CVE-2025-5079 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Shopping Portal. The vulnerability resides in the /admin/updateorder.php endpoint, specifically in the processing of the 'remark' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code into the backend database queries. This injection flaw allows unauthorized actors to interfere with the application's database operations, potentially leading to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability requires no authentication or user interaction, making it highly exploitable over the network. Despite the critical nature of the vulnerability, the CVSS 4.0 base score is 6.9 (medium severity) due to limited impact on confidentiality, integrity, and availability (each rated low), and no scope change. No known exploits are currently reported in the wild, but public disclosure increases the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the threat level. Given the vulnerability affects an administrative interface, successful exploitation could allow attackers to alter order data, access sensitive customer information, or disrupt e-commerce operations.

For European organizations using the Campcodes Online Shopping Portal 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of customer and transactional data. Exploitation could lead to unauthorized access to personal data protected under GDPR, resulting in legal and financial penalties. Additionally, manipulation of order data can disrupt business operations, damage customer trust, and cause financial losses. Since the vulnerability is remotely exploitable without authentication, attackers can target vulnerable portals from anywhere, increasing the attack surface. The absence of patches means organizations must rely on other mitigations, increasing operational complexity. Retailers and e-commerce businesses in Europe, especially SMEs that may use off-the-shelf solutions like Campcodes, are at heightened risk. The vulnerability could also be leveraged as a foothold for further network intrusion or lateral movement within corporate environments.

1. Immediate mitigation should include restricting access to the /admin/updateorder.php endpoint using network-level controls such as IP whitelisting or VPN access to limit exposure to trusted administrators only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'remark' parameter. 3. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters processed by the updateorder.php script, to prevent injection of malicious SQL code. 4. If possible, apply virtual patching techniques via WAF or reverse proxies until an official patch is released by Campcodes. 5. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 6. Plan and prioritize upgrading or replacing the vulnerable Campcodes Online Shopping Portal 1.0 with a secure, updated version or alternative platform. 7. Educate administrative users on the risks and signs of compromise to enable early detection and response.
