CVE-2025-7832 Overview
A critical SQL injection vulnerability has been identified in the Carmelo Church Donation System version 1.0. This vulnerability exists in the file /members/offering.php where the trcode parameter is improperly handled, allowing attackers to inject malicious SQL queries. The attack can be initiated remotely over the network without requiring authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or system compromise.
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-level attacks.

Technical Details for CVE-2025-7832
Vulnerability Analysis
This SQL injection vulnerability stems from inadequate input validation in the /members/offering.php endpoint. The trcode parameter accepts user-supplied input that is directly incorporated into SQL queries without proper sanitization or parameterization. This classic injection flaw allows attackers to manipulate the query logic, potentially bypassing authentication mechanisms, extracting data from the database, or executing administrative database operations.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection vulnerabilities where user input is improperly incorporated into commands or queries.
Root Cause
The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when handling the trcode parameter in the offering.php file. User-controlled input is concatenated directly into SQL query strings, allowing special SQL characters and commands to alter the intended query structure.
Attack Vector
The vulnerability is exploitable remotely over the network. An attacker can craft malicious HTTP requests to the /members/offering.php endpoint, injecting SQL commands through the trcode parameter. No authentication or user interaction is required to exploit this vulnerability, making it accessible to any network-connected attacker who can reach the application.
The exploitation technique involves injecting SQL syntax into the trcode parameter to modify the query's behavior. Common attack patterns include:
- Using single quotes and SQL keywords to break out of the original query context
- Appending UNION SELECT statements to exfiltrate data from other tables
- Injecting time-based blind SQL injection payloads for data extraction when direct output is not available
- Using database-specific functions to enumerate schema information
Technical details and proof-of-concept information have been discussed on GitHub and documented in VulDB Entry #316936.
Detection Methods for CVE-2025-7832
Indicators of Compromise
- Unusual or malformed requests to /members/offering.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
- Database error messages in application logs indicating SQL syntax errors
- Unexpected queries or data access patterns in database audit logs
- Evidence of data exfiltration or unauthorized database modifications
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the trcode parameter
- Implement input validation logging to capture suspicious parameter values before they reach the database layer
- Enable database query logging and monitor for anomalous query patterns or syntax errors
- Configure intrusion detection systems to alert on SQL injection attack signatures in HTTP traffic
Monitoring Recommendations
- Monitor web server access logs for requests to /members/offering.php with encoded or suspicious trcode parameter values
- Set up alerts for database errors originating from the Church Donation System application
- Review database audit logs regularly for unauthorized data access or schema enumeration attempts
- Implement real-time monitoring of application-level authentication and authorization events
How to Mitigate CVE-2025-7832
Immediate Actions Required
- Restrict network access to the Church Donation System to trusted IP addresses only until patches are applied
- Implement a Web Application Firewall with SQL injection detection rules as an interim protective measure
- Review database user permissions and apply principle of least privilege to limit potential damage from exploitation
- Back up all database contents to enable recovery in case of data compromise
Patch Information
No official vendor patch has been released at the time of this analysis. Organizations should monitor Code Projects for security updates. Given that this is a code-projects.org application, users may need to implement manual code fixes or consider alternative solutions.
Workarounds
- Modify the /members/offering.php file to use parameterized queries (prepared statements) instead of string concatenation for SQL queries
- Implement strict input validation on the trcode parameter, allowing only expected alphanumeric characters
- Deploy network-level access controls to restrict access to the application from untrusted networks
- Consider disabling the offering functionality temporarily if it is not critical to operations
# Example: Restrict access to the vulnerable endpoint via .htaccess
# Add to the application's .htaccess file or Apache configuration
