CVE-2025-8924 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Water Billing System. The vulnerability arises from improper sanitization or validation of the 'ID' parameter in the /viewbill.php endpoint. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This could lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability requires no authentication or user interaction, making it exploitable remotely by any attacker aware of the flaw. 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 allow significant data exposure or manipulation. No patches or fixes have been publicly released yet, and while no known exploits are currently observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a specialized water billing system likely deployed by municipal or regional water utilities to manage customer billing and usage data.

For European organizations, particularly municipal water utilities or regional water service providers using Campcodes Online Water Billing System 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive customer billing information, including personal data and consumption records, potentially violating GDPR requirements for data protection and privacy. Attackers could manipulate billing data, causing financial losses or service disruptions. Additionally, unauthorized database access could be leveraged as a foothold for further network intrusion, potentially impacting broader IT infrastructure. The public disclosure and remote exploitability increase the urgency for European entities to assess their exposure. Given the critical nature of water utilities as essential services, any disruption or data breach could have reputational, regulatory, and operational consequences.

Organizations should immediately identify any deployments of Campcodes Online Water Billing System version 1.0 within their infrastructure. Since no official patches are currently available, mitigations include: 1) Implementing Web Application Firewall (WAF) rules specifically targeting SQL injection patterns on the /viewbill.php endpoint and the 'ID' parameter to block malicious payloads. 2) Applying input validation and parameterized queries or prepared statements if source code access is available, to sanitize the 'ID' parameter properly. 3) Restricting access to the billing system interface to trusted IP ranges or via VPN to reduce exposure. 4) Monitoring logs for unusual query patterns or repeated failed attempts indicative of SQL injection attempts. 5) Planning for an urgent upgrade or replacement of the vulnerable system once a vendor patch or newer secure version is released. 6) Conducting a thorough security audit of related systems to detect any signs of compromise. These steps go beyond generic advice by focusing on immediate protective controls and compensating measures until a patch is available.
