CVE-2025-6489 is a critical SQL Injection vulnerability identified in the itsourcecode Agri-Trading Online Shopping System version 1.0. The vulnerability resides in the /transactionsave.php file, specifically in the handling of the 'del' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code into the backend database queries. This injection flaw allows the attacker to interfere with the queries executed by the application, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability requires no authentication or user interaction, making it exploitable by any remote attacker with network access to the affected system. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation (network accessible, no privileges required) but limited impact on confidentiality, integrity, and availability (each rated low). The vulnerability does not require user interaction and affects the system's core transaction processing component, which is critical for the integrity of trading operations. Although no public exploits are currently known in the wild, the disclosure of the vulnerability and the availability of technical details increase the risk of exploitation. The lack of patches or mitigation guidance from the vendor further exacerbates the threat. Given the nature of the vulnerability, attackers could leverage it to extract sensitive customer or transaction data, manipulate transaction records, or disrupt the normal operation of the trading platform, potentially causing financial loss and reputational damage to affected organizations.

For European organizations using the itsourcecode Agri-Trading Online Shopping System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of transaction data. Exploitation could lead to unauthorized disclosure of sensitive agricultural trading information, manipulation of transaction records, and disruption of business operations. This could result in financial losses, regulatory compliance issues (especially under GDPR due to potential exposure of personal data), and erosion of customer trust. Given the critical role of agriculture and food supply chains in Europe, disruption or data compromise in such systems could have broader economic implications. Organizations relying on this software for online trading must consider the risk of data breaches and operational downtime, which could affect supply chain continuity and market stability. The medium CVSS score may underestimate the real-world impact if attackers chain this vulnerability with others or use it as a foothold for further attacks.

1. Immediate mitigation should include restricting external access to the /transactionsave.php endpoint through network segmentation and firewall rules to limit exposure. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'del' parameter. 3. Conduct a thorough code review and sanitize all user inputs, particularly the 'del' parameter, using parameterized queries or prepared statements to prevent SQL injection. 4. If possible, upgrade to a patched version of the software once available or apply vendor-provided patches promptly. 5. Monitor database logs and application logs for unusual query patterns or anomalies indicative of SQL injection attempts. 6. Employ runtime application self-protection (RASP) tools to detect and block injection attacks in real-time. 7. Educate development and operations teams about secure coding practices and the importance of input validation. 8. As a temporary workaround, disable or limit the functionality that processes the 'del' parameter if it is not critical to business operations. 9. Regularly back up transaction data and verify the integrity of backups to enable recovery in case of data tampering.
