CVE-2025-4899 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System. The vulnerability exists in the /pages/transaction_update.php file, specifically through improper handling of the 'ID' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. The vulnerability requires no authentication or user interaction, making it highly exploitable over the network. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated low individually but combined could lead to significant data exposure or corruption. No patches or fixes have been disclosed yet, and no known exploits are currently active in the wild, though public disclosure increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the product, which is a sales and inventory management system likely used by small to medium enterprises for transaction processing and inventory control. SQL Injection vulnerabilities are among the most severe web application security issues, as they can lead to data leakage, unauthorized data manipulation, or complete system compromise depending on database permissions and application architecture.

For European organizations using Campcodes Sales and Inventory System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive business data, including sales transactions, inventory records, and potentially customer information. Exploitation could result in unauthorized data disclosure, data tampering, or disruption of business operations. Given that the vulnerability can be exploited remotely without authentication, attackers could leverage this flaw to gain footholds in corporate networks, potentially leading to broader compromise. The impact is particularly critical for organizations in sectors with strict data protection regulations such as GDPR, where data breaches can result in substantial fines and reputational damage. Additionally, disruption of inventory and sales systems can affect supply chain management and financial reporting, causing operational and financial losses.

Organizations should immediately assess their usage of Campcodes Sales and Inventory System version 1.0 and plan for an upgrade or patch once available. In the absence of an official patch, applying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'ID' parameter in /pages/transaction_update.php can reduce risk. Input validation and parameterized queries should be implemented by developers to sanitize and properly handle user inputs. Network segmentation and restricting external access to the affected application can limit exposure. Regular monitoring of logs for suspicious SQL syntax or unusual database queries is advised to detect exploitation attempts early. Organizations should also conduct penetration testing focused on SQL injection vectors and ensure backups are current to enable recovery if data integrity is compromised.
