CVE-2025-4711 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/stockin_add.php file. The vulnerability arises due to improper sanitization or validation of the 'prod_name' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring authentication or user interaction, by injecting crafted SQL statements through the 'prod_name' argument. This can lead to unauthorized access to the underlying database, allowing the attacker to read, modify, or delete sensitive data related to sales and inventory records. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been reported in the wild yet. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with attack vector network (remote), low attack complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is rated low to medium, suggesting partial compromise potential rather than full system takeover. However, given the critical nature of sales and inventory data for business operations, exploitation could disrupt business processes and lead to financial losses or data breaches.

For European organizations using the Campcodes Sales and Inventory System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their sales and inventory data. Successful exploitation could result in unauthorized disclosure of sensitive commercial information, manipulation of inventory records, and potential disruption of supply chain and sales operations. This could lead to financial losses, reputational damage, and regulatory compliance issues, especially under GDPR requirements for protecting personal and business data. The remote and unauthenticated nature of the exploit increases the threat level, as attackers can target vulnerable systems over the internet without needing insider access. Organizations relying heavily on this system for critical business functions may face operational downtime and loss of customer trust if exploited. The absence of known active exploits provides a window for mitigation, but the public disclosure necessitates urgent action to prevent potential attacks.

European organizations should immediately assess their exposure to Campcodes Sales and Inventory System version 1.0 and prioritize patching or upgrading to a fixed version once available. In the absence of an official patch, organizations should implement the following mitigations: 1) Apply input validation and parameterized queries or prepared statements in the 'prod_name' parameter to prevent SQL injection. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable endpoint. 3) Restrict external access to the affected application or isolate it within a secure network segment to reduce attack surface. 4) Conduct thorough code reviews and penetration testing focused on SQL injection vectors in the application. 5) Monitor logs and network traffic for suspicious activities related to SQL injection attempts. 6) Educate development and security teams about secure coding practices to prevent similar vulnerabilities. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and application context.
