CVE-2025-4814 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/supplier_add.php file. The vulnerability arises from improper sanitization or validation of the 'Name' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring authentication or user interaction, allowing them to inject crafted SQL commands directly into the backend database queries. This can lead to unauthorized data access, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 score is 6.9, indicating a medium severity level, reflecting the ease of exploitation (network vector, no privileges or user interaction needed) but with limited impact on confidentiality, integrity, and availability (each rated low).

For European organizations using the Campcodes Sales and Inventory System 1.0, this vulnerability poses a significant risk to business operations and sensitive data. Exploitation could lead to unauthorized access to supplier and inventory data, potentially resulting in data breaches, financial losses, and operational disruptions. Given the system's role in managing sales and inventory, attackers might manipulate stock records or supplier information, affecting supply chain integrity and causing cascading effects on order fulfillment and customer satisfaction. Additionally, compromised systems could be leveraged as entry points for broader network intrusions. The public disclosure of the vulnerability increases the urgency for European entities to assess and remediate the issue promptly to avoid reputational damage and regulatory penalties under frameworks like GDPR.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Applying strict input validation and sanitization on the 'Name' parameter at the application level to block SQL metacharacters and suspicious patterns; 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting /pages/supplier_add.php; 3) Restricting database user permissions to the minimum necessary to limit the impact of a successful injection; 4) Monitoring logs for unusual database queries or errors indicative of injection attempts; 5) Isolating the affected system within the network to reduce exposure; and 6) Planning and prioritizing an upgrade or patch deployment once the vendor releases a fix. Additionally, conducting security awareness training for developers and administrators on secure coding and vulnerability management is recommended.
