CVE-2024-39071 identifies a critical SQL Injection vulnerability in Fujian Kelixun software versions up to 7.6.6.4391, specifically within the send_event.php script. SQL Injection (CWE-94) occurs when untrusted input is improperly sanitized before being incorporated into SQL queries, allowing attackers to manipulate the database backend. This vulnerability is remotely exploitable over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is severe, enabling attackers to read, modify, or delete sensitive data, execute administrative operations on the database, or disrupt service availability. The lack of a patch link suggests that a fix may not yet be publicly available, increasing urgency for defensive measures. Although no active exploits have been reported, the critical CVSS score of 9.8 highlights the potential for devastating consequences if weaponized. The vulnerability affects a widely used product in certain sectors, making it a high-priority issue for organizations relying on Fujian Kelixun software. Mitigation requires immediate attention to input validation, database security hardening, and monitoring for anomalous activity.

The potential impact of CVE-2024-39071 is substantial for organizations using vulnerable Fujian Kelixun versions. Successful exploitation can lead to full compromise of the backend database, resulting in unauthorized disclosure of sensitive information, data tampering, or deletion. This can disrupt business operations, cause regulatory compliance violations, and damage organizational reputation. The vulnerability’s remote, unauthenticated nature means attackers can exploit it without prior access, increasing the attack surface significantly. Critical infrastructure or sectors relying on this software may face operational outages or data breaches, potentially affecting national security or public safety. The absence of known exploits currently provides a window for proactive defense, but the high severity score indicates that attackers will likely develop exploits soon. Organizations worldwide must treat this vulnerability as a critical risk to their data integrity and availability.

To mitigate CVE-2024-39071 effectively, organizations should: 1) Immediately check for and apply any official patches or updates from Fujian Kelixun once available. 2) Implement strict input validation and sanitization on all parameters passed to send_event.php to prevent malicious SQL code injection. 3) Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user input into SQL commands. 4) Restrict database user privileges to the minimum necessary, preventing the application from executing high-privilege commands. 5) Monitor database logs and web application logs for unusual query patterns or error messages indicative of injection attempts. 6) Use Web Application Firewalls (WAFs) with rules targeting SQL Injection signatures to block exploit attempts. 7) Conduct regular security assessments and code reviews focusing on input handling and database interactions. 8) Isolate critical database servers and limit network exposure to reduce attack vectors. These steps go beyond generic advice by focusing on immediate code-level and operational controls tailored to this vulnerability’s characteristics.
