CVE-2025-30364: Wegia SQL Injection Vulnerability

CVE-2025-30364 Overview

WeGIA is a web-based management system designed for charitable institutions. A critical SQL Injection vulnerability was identified in versions prior to 3.2.8 affecting the endpoint /WeGIA/html/funcionario/remuneracao.php through the id_funcionario parameter. This vulnerability allows attackers to execute arbitrary SQL commands remotely without authentication, potentially compromising the confidentiality, integrity, and availability of all stored data within the application's database.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data, modify database records, or cause complete denial of service to charitable institution management systems.

Affected Products

• WeGIA versions prior to 3.2.8
• WeGIA Web Manager for Charitable Institutions
• Deployments using the /WeGIA/html/funcionario/remuneracao.php endpoint

Technical Details for CVE-2025-30364

Vulnerability Analysis

This SQL Injection vulnerability exists in the employee remuneration module of WeGIA. The id_funcionario parameter in the remuneracao.php endpoint fails to properly sanitize user-supplied input before incorporating it into SQL queries. This classic injection flaw enables attackers to manipulate the structure of database queries, breaking out of the intended parameter context to execute arbitrary SQL statements.

The vulnerability is particularly severe because it requires no authentication or user interaction to exploit. An attacker with network access to the vulnerable endpoint can craft malicious requests that bypass application logic entirely and interact directly with the underlying database. Given that WeGIA manages data for charitable institutions, exploitation could expose sensitive donor information, beneficiary records, financial data, and employee personal details.

Root Cause

The root cause is improper input validation and lack of parameterized queries in the remuneracao.php file. The id_funcionario parameter is directly concatenated into SQL queries without sanitization, prepared statements, or input type validation. This allows special SQL characters and syntax to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack is network-based and can be executed remotely by any attacker who can reach the vulnerable endpoint. The exploitation path involves:

1. Identifying an accessible WeGIA installation running a version prior to 3.2.8
2. Crafting an HTTP request to /WeGIA/html/funcionario/remuneracao.php with a malicious id_funcionario parameter value
3. Injecting SQL syntax to extract data using UNION-based queries, blind injection techniques, or time-based extraction methods
4. Exfiltrating sensitive data or manipulating database records

The vulnerability requires no privileges, no user interaction, and has low attack complexity. Successful exploitation can result in complete database compromise including data theft, unauthorized modifications, and potential denial of service through destructive queries.

Detection Methods for CVE-2025-30364

Indicators of Compromise

• Anomalous HTTP requests to /WeGIA/html/funcionario/remuneracao.php containing SQL syntax characters such as single quotes, UNION statements, or semicolons in the id_funcionario parameter
• Database error messages in application logs indicating SQL syntax errors or unexpected query structures
• Unusual database query patterns including UNION SELECT statements, time-based delay functions, or information_schema queries
• Unexpected data extraction or modification activities in database audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the id_funcionario parameter
• Implement application-level logging to monitor all requests to the remuneracao.php endpoint with parameter values
• Enable database query logging and alert on queries containing SQL injection signatures or accessing system tables
• Utilize intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor network traffic for requests containing encoded SQL injection payloads targeting WeGIA endpoints
• Review database audit logs for unauthorized access attempts or unusual query patterns
• Set up alerts for multiple failed database queries that may indicate injection probing attempts
• Implement real-time monitoring of the remuneracao.php endpoint for suspicious parameter values

How to Mitigate CVE-2025-30364

Immediate Actions Required

• Upgrade WeGIA to version 3.2.8 or later immediately to address this vulnerability
• If immediate patching is not possible, restrict network access to the WeGIA application to trusted IP addresses only
• Implement WAF rules to filter and block requests containing SQL injection patterns to the affected endpoint
• Review database and application logs for signs of prior exploitation attempts

Patch Information

The vulnerability has been fixed in WeGIA version 3.2.8. Organizations should upgrade to this version or later as soon as possible. For detailed information about the security fix, refer to the GitHub Security Advisory (GHSA-x3ff-5qp7-43qv).

Workarounds

• Block external access to the /WeGIA/html/funcionario/remuneracao.php endpoint until patching is complete
• Implement input validation at the web server or reverse proxy level to reject requests with non-numeric id_funcionario values
• Deploy a WAF with SQL injection protection in front of the WeGIA application
• Consider temporarily disabling the affected employee remuneration functionality if business operations permit

# Example: Apache ModSecurity rule to block SQL injection attempts
SecRule ARGS:id_funcionario "!^[0-9]+$" \
    "id:100001,phase:2,deny,status:403,msg:'Potential SQL Injection in id_funcionario'"
