CVE-2025-7928 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Church Donation System, specifically within the /members/edit_user.php file. The vulnerability arises from improper sanitization or validation of the 'firstname' parameter, allowing an attacker to inject malicious SQL code remotely without any authentication or user interaction. This injection flaw can potentially be exploited to manipulate backend database queries, leading to unauthorized data access, data modification, or even complete compromise of the database. Although the exact extent of affected parameters beyond 'firstname' is unknown, the presence of multiple vulnerable inputs could exacerbate the impact. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. The exploit has been publicly disclosed but there are no confirmed reports of active exploitation in the wild. The lack of available patches or vendor advisories increases the risk for organizations still running this software version. Given the nature of SQL Injection, attackers could leverage this flaw to extract sensitive donor information, alter donation records, or disrupt the system's operation, which is critical for organizations relying on this system for fundraising and donor management.

For European organizations using the Church Donation System 1.0, this vulnerability poses significant risks to the confidentiality and integrity of sensitive donor data, including personal identification and financial contributions. Exploitation could lead to unauthorized disclosure of donor identities, financial fraud, or manipulation of donation records, undermining trust and potentially violating GDPR regulations concerning personal data protection. Additionally, disruption of donation processing could impact the operational availability of fundraising activities, affecting revenue streams for religious and charitable organizations. The reputational damage from a data breach or service disruption could be severe, especially for organizations with high public visibility or those subject to strict compliance requirements. Given the remote and unauthenticated nature of the exploit, attackers could target multiple organizations indiscriminately, increasing the threat landscape across Europe.

European organizations should immediately assess their exposure to the Church Donation System 1.0 and prioritize upgrading to a patched or newer version once available. In the absence of an official patch, organizations should implement web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'firstname' parameter and other input fields. Input validation and parameterized queries should be enforced at the application level to prevent injection. Conduct thorough code reviews and penetration testing focused on all user input handling in the /members/edit_user.php module. Organizations should also monitor logs for suspicious database query patterns or anomalous access attempts. Segmentation of the database and limiting database user privileges can reduce the impact of a successful injection. Finally, ensure that backups are current and tested to enable recovery in case of data corruption or loss.
