CVE-2025-7930: Church Donation System SQLi Vulnerability

CVE-2025-7930 Overview

A critical SQL injection vulnerability has been identified in code-projects Church Donation System version 1.0. The vulnerability exists in the /members/add_members.php file, where improper handling of the mobile parameter allows attackers to inject malicious SQL statements. This flaw enables remote exploitation without authentication, potentially compromising the integrity and confidentiality of the donation management database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive donor information, modify database records, or potentially gain further access to the underlying system through database manipulation techniques.

Technical Details for CVE-2025-7930

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs due to insufficient input validation in the member registration functionality. The application fails to properly sanitize user-supplied data in the mobile parameter before incorporating it into SQL queries. This allows attackers to break out of the intended query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is remotely exploitable without any authentication requirements, making it accessible to any network-based attacker. The impact includes potential unauthorized read access to sensitive donor information, modification of donation records, and deletion of data. According to the advisory, other parameters in the same functionality may also be vulnerable to similar injection attacks.

Root Cause

The root cause of this vulnerability lies in the direct use of user input in SQL query construction without proper parameterization or input sanitization. The add_members.php script accepts the mobile parameter and concatenates it directly into SQL statements, allowing special SQL characters and commands to be interpreted by the database engine rather than treated as literal data values.

Attack Vector

The attack is conducted remotely over the network against the web application interface. An attacker can submit specially crafted input containing SQL metacharacters and statements to the mobile parameter in requests to /members/add_members.php. Since no authentication is required, any remote attacker with network access to the application can exploit this vulnerability.

The exploitation technique involves injecting SQL syntax that alters the logic of the backend query. Common techniques include using single quotes to escape string contexts, UNION-based injection to extract data from other tables, or time-based blind injection to infer database contents when direct output is not available. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Detection Methods for CVE-2025-7930

Indicators of Compromise

• HTTP POST requests to /members/add_members.php containing SQL injection patterns such as single quotes, UNION SELECT statements, or SQL comment sequences in the mobile parameter
• Database error messages in application logs indicating malformed SQL queries or syntax errors
• Unusual database queries in database server logs, particularly SELECT statements with UNION clauses or time-based functions like SLEEP() or BENCHMARK()
• Unexpected data exfiltration or modifications to the church donation database tables

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP request parameters
• Enable detailed logging on the database server to capture all queries executed against the donation system database
• Implement intrusion detection system (IDS) signatures for common SQL injection attack patterns targeting the affected endpoint
• Monitor for anomalous access patterns to the /members/add_members.php endpoint, including high request volumes or requests from unusual geographic locations

Monitoring Recommendations

• Configure alerts for database errors or exceptions that may indicate injection attempts
• Monitor application server logs for requests containing SQL metacharacters or keywords like UNION, SELECT, INSERT, DELETE, or DROP
• Review database query performance for unexpected long-running queries that may indicate time-based blind injection attacks
• Implement real-time monitoring of database table modifications to detect unauthorized data changes

How to Mitigate CVE-2025-7930

Immediate Actions Required

• Take the Church Donation System offline or restrict network access until a patch or workaround can be applied
• Review database logs for evidence of prior exploitation and assess whether sensitive data may have been compromised
• Implement web application firewall rules to block requests containing SQL injection patterns to the /members/add_members.php endpoint
• Audit all database accounts used by the application and ensure they follow least privilege principles

Patch Information

No official vendor patch is currently available for this vulnerability. Organizations using Church Donation System 1.0 should monitor the Code Projects Resource Hub for security updates. Additional technical details about this vulnerability can be found in the GitHub Issue Discussion and VulDB #317059.

Workarounds

• Implement input validation to reject mobile parameter values containing SQL metacharacters such as single quotes, double dashes, or semicolons
• Modify the application code to use prepared statements or parameterized queries instead of string concatenation for database operations
• Deploy a web application firewall in front of the application with SQL injection protection enabled
• Restrict database user permissions to the minimum required operations, removing DELETE and DROP privileges where possible

# Example: Apache mod_rewrite rule to block SQL injection patterns
# Add to .htaccess in the web application root
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|delete|drop|update|;|'|--) [NC]
RewriteRule ^members/add_members\.php$ - [F,L]
