CVE-2024-50479 identifies a Blind SQL Injection vulnerability in the Woocommerce Quote Calculator plugin developed by chenyenming, affecting versions up to 1.1. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing attackers to inject arbitrary SQL code into database queries. Blind SQL Injection means that attackers cannot directly see the query results but can infer data by observing application behavior or response times. This type of injection can be exploited to extract sensitive information, modify database contents, or escalate privileges within the application. The plugin is used within WooCommerce, a widely adopted e-commerce platform on WordPress, to provide quote calculation features. Since the plugin improperly sanitizes or escapes user-supplied input before incorporating it into SQL statements, attackers can craft malicious payloads that manipulate backend database queries. No CVSS score has been assigned yet, and no patches or fixes have been published, leaving installations vulnerable. Exploitation does not require user interaction but may require the attacker to access the vulnerable plugin's interface or send crafted requests to it. The lack of known exploits in the wild suggests this vulnerability is newly disclosed, but the risk remains significant given the nature of SQL injection attacks. The vulnerability primarily threatens the confidentiality and integrity of data stored in the database, including customer information, quotes, and order details.

The impact of CVE-2024-50479 on organizations using the Woocommerce Quote Calculator plugin can be severe. Successful exploitation could lead to unauthorized disclosure of sensitive customer and business data, including personal identifiable information and pricing details. Attackers may also alter or delete data, disrupting business operations and undermining data integrity. This could result in financial losses, reputational damage, and regulatory compliance violations, especially for organizations subject to data protection laws like GDPR or CCPA. Since WooCommerce powers a significant portion of e-commerce websites globally, the vulnerability could affect a wide range of businesses, from small online stores to larger enterprises. The blind nature of the SQL injection makes detection harder, potentially allowing attackers to maintain stealthy access over time. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network, including privilege escalation or lateral movement. The absence of an official patch increases the window of exposure, emphasizing the need for immediate mitigation.

To mitigate CVE-2024-50479, organizations should first verify if they are using the affected versions (up to 1.1) of the Woocommerce Quote Calculator plugin. Since no official patch is currently available, immediate steps include: 1) Temporarily disabling or uninstalling the vulnerable plugin to eliminate the attack surface. 2) Implementing Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection payloads targeting the plugin's endpoints. 3) Restricting access to the plugin's administrative or quote calculation interfaces via IP whitelisting or VPN to limit exposure. 4) Conducting thorough input validation and sanitization on all user inputs related to the plugin, if custom code modifications are feasible. 5) Monitoring web server and database logs for unusual or suspicious query patterns indicative of SQL injection attempts. 6) Preparing for patch deployment by closely following vendor announcements or community advisories for updates or fixes. 7) Educating development and security teams about the risks of SQL injection and secure coding practices to prevent similar vulnerabilities in the future. These targeted actions go beyond generic advice by focusing on immediate risk reduction and proactive detection tailored to this specific plugin vulnerability.
