CVE-2025-4709 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/transaction_del.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without requiring user interaction or privileges. The vulnerability is classified with a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting that while the attacker can access or modify some data, the overall system compromise is constrained. No patches or exploit code are currently publicly available, and no known active exploitation has been reported. However, the public disclosure of the vulnerability increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the Campcodes Sales and Inventory System, a product used for managing sales and inventory transactions, which may be deployed in small to medium-sized enterprises. The SQL Injection vulnerability could allow attackers to extract sensitive business data, manipulate transaction records, or disrupt inventory management processes, potentially leading to financial loss or operational disruption.

For European organizations using Campcodes Sales and Inventory System 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their sales and inventory data. Exploitation could lead to unauthorized data disclosure, such as customer information, pricing, or stock levels, which may violate GDPR requirements and result in regulatory penalties. Integrity violations could corrupt transaction records, causing financial discrepancies and operational inefficiencies. Availability impact is limited but could still disrupt business processes if attackers manipulate or delete critical data. Given the remote exploitability without authentication, attackers could target vulnerable systems over the internet, increasing the risk for organizations with externally accessible instances. The medium severity rating suggests a moderate threat level; however, the business impact could be significant depending on the organization's reliance on this system and the sensitivity of the data processed. Additionally, the lack of available patches means organizations must rely on other mitigations until an official fix is released.

1. Immediate mitigation should include implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'ID' parameter in /pages/transaction_del.php. 2. Conduct a thorough audit of all input validation and sanitization mechanisms within the application, focusing on parameters used in SQL queries. 3. Employ parameterized queries or prepared statements in the application code to prevent SQL injection vulnerabilities. 4. Restrict network access to the Sales and Inventory System to trusted internal networks or VPNs, minimizing exposure to the internet. 5. Monitor application logs for unusual database query patterns or error messages indicative of injection attempts. 6. Engage with the vendor (Campcodes) to obtain or request an official patch or update addressing this vulnerability. 7. As a temporary measure, consider disabling or restricting access to the vulnerable transaction deletion functionality if feasible without disrupting critical operations. 8. Educate IT and security teams about this vulnerability to ensure rapid detection and response to any exploitation attempts.
