CVE-2025-7537 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/product_update.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the underlying database. This could lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability does not require any authentication or user interaction, making it highly exploitable. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with an attack vector of network (remote), low attack complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but present, as the vulnerability allows limited control over the database. Although no known exploits are currently in the wild, the public disclosure of the exploit code increases the risk of exploitation. The lack of available patches or mitigation from the vendor further exacerbates the threat. Given that the Campcodes Sales and Inventory System is used for managing sales and inventory data, exploitation could disrupt business operations, lead to financial losses, and expose sensitive commercial information.

For European organizations using the Campcodes Sales and Inventory System version 1.0, this vulnerability poses a significant risk. Successful exploitation could result in unauthorized access to sensitive sales and inventory data, potentially leading to data breaches involving customer information, pricing, and stock levels. This could damage the organization's reputation and result in regulatory penalties under GDPR due to exposure of personal or business-critical data. Additionally, manipulation of inventory data could disrupt supply chain operations, causing financial and operational impacts. The remote and unauthenticated nature of the attack increases the likelihood of exploitation, especially in organizations with internet-facing instances of the system. The absence of patches means organizations must rely on immediate mitigations to prevent exploitation. Given the interconnected nature of European supply chains, disruption in one organization could have cascading effects on partners and customers across the region.

Organizations should immediately audit their use of the Campcodes Sales and Inventory System to identify any instances of version 1.0 in use, especially those exposed to external networks. As no official patch is currently available, the following specific mitigations are recommended: 1) Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'ID' parameter on /pages/product_update.php. 2) Restrict network access to the application to trusted internal IP addresses or VPNs to reduce exposure. 3) Conduct input validation and sanitization at the application or proxy level to filter out malicious input. 4) Monitor logs for unusual or suspicious database queries or access patterns indicative of exploitation attempts. 5) If possible, isolate the database with strict access controls and limit the database user permissions to the minimum necessary to reduce potential damage. 6) Plan for an urgent upgrade or replacement of the vulnerable system once a patch or vendor fix becomes available. 7) Educate IT and security teams about the vulnerability and the importance of rapid response to any suspicious activity related to this system.
