CVE-2024-13476 identifies a critical SQL Injection vulnerability in the LTL Freight Quotes – GlobalTranz Edition plugin for WordPress, specifically in the 'engtz_wd_save_dropship' AJAX endpoint. This vulnerability exists due to insufficient escaping and lack of proper query preparation on user-supplied parameters, allowing attackers to append arbitrary SQL commands to existing queries. The flaw affects all plugin versions up to and including 2.3.11. Since the endpoint is accessible without authentication, attackers can exploit this remotely over the network without any user interaction. Successful exploitation enables attackers to extract sensitive information from the underlying database, compromising confidentiality. The CVSS v3.1 score is 7.5 (high), reflecting the vulnerability's network attack vector, low attack complexity, no privileges required, and no user interaction needed. Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for attackers aiming to access confidential data. The plugin is used in WordPress environments that support freight quote functionalities, particularly in logistics and transportation sectors. The vulnerability underscores the importance of input validation and parameterized queries in preventing SQL Injection attacks.

The primary impact of CVE-2024-13476 is unauthorized disclosure of sensitive data stored in the affected WordPress plugin's database. Attackers exploiting this vulnerability can extract confidential information such as customer details, freight quotes, shipping data, and potentially other sensitive business information. This can lead to data breaches, loss of customer trust, regulatory penalties, and competitive disadvantage. Since the vulnerability does not affect integrity or availability directly, the main concern is confidentiality compromise. However, attackers could leverage extracted data for further attacks, including phishing or lateral movement within the victim's network. Organizations using this plugin in their logistics or freight management workflows face increased risk of targeted attacks, especially if they handle sensitive or regulated data. The ease of exploitation and lack of required authentication increase the threat level globally, potentially affecting any organization using this plugin without timely mitigation.

1. Immediate action should be to update the LTL Freight Quotes – GlobalTranz Edition plugin to a patched version once available from the vendor. Since no patch links are currently provided, monitor vendor announcements closely. 2. Temporarily disable or restrict access to the 'engtz_wd_save_dropship' AJAX endpoint via web server or application firewall rules to prevent exploitation. 3. Deploy a Web Application Firewall (WAF) with SQL Injection detection and prevention rules tailored to block malicious payloads targeting this endpoint. 4. Conduct a thorough audit of database logs and application logs to detect any suspicious queries or access patterns indicative of exploitation attempts. 5. Implement strict input validation and parameterized queries in custom code or plugin forks if immediate patching is not feasible. 6. Limit exposure by restricting access to the WordPress admin and AJAX endpoints to trusted IP addresses where possible. 7. Educate system administrators and security teams about this vulnerability to ensure rapid response and monitoring. 8. Regularly back up databases and test restoration procedures to mitigate potential data loss from future attacks.
