CVE-2025-7832: Church Donation System SQLi Vulnerability

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

bash

# Example: Restrict access to the vulnerable endpoint via .htaccess
# Add to the application's .htaccess file or Apache configuration
<Files "offering.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
