CVE-2025-7830 Overview
A critical SQL injection vulnerability has been identified in code-projects Church Donation System version 1.0. The vulnerability exists in the /reg.php file where the mobile parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to inject malicious SQL statements, potentially leading to unauthorized data access, modification, or deletion within the application's database.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability without authentication to compromise the database, potentially exposing sensitive donor information and financial records.
Affected Products
- Carmelo Church Donation System 1.0
- code-projects Church Donation System (all installations using /reg.php)

Technical Details for CVE-2025-7830
Vulnerability Analysis
This SQL injection vulnerability stems from improper input validation in the registration functionality of Church Donation System. The /reg.php endpoint accepts user-supplied input through the mobile parameter and incorporates it directly into SQL queries without adequate sanitization or parameterization. This allows attackers to manipulate the query structure by injecting SQL syntax through the mobile phone number field.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The network-accessible nature of the vulnerable endpoint means attackers can exploit this remotely without requiring any prior authentication or special privileges. Additional parameters in the registration form may also be susceptible to similar injection attacks.
Root Cause
The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when handling user-supplied data in the /reg.php file. The mobile parameter is concatenated directly into SQL query strings, allowing specially crafted input to escape the intended query context and execute arbitrary SQL commands. This represents a fundamental secure coding oversight in the application's database interaction layer.
Attack Vector
The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /reg.php endpoint, embedding SQL injection payloads within the mobile parameter. The exploitation is straightforward due to the low attack complexity and can be automated using common SQL injection tools.
The vulnerability has been publicly disclosed, and technical details are available through the GitHub Issue Tracker and VulDB. Attackers could leverage standard SQL injection techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection to extract database contents, bypass authentication mechanisms, or modify stored data.
Detection Methods for CVE-2025-7830
Indicators of Compromise
- Unusual or malformed values in the mobile parameter of requests to /reg.php containing SQL syntax characters (single quotes, double dashes, UNION keywords)
- Database error messages appearing in HTTP responses from the registration endpoint
- Unexpected database queries in database logs showing injection patterns
- Anomalous spikes in requests to the /reg.php endpoint from single IP addresses
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block common SQL injection patterns in POST/GET parameters
- Monitor application logs for requests containing SQL keywords (SELECT, UNION, INSERT, UPDATE, DELETE) in form fields
- Deploy database activity monitoring to identify queries with unusual structures or unauthorized data access patterns
- Utilize intrusion detection systems configured with SQL injection signature rules
Monitoring Recommendations
- Enable verbose logging on the web server for all requests to /reg.php and similar form-processing endpoints
- Configure database audit logging to track all queries executed against sensitive tables
- Set up alerts for failed database queries that may indicate injection attempts
- Monitor for data exfiltration patterns such as large query result sets or unusual outbound data transfers
How to Mitigate CVE-2025-7830
Immediate Actions Required
- Remove or disable the /reg.php file from production environments until a patch is available
- Implement a web application firewall with SQL injection detection rules as an interim protective measure
- Restrict network access to the vulnerable application to trusted IP ranges only
- Review database logs for any evidence of prior exploitation and assess potential data compromise
- Backup all database content before implementing any changes
Patch Information
As of the last modification date, no official vendor patch has been released for this vulnerability. Organizations using Church Donation System should contact the developer through Code Projects for remediation guidance. In the absence of an official patch, implementing the workarounds below is strongly recommended.
For additional technical details and vulnerability tracking, refer to VulDB entry #316934.
Workarounds
- Rewrite the vulnerable code to use parameterized queries or prepared statements for all database interactions
- Implement server-side input validation to restrict the mobile parameter to numeric characters only
- Deploy a reverse proxy or WAF to filter malicious requests before they reach the application
- Consider replacing the vulnerable application with a more secure donation management solution
# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule ARGS:mobile "@rx (?i)(union|select|insert|update|delete|drop|truncate|exec|--|')" \
"id:100001,phase:2,deny,status:403,log,msg:'SQL Injection attempt blocked in mobile parameter'"
