CVE-2024-13491 is an SQL Injection vulnerability identified in the enituretechnology WordPress plugin 'Small Package Quotes – For Customers of FedEx', affecting all versions up to 4.3.1. The vulnerability stems from insufficient escaping and lack of prepared statements in handling the 'edit_id' and 'dropship_edit_id' parameters, which are user-supplied inputs. This improper neutralization of special SQL elements (CWE-89) allows an unauthenticated attacker to append arbitrary SQL commands to existing queries. As a result, attackers can extract sensitive information from the backend database, potentially including customer data, shipping details, or other confidential business information. The vulnerability is exploitable remotely over the network without any authentication or user interaction, increasing its risk profile. The CVSS 3.1 base score of 7.5 reflects these factors: attack vector is network (AV:N), attack complexity is low (AC:L), no privileges required (PR:N), no user interaction (UI:N), scope unchanged (S:U), and high confidentiality impact (C:H) with no impact on integrity or availability (I:N/A:N). Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime candidate for exploitation once weaponized. The plugin is used primarily by WordPress sites integrating FedEx shipping quotes, making e-commerce and logistics-related websites the main targets. The lack of available patches at the time of disclosure necessitates immediate mitigation steps to prevent data leakage.

The primary impact of CVE-2024-13491 is unauthorized disclosure of sensitive data stored in the affected WordPress site's database. Attackers can exploit the SQL Injection flaw to retrieve confidential information such as customer details, shipping data, pricing, and potentially administrative credentials if stored insecurely. This breach of confidentiality can lead to privacy violations, regulatory non-compliance (e.g., GDPR, CCPA), and reputational damage. Since the vulnerability does not affect integrity or availability, attackers cannot modify or delete data or disrupt services directly via this flaw. However, extracted data can be used for further attacks such as phishing, identity theft, or lateral movement within the victim's network. The ease of exploitation without authentication or user interaction increases the risk of widespread automated attacks. Organizations relying on this plugin for FedEx shipping quotes in their e-commerce workflows face significant exposure, especially if sensitive customer or business data is stored in the database. The lack of known exploits in the wild currently provides a window for proactive mitigation before active exploitation begins.

1. Immediate mitigation should focus on disabling or removing the vulnerable 'Small Package Quotes – For Customers of FedEx' plugin until a secure update is released. 2. Monitor the vendor's official channels for patches or updates addressing CVE-2024-13491 and apply them promptly once available. 3. Implement Web Application Firewall (WAF) rules to detect and block SQL Injection attempts targeting the 'edit_id' and 'dropship_edit_id' parameters. Custom WAF signatures can be created to identify suspicious payloads attempting to inject SQL syntax. 4. Conduct a thorough audit of database access logs and application logs to detect any anomalous queries or unauthorized data access attempts. 5. Restrict database user permissions to the minimum necessary, avoiding excessive privileges that could exacerbate the impact of SQL Injection. 6. Employ parameterized queries and prepared statements in custom code to prevent injection vulnerabilities in other parts of the application. 7. Educate development and security teams about secure coding practices related to input validation and sanitization. 8. Consider isolating the WordPress environment or using containerization to limit the blast radius in case of compromise. 9. Regularly back up databases and verify backup integrity to enable recovery if data is compromised. 10. Review and harden overall WordPress security posture, including timely updates of core, themes, and plugins.
