CVE-2025-4502 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Sales and Inventory System, specifically within the /pages/creditor_add.php file. This vulnerability allows an unauthenticated remote attacker to manipulate SQL queries by injecting malicious input into the creditor addition functionality. The injection flaw arises from insufficient input validation or improper sanitization of user-supplied data before it is incorporated into SQL statements. Exploiting this vulnerability can enable attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. Since the attack vector is remote and requires no authentication or user interaction, the vulnerability is highly exploitable. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with network attack vector, low complexity, no privileges required, and no user interaction needed. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L). Although no known exploits are reported in the wild yet, the public disclosure increases the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the threat. Organizations using Campcodes Sales and Inventory System 1.0 should consider this vulnerability a significant risk to their database security and overall system integrity.

For European organizations, the exploitation of CVE-2025-4502 could result in unauthorized access to sensitive financial and inventory data managed by the Campcodes system. This may lead to data breaches involving customer information, supplier details, and transactional records, potentially violating GDPR requirements and incurring regulatory penalties. The integrity of sales and inventory data could be compromised, disrupting business operations and financial reporting accuracy. Availability impacts, although limited, could cause temporary denial of service or data corruption, affecting supply chain management and order fulfillment. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to establish persistent footholds or pivot within the network, increasing the risk of broader compromise. European companies relying on this software for critical business functions face operational, reputational, and compliance risks if this vulnerability is exploited.

Immediate mitigation steps include implementing strict input validation and parameterized queries or prepared statements in the creditor_add.php module to prevent SQL injection. Organizations should audit their Campcodes Sales and Inventory System installations and restrict external access to the affected application, ideally limiting it to trusted internal networks or VPNs. Deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting creditor_add.php can provide temporary protection. Monitoring database logs for suspicious queries and unusual activity is critical to early detection. Since no official patch is currently available, organizations should engage with the vendor for updates or consider upgrading to a newer, secure version if available. Additionally, conducting regular security assessments and penetration tests focusing on web application vulnerabilities will help identify and remediate similar issues proactively.
