CVE-2025-46828: Wegia Wegia SQL Injection Vulnerability

CVE-2025-46828 Overview

WeGIA is a web manager for charitable institutions. An unauthenticated SQL Injection vulnerability was identified in versions up to and including 3.3.0 in the endpoint /html/socio/sistema/get_socios.php, specifically in the query parameter. This issue allows attackers to inject and execute arbitrary SQL statements against the application's underlying database. As a result, it may lead to data exfiltration, authentication bypass, or complete database compromise. Version 3.3.1 fixes the issue.

Critical Impact

This unauthenticated SQL Injection vulnerability allows remote attackers to completely compromise the database without any credentials, potentially exposing sensitive donor and beneficiary data managed by charitable institutions.

Affected Products

• WeGIA versions up to and including 3.3.0
• Endpoint: /html/socio/sistema/get_socios.php
• Component: wegia:wegia

Technical Details for CVE-2025-46828

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists in the /html/socio/sistema/get_socios.php endpoint of WeGIA, a web management system used by charitable institutions. The vulnerability is particularly severe because it requires no authentication to exploit, allowing any network-based attacker to interact directly with the backend database.

The vulnerable endpoint accepts user-supplied input through the query parameter and passes it directly to mysqli_query() without any sanitization or parameterized queries. This classic SQL Injection pattern enables attackers to execute arbitrary SQL commands, potentially leading to unauthorized access to sensitive charitable organization data, including donor information, beneficiary records, and financial transactions.

Root Cause

The root cause is the direct use of user-controlled input in SQL queries without proper input validation or parameterized statements. The PHP code directly concatenates the $_POST['query'] parameter into the database query, creating a textbook SQL Injection vulnerability. The lack of input sanitization allows malicious SQL syntax to be interpreted and executed by the database engine.

Attack Vector

The attack is network-based and can be executed by any unauthenticated remote attacker. The attacker sends a crafted HTTP POST request to the vulnerable endpoint with malicious SQL statements in the query parameter. Since no authentication is required, the attack surface is significant for any internet-exposed WeGIA installation. Successful exploitation can lead to:

• Complete database exfiltration
• Authentication bypass to gain administrative access
• Data modification or deletion
• Potential lateral movement if database credentials are reused

// Vulnerable code pattern from get_socios.php
<?php
+/*Analisar futura remoção
     require("../conexao.php");
     $query = $_POST['query'];
     $resultado = mysqli_query($conexao, $query);

Source: GitHub Commit Update

The patch comment "Analisar futura remoção" (analyze future removal) suggests the developers are considering removing or refactoring this vulnerable endpoint entirely.

Detection Methods for CVE-2025-46828

Indicators of Compromise

• Unusual HTTP POST requests to /html/socio/sistema/get_socios.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or DROP
• Web server logs showing repeated requests to the vulnerable endpoint with encoded or obfuscated payloads
• Database logs indicating unexpected queries, error messages, or data access patterns
• Evidence of data exfiltration through timing-based or error-based SQL injection techniques

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /html/socio/sistema/get_socios.php endpoint
• Monitor HTTP request logs for POST requests containing SQL metacharacters (single quotes, semicolons, comment sequences)
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging on the WeGIA web application and database server
• Set up alerts for failed database queries or SQL syntax errors that may indicate injection attempts
• Monitor for large data transfers from the database that could indicate successful exfiltration
• Review authentication logs for bypass attempts following potential SQL injection activity

How to Mitigate CVE-2025-46828

Immediate Actions Required

• Upgrade WeGIA to version 3.3.1 or later immediately to remediate this vulnerability
• If immediate patching is not possible, restrict network access to the WeGIA application to trusted IP ranges only
• Implement WAF rules to block SQL injection attempts targeting the vulnerable endpoint
• Review database logs for signs of prior exploitation and assess potential data exposure

Patch Information

WeGIA version 3.3.1 addresses this SQL Injection vulnerability. Organizations should upgrade immediately by obtaining the patched version from the official WeGIA repository. The security fix is documented in the GitHub Security Advisory GHSA-5qw5-q55h-6qg7 and the corresponding commit 214dab59509bd3637f94adf381298c12da4ff80f.

Workarounds

• Block access to the /html/socio/sistema/get_socios.php endpoint at the web server or firewall level until patching is complete
• Implement strict input validation using a WAF to filter SQL injection payloads
• Restrict database user permissions to limit the impact of potential SQL injection attacks
• Consider temporarily disabling the affected functionality if it is not business-critical
