CVE-2025-4707 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/transaction_add.php file. The vulnerability arises from 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 into the 'prod_name' argument. Successful exploitation could allow unauthorized access to the underlying database, enabling attackers to read, modify, or delete sensitive sales and inventory data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild yet. 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 needed, but with limited impact on confidentiality, integrity, and availability. The lack of a patch or mitigation guidance at this time increases the urgency for affected organizations to implement compensating controls.

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. Exploitation could lead to unauthorized data disclosure, manipulation of transaction records, and potential disruption of business operations. Given the critical role of sales and inventory systems in supply chain management and financial reporting, successful attacks could result in financial losses, regulatory compliance violations (e.g., GDPR breaches due to exposure of personal data), and reputational damage. The remote and unauthenticated nature of the attack vector increases the threat surface, especially for organizations exposing this system to the internet or poorly segmented internal networks. The medium CVSS score suggests moderate impact but the critical rating by the vendor indicates the potential for severe consequences if exploited at scale or combined with other vulnerabilities.

Since no official patches or updates are currently available, European organizations should immediately implement the following mitigations: 1) Restrict external network access to the Campcodes Sales and Inventory System, ensuring it is not directly accessible from the internet. 2) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'prod_name' parameter. 3) Conduct thorough input validation and sanitization on all user-supplied data, especially for the vulnerable endpoint, using parameterized queries or prepared statements if possible. 4) Monitor logs for unusual database queries or errors indicative of injection attempts. 5) Segment the network to isolate the sales and inventory system from critical infrastructure and sensitive data stores. 6) Prepare incident response plans to quickly address any signs of compromise. 7) Engage with the vendor for updates and patches, and plan for timely application once available.
