CVE-2025-9694 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Advanced Online Voting System, specifically within the /admin/login.php file. The vulnerability arises from improper sanitization or validation of the 'Username' parameter, allowing an attacker to manipulate the SQL query executed by the backend database. This flaw can be exploited remotely without requiring authentication or user interaction, making it a significant risk. Successful exploitation could enable an attacker to execute arbitrary SQL commands, potentially leading to unauthorized access, data leakage, modification, or deletion of sensitive voting data, and possibly compromising the integrity of the entire voting process. 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. However, the impact on confidentiality, integrity, and availability is rated as low to medium, indicating some limitations in the extent of damage or data exposure. No known public exploits are currently reported, but the vulnerability has been publicly disclosed, increasing the risk of future exploitation. The lack of available patches or mitigations from the vendor further elevates the urgency for organizations using this system to implement protective measures.

For European organizations, especially those involved in electoral processes or civic engagement platforms using the Campcodes Advanced Online Voting System, this vulnerability poses a significant threat to the integrity and trustworthiness of online voting. Exploitation could lead to manipulation or exposure of voter credentials, unauthorized access to administrative functions, and potential alteration or deletion of voting records. Such incidents could undermine public confidence in electoral outcomes and potentially violate data protection regulations such as GDPR if personal data is compromised. Additionally, disruption or manipulation of voting systems could have broader political and social ramifications, particularly in countries with ongoing or upcoming elections. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, including from nation-state actors or cybercriminal groups targeting electoral infrastructure.

Given the absence of official patches, European organizations should immediately implement input validation and sanitization controls at the application and database layers to prevent SQL injection attacks. Employing Web Application Firewalls (WAFs) with specific rules to detect and block SQL injection payloads targeting the /admin/login.php endpoint is critical. Restricting access to the administrative login interface via network segmentation, VPNs, or IP whitelisting can reduce exposure. Regularly monitoring logs for suspicious login attempts or anomalous database queries is essential for early detection. Organizations should also consider deploying database activity monitoring tools to identify and block unauthorized SQL commands. In the medium term, coordinating with the vendor for a security update or migrating to a more secure voting platform is advisable. Conducting security audits and penetration testing focused on injection flaws will help uncover additional vulnerabilities. Finally, educating administrators about the risks and signs of exploitation can improve incident response readiness.
