are no known exploits in the wild at the time of reporting, and no patch links are provided, indicating that a fix might not yet be available or publicly disclosed. The lack of affectedVersions data means it is unclear if this affects only version 1.4.3 or other versions as well. Given the widespread use of WooCommerce and WordPress in e-commerce websites, this vulnerability could be significant if exploited.

For European organizations, especially those operating e-commerce platforms using WooCommerce and the ELEX plugin, this vulnerability poses a risk of data breach, including customer personal data, payment information, and order details. Exploitation could lead to unauthorized access to sensitive business data, financial loss, reputational damage, and potential regulatory penalties under GDPR due to data exposure. Additionally, if the vulnerability is chained to achieve remote code execution, attackers could gain full control over the web server, leading to website defacement, malware distribution, or use as a pivot point for further network intrusion. This risk is heightened for small and medium enterprises (SMEs) that may lack robust security monitoring or timely patch management. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers often develop exploits rapidly once vulnerabilities are disclosed.

European organizations should immediately audit their WordPress installations to identify if the ELEX WooCommerce plugin version 1.4.3 is in use. If so, they should consider temporarily disabling the plugin or restricting access to affected endpoints until a patch is available. Implementing Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting WooCommerce plugins can provide interim protection. Organizations should also review and harden database user permissions to minimize the impact of any SQL injection, ensuring the database user has the least privileges necessary. Monitoring web server and application logs for suspicious input patterns or anomalies related to SQL queries is critical for early detection. Additionally, organizations should subscribe to vendor advisories and security mailing lists to promptly apply patches once released. Conducting security assessments and penetration testing focused on plugin vulnerabilities can help identify other potential weaknesses. Finally, enforcing strong input validation and output encoding practices in custom code interacting with WooCommerce plugins can reduce injection risks.
