CVE-2024-13483 identifies a critical SQL Injection vulnerability in the LTL Freight Quotes – SAIA Edition WordPress plugin developed by enituretechnology. This vulnerability affects all plugin versions up to and including 2.2.10. The root cause is the improper neutralization of special elements in SQL commands (CWE-89), specifically through the 'edit_id' and 'dropship_edit_id' parameters. These parameters are insufficiently escaped and the SQL queries are not properly prepared, enabling attackers to append arbitrary SQL commands. The vulnerability is exploitable remotely over the network without any authentication or user interaction, as the parameters are accessible to unauthenticated users. Successful exploitation allows attackers to extract sensitive information from the backend database, compromising confidentiality. The CVSS v3.1 score is 7.5 (high), reflecting the ease of exploitation (low attack complexity), no privileges required, and high impact on confidentiality, while integrity and availability remain unaffected. No patches or official fixes are currently linked, and no known exploits have been observed in the wild. However, the exposure of sensitive logistics and freight data could have serious operational and reputational consequences for affected organizations.

The primary impact of this vulnerability is the unauthorized disclosure of sensitive data stored in the database of affected WordPress sites using the LTL Freight Quotes – SAIA Edition plugin. This can include customer information, freight quotes, pricing, and potentially other confidential business data. The breach of confidentiality can lead to competitive disadvantage, regulatory penalties (especially under data protection laws like GDPR or CCPA), and loss of customer trust. Since the vulnerability does not affect data integrity or availability, attackers cannot modify or disrupt services directly, but the data leakage alone poses a significant risk. Given the plugin’s use in freight and logistics quoting, compromised data could also facilitate further targeted attacks or fraud. The ease of exploitation without authentication increases the likelihood of automated scanning and exploitation attempts, especially once public awareness grows. Organizations worldwide that rely on this plugin for freight quoting services are at risk, particularly those with high volumes of sensitive transactional data.

1. Immediate mitigation should involve restricting access to the vulnerable parameters ('edit_id' and 'dropship_edit_id') via web application firewalls (WAFs) or server-level rules to block suspicious SQL injection patterns. 2. Apply strict input validation and sanitization on these parameters, ensuring only expected numeric or alphanumeric values are accepted. 3. Employ parameterized queries or prepared statements in the plugin code to prevent SQL injection. 4. Monitor database logs and web server logs for unusual query patterns or repeated access attempts targeting these parameters. 5. If possible, disable or remove the plugin until a vendor patch is released. 6. Follow up with the vendor for official patches or updates addressing this vulnerability and apply them promptly once available. 7. Conduct regular security audits and vulnerability scans on WordPress installations to detect similar injection flaws. 8. Educate site administrators on the risks of installing unverified plugins and maintaining up-to-date software.
