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 can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands against the backend database without requiring any user interaction or privileges. The vulnerability potentially affects other parameters as well, indicating a broader input validation weakness in the application. Exploiting this flaw could lead to unauthorized data access, data modification, or even full compromise of the database server. Although no known exploits are currently observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The CVSS 4.0 base score is 6.9, reflecting medium severity, with network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. However, given the critical nature of SQL injection vulnerabilities and the potential for data breaches, this vulnerability demands prompt attention.

For European organizations using the Church Donation System 1.0, this vulnerability poses significant risks. The system likely manages sensitive donor information, including personal and financial data, which if compromised, could lead to privacy violations under GDPR regulations. Unauthorized access or modification of donation records could disrupt financial reporting and damage organizational reputation. Additionally, attackers could leverage the SQL injection to pivot into the internal network or deploy further attacks, potentially impacting availability of donation services. The public disclosure of the vulnerability increases the likelihood of exploitation attempts, especially targeting religious or charitable organizations in Europe that rely on this software. The impact extends beyond data confidentiality to include integrity and availability of critical donation processing functions, potentially affecting fundraising operations and stakeholder trust.

Immediate mitigation should include applying any available patches or updates from the vendor; however, no patch links are currently provided. In the absence of official patches, organizations should implement web application firewall (WAF) rules to detect and block SQL injection attempts targeting the /reg.php endpoint, especially focusing on the 'mobile' parameter. Input validation and sanitization should be enforced at the application level, employing parameterized queries or prepared statements to prevent injection. Conduct thorough code reviews and security testing of all input parameters beyond 'mobile' to identify and remediate similar vulnerabilities. Organizations should also monitor logs for suspicious database queries or unusual access patterns. Segmentation of the database server and limiting database user privileges can reduce the impact of a successful injection. Finally, organizations should prepare incident response plans to quickly address any exploitation attempts.
