CVE-2025-7831 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Church Donation System, specifically within the /members/Tithes.php file. The vulnerability arises due to improper sanitization or validation of the 'trcode' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without any authentication or user interaction, by injecting crafted SQL commands through the 'trcode' parameter. This can lead to unauthorized access to the backend database, allowing attackers to read, modify, or delete sensitive data related to church donations and member information. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild yet. The CVSS 4.0 base score is 6.9, indicating a medium severity level, reflecting the ease of remote exploitation without privileges but with limited impact on confidentiality, integrity, and availability. The vulnerability does not require user interaction, and the attack vector is network-based, making it accessible to remote attackers. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls.

For European organizations using the Church Donation System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of donor and financial data. Exploitation could lead to unauthorized disclosure of sensitive personal and financial information, potentially violating GDPR and other data protection regulations, resulting in legal and reputational consequences. Integrity of donation records could be compromised, affecting financial reporting and trustworthiness. Availability impact is limited but could occur if attackers execute destructive SQL commands. Given the system's role in managing donations, disruption could affect operational continuity of religious and charitable organizations. The public disclosure of the vulnerability increases the likelihood of targeted attacks, especially against organizations with limited cybersecurity resources. European entities must consider the regulatory implications and the potential for financial fraud or data breaches stemming from this vulnerability.

Since no official patches are currently available, European organizations should immediately implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'trcode' parameter. 2) Conduct thorough input validation and sanitization on all user-supplied data, particularly the 'trcode' parameter, using parameterized queries or prepared statements if possible within the application code. 3) Restrict database user permissions to the minimum necessary, preventing unauthorized data manipulation or extraction. 4) Monitor application logs and database queries for suspicious activity indicative of SQL injection attempts. 5) Isolate the Church Donation System within a segmented network zone to limit lateral movement in case of compromise. 6) Plan and prioritize upgrading or replacing the vulnerable system with a patched or more secure alternative. 7) Educate IT staff and administrators on the vulnerability and signs of exploitation to enable rapid incident response.
