CVE-2025-7859 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Church Donation System, specifically within the /members/update_password_admin.php file. The vulnerability arises due to improper sanitization or validation of the 'new_password' parameter, which is directly used in SQL queries without adequate protection. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. The attack vector requires no authentication or user interaction, making it highly accessible to attackers. Exploiting this vulnerability could lead to unauthorized data access, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. Although the CVSS 4.0 score is 6.9 (medium severity), the lack of authentication and remote exploitability elevate the risk. No patches or fixes have been published yet, and while no known exploits are currently in the wild, public disclosure increases the likelihood of exploitation attempts. The vulnerability impacts the core functionality of the donation system, which is critical for managing sensitive donor information and financial transactions.

For European organizations using the Church Donation System 1.0, this vulnerability poses significant risks. Churches and religious organizations often handle sensitive personal and financial data of donors, including payment details and contact information. Exploitation could lead to data breaches exposing donor identities and financial contributions, damaging trust and potentially violating GDPR and other data protection regulations. Additionally, attackers could manipulate donation records or disrupt system availability, impacting fundraising operations. Given the critical role these systems play in community support and charitable activities, any compromise could have reputational and operational consequences. The remote, unauthenticated nature of the vulnerability means attackers can exploit it without insider access, increasing the threat level. European organizations may face legal and compliance repercussions if donor data is exposed or mishandled due to this vulnerability.

Immediate mitigation should focus on implementing proper input validation and parameterized queries or prepared statements to prevent SQL injection in the update_password_admin.php script. Organizations should conduct a thorough code review of all input handling related to authentication and password management. Until a vendor patch is available, deploying a Web Application Firewall (WAF) with custom rules to detect and block SQL injection patterns targeting the 'new_password' parameter can reduce exposure. Monitoring logs for suspicious database queries or repeated failed attempts to update passwords can help detect exploitation attempts early. Restricting access to the administration interface by IP whitelisting or VPN can add an additional layer of defense. Organizations should also prepare an incident response plan specific to potential data breaches involving donor information. Finally, applying strict database user permissions to limit the impact of any successful injection is recommended.
