CVE-2025-7830 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Church Donation System, specifically within the /reg.php file. The vulnerability arises from improper sanitization of the 'mobile' parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw can lead to unauthorized access to the backend database, enabling attackers to read, modify, or delete sensitive data related to church donations and donor information. The vulnerability may also affect other parameters, increasing the attack surface. Although the CVSS 4.0 base score is 6.9 (medium severity), the potential impact on confidentiality, integrity, and availability of critical donation system data is significant. The exploit has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild yet. The vulnerability does not require privileges or user interaction, making it easier to exploit remotely over the network. The lack of available patches or mitigations from the vendor further exacerbates the risk for organizations using this software.

For European organizations, especially religious institutions and charities using the Church Donation System 1.0, this vulnerability poses a serious risk. Exploitation could lead to unauthorized disclosure of donor personal and financial information, undermining donor trust and violating data protection regulations such as the GDPR. Data integrity could be compromised, allowing attackers to alter donation records or financial data, potentially causing financial discrepancies and reputational damage. Availability impacts could disrupt donation processing, affecting fundraising operations. Given the sensitivity of donor data and the regulatory environment in Europe, exploitation could result in significant legal and financial consequences. Additionally, the public disclosure of the exploit increases the likelihood of opportunistic attacks targeting vulnerable installations across Europe.

Immediate mitigation steps include implementing web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the /reg.php endpoint and the 'mobile' parameter. Organizations should conduct thorough input validation and sanitization on all user-supplied data, especially parameters involved in database queries. Since no official patch is currently available, organizations should consider isolating or restricting access to the affected system, limiting exposure to the internet or untrusted networks. Monitoring database logs and web server logs for unusual query patterns or errors related to SQL injection attempts is critical for early detection. If feasible, migrating to a more secure or updated donation management system should be planned. Additionally, organizations should review and enhance their incident response plans to address potential data breaches resulting from exploitation of this vulnerability.
