CVE-2024-13488 is an SQL Injection vulnerability classified under CWE-89 found in the 'LTL Freight Quotes – Estes Edition' WordPress plugin developed by enituretechnology. This vulnerability affects all plugin versions up to and including 3.3.7. The root cause is insufficient escaping and lack of prepared statements for the 'dropship_edit_id' and 'edit_id' parameters, which are user-supplied inputs incorporated directly into SQL queries. Because these parameters are not properly sanitized, an attacker can inject arbitrary SQL commands appended to the existing query. The vulnerability is exploitable remotely without any authentication or user interaction, making it highly accessible to attackers. Successful exploitation allows unauthorized disclosure of sensitive information stored in the backend database, such as customer data, shipping details, or configuration settings. The CVSS 3.1 base score is 7.5 (High), reflecting the network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact with no integrity or availability impact. Although no active exploits have been reported, the widespread use of WordPress and this plugin in freight and logistics sectors increases the risk of targeted attacks. The lack of patches or official fixes at the time of publication necessitates immediate mitigation efforts by affected users.

The primary impact of this vulnerability is unauthorized disclosure of sensitive data from the backend database of affected WordPress sites. Attackers can leverage the SQL Injection flaw to extract confidential information such as customer shipping data, pricing, and internal logistics details, which can lead to privacy violations, competitive intelligence gathering, and regulatory compliance issues. Since the vulnerability requires no authentication, any attacker scanning for vulnerable sites can exploit it remotely, increasing the attack surface. Although the vulnerability does not affect data integrity or availability, the exposure of sensitive data can result in reputational damage, financial losses, and potential legal consequences for organizations. Freight and logistics companies relying on this plugin for quoting services are particularly at risk, as their operational data and client information could be compromised. The absence of known exploits in the wild currently limits immediate widespread impact, but the risk remains significant due to the ease of exploitation.

1. Immediate mitigation should focus on updating the 'LTL Freight Quotes – Estes Edition' plugin to a version that addresses this vulnerability once released by the vendor. 2. Until a patch is available, implement Web Application Firewall (WAF) rules to detect and block SQL Injection attempts targeting the 'dropship_edit_id' and 'edit_id' parameters. 3. Employ input validation and sanitization at the application level to reject suspicious or malformed input for these parameters. 4. Restrict public access to the affected plugin's endpoints if feasible, using IP whitelisting or authentication mechanisms to reduce exposure. 5. Conduct regular security audits and database monitoring to detect unusual query patterns or data access indicative of exploitation attempts. 6. Backup databases frequently and ensure backups are stored securely to enable recovery in case of data compromise. 7. Educate site administrators about the risks of using outdated plugins and the importance of timely updates. 8. Consider isolating the WordPress environment or using containerization to limit the blast radius of potential attacks.
