CVE-2024-13480 is an SQL Injection vulnerability classified under CWE-89 found in the WordPress plugin 'LTL Freight Quotes – For Customers of FedEx Freight' developed by enituretechnology. The vulnerability affects all versions up to and including 3.4.1. It stems from insufficient escaping and lack of proper preparation of SQL queries involving the 'edit_id' and 'dropship_edit_id' parameters. These parameters accept user input that is directly concatenated into SQL statements without adequate sanitization or use of parameterized queries, enabling attackers to append arbitrary SQL commands. This flaw allows unauthenticated attackers to execute unauthorized SQL queries, potentially extracting sensitive information from the backend database. The vulnerability has a CVSS v3.1 score of 7.5 (high severity), with an attack vector of network (remote), no privileges required, and no user interaction needed. The scope is unchanged, affecting only the vulnerable plugin component. No known exploits have been observed in the wild yet, but the vulnerability's nature makes it a prime target for attackers seeking to compromise data confidentiality. The plugin is used by customers of FedEx Freight, indicating a niche but critical user base in the logistics and freight sector. The lack of available patches at the time of publication increases the urgency for mitigations or vendor updates.

The primary impact of this vulnerability is the unauthorized disclosure of sensitive data stored in the plugin's database tables. Attackers can leverage the SQL Injection flaw to extract confidential information such as customer details, freight quotes, shipping data, or other business-critical information. This can lead to data breaches, loss of customer trust, and potential regulatory penalties depending on the nature of the exposed data. Since the vulnerability does not affect data integrity or availability directly, attackers cannot modify or delete data or cause denial of service through this flaw alone. However, the exposure of sensitive information can facilitate further attacks, including phishing, identity theft, or corporate espionage. Organizations relying on this plugin for freight quoting and logistics management are at risk of operational disruption if sensitive data leaks. The vulnerability's ease of exploitation without authentication or user interaction increases the likelihood of automated attacks and scanning by threat actors. Given the plugin's association with FedEx Freight customers, the impact extends to supply chain security and logistics operations, which are critical for many businesses worldwide.

1. Immediate mitigation involves disabling or removing the vulnerable plugin until a patched version is released by enituretechnology. 2. Monitor official vendor channels for security updates or patches and apply them promptly once available. 3. Implement Web Application Firewall (WAF) rules specifically targeting SQL Injection attempts on the 'edit_id' and 'dropship_edit_id' parameters to block malicious payloads. 4. Conduct thorough input validation and sanitization on all user-supplied data at the application level, employing parameterized queries or prepared statements to prevent SQL Injection. 5. Restrict database user permissions associated with the plugin to the minimum necessary, preventing unauthorized data access or modification. 6. Regularly audit logs for suspicious activity related to these parameters to detect exploitation attempts early. 7. Educate administrators and developers on secure coding practices and the risks of SQL Injection vulnerabilities. 8. Consider network segmentation and limiting external access to the WordPress management interface to reduce exposure. 9. Backup critical data regularly to enable recovery in case of compromise. These steps collectively reduce the risk and impact of exploitation while awaiting official patches.
