CVE-2025-4710 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/transaction.php file. The vulnerability arises from improper sanitization or validation of the 'cid' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The injection can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the system's data. Although the CVSS 4.0 base score is 6.9 (medium severity), the vulnerability's characteristics—network exploitable, no privileges or user interaction needed—indicate a significant risk. The lack of a patch or mitigation from the vendor at the time of disclosure increases the threat surface. The exploit has been publicly disclosed, which raises the likelihood of exploitation attempts. The affected system is used for sales and inventory management, making it a critical component for business operations, and any compromise could disrupt supply chain and financial processes.

For European organizations using Campcodes Sales and Inventory System 1.0, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized access to sensitive sales and inventory data, including customer information, pricing, stock levels, and transaction records. This exposure could result in financial losses, reputational damage, and regulatory non-compliance, especially under GDPR requirements for protecting personal data. Additionally, attackers could manipulate inventory data, causing operational disruptions, incorrect stock management, and potential supply chain failures. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, potentially affecting multiple organizations simultaneously. Given the critical role of sales and inventory systems in business continuity, exploitation could also lead to denial of service or data integrity issues, impacting revenue and customer trust.

Organizations should immediately conduct an inventory to identify any deployments of Campcodes Sales and Inventory System version 1.0. Until an official patch is released, implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'cid' parameter in /pages/transaction.php. 2) Restrict access to the application to trusted networks or VPNs to reduce exposure. 3) Conduct input validation and sanitization at the application or proxy level to filter malicious inputs. 4) Monitor logs for unusual database queries or repeated access attempts to the vulnerable endpoint. 5) If possible, isolate the database with least privilege principles, limiting the database user permissions to prevent data manipulation beyond what is necessary. 6) Prepare for rapid patch deployment once the vendor releases an update. 7) Educate IT and security teams about the vulnerability and ensure incident response plans are updated to handle potential exploitation.
