CVE-2025-11109 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Computer Sales and Inventory System. The vulnerability exists in an unspecified function within the file /pages/us_edit.php, specifically when handling the 'ID' parameter during an edit action. An attacker can manipulate this 'ID' argument to inject malicious SQL code, which the system fails to properly sanitize or parameterize. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability has 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 rated as low individually but combined could lead to significant data exposure or modification. Although no known exploits are currently observed in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the Campcodes Computer Sales and Inventory System, a specialized software product used for managing computer sales and inventory operations. The lack of patches or mitigation links suggests that the vendor has not yet released an official fix, making affected systems vulnerable until remediation is applied.

For European organizations using Campcodes Computer Sales and Inventory System 1.0, this vulnerability poses a tangible risk of unauthorized data access and manipulation. Successful exploitation could lead to exposure of sensitive sales, inventory, and customer data, potentially violating GDPR requirements on data protection and privacy. Integrity of inventory records could be compromised, leading to operational disruptions and financial inaccuracies. The ability to execute arbitrary SQL commands remotely without authentication increases the threat level, as attackers could escalate the attack to extract confidential business intelligence or disrupt availability by deleting or corrupting data. Given the public availability of exploits, opportunistic attackers or cybercriminal groups could target vulnerable European businesses, especially small to medium enterprises relying on this software. The absence of patches means organizations must rely on compensating controls, increasing operational overhead and risk. Additionally, reputational damage and regulatory penalties could result from data breaches stemming from this vulnerability.

1. Immediate mitigation should include restricting network access to the affected application, ideally isolating it behind firewalls or VPNs to limit exposure to untrusted networks. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'ID' parameter in /pages/us_edit.php. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize all user inputs, especially the 'ID' parameter. 4. If possible, upgrade to a newer, patched version of the Campcodes system once available. Until then, consider disabling or restricting the vulnerable functionality if business operations allow. 5. Monitor logs for unusual database queries or errors indicative of SQL injection attempts. 6. Educate IT and security teams about this vulnerability and the importance of rapid incident response. 7. Regularly back up critical data to enable recovery in case of data corruption or deletion. 8. Engage with the vendor for timelines on patch releases and request security advisories.
