CVE-2025-53529: Wegia Web Manager SQL Injection Flaw

CVE-2025-53529 Overview

CVE-2025-53529 is a critical SQL Injection vulnerability identified in WeGIA, a web-based management platform designed for charitable institutions. The vulnerability exists in the /html/funcionario/profile_funcionario.php endpoint, where the id_funcionario parameter is not properly sanitized or validated before being incorporated into SQL queries. This flaw allows unauthenticated attackers to inject arbitrary SQL commands, potentially leading to complete database compromise, unauthorized data access, and system takeover.

Critical Impact

Unauthenticated attackers can execute arbitrary SQL commands against the database, potentially extracting sensitive donor information, financial records, and administrative credentials from charitable organizations using WeGIA.

Affected Products

• WeGIA versions prior to 3.4.3
• WeGIA web manager for charitable institutions

Technical Details for CVE-2025-53529

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) resides in the employee profile functionality of WeGIA. The vulnerable endpoint at /html/funcionario/profile_funcionario.php accepts user-supplied input through the id_funcionario parameter without implementing proper input validation, sanitization, or parameterized queries. As a result, attackers can craft malicious SQL statements that are directly executed against the backend database.

The vulnerability is particularly severe because it requires no authentication to exploit. An attacker can directly access the vulnerable endpoint and manipulate the id_funcionario parameter to inject SQL commands. This could enable attackers to bypass authentication mechanisms, extract sensitive data from the database including donor information and financial records, modify or delete data, and potentially achieve remote code execution on the underlying server depending on database configuration and privileges.

Root Cause

The root cause of this vulnerability is improper input validation and the use of unsanitized user input in SQL query construction. The id_funcionario parameter is concatenated directly into SQL queries without proper escaping or the use of prepared statements with parameterized queries. This classic SQL Injection pattern allows attackers to break out of the intended query structure and inject their own SQL commands.

Attack Vector

The attack is conducted over the network and requires no user interaction or prior authentication. An attacker can craft HTTP requests to the vulnerable endpoint with malicious SQL payloads in the id_funcionario parameter. Common attack techniques include UNION-based injection to extract data from other tables, Boolean-based blind injection to infer data character by character, and time-based blind injection using database sleep functions to confirm injection success.

The vulnerability can be exploited through direct HTTP requests to the affected endpoint. By manipulating the id_funcionario parameter with SQL injection payloads, attackers can extract database contents, modify records, or potentially execute system commands.

Detection Methods for CVE-2025-53529

Indicators of Compromise

• Unusual SQL error messages in web server logs from the profile_funcionario.php endpoint
• Abnormal database query patterns or high volumes of requests to employee profile endpoints
• Unexpected data exfiltration or database connection attempts from the web application server
• Access log entries showing special characters or SQL keywords in the id_funcionario parameter

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in HTTP request parameters
• Monitor application logs for SQL syntax errors or database exception messages originating from employee profile pages
• Deploy database activity monitoring to detect unauthorized queries or data access patterns
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable verbose logging on the WeGIA application and review logs for injection attempts targeting the id_funcionario parameter
• Configure database audit logging to track all queries executed against sensitive tables
• Set up alerting for failed database query patterns that may indicate reconnaissance or exploitation attempts
• Monitor outbound network traffic from database servers for potential data exfiltration

How to Mitigate CVE-2025-53529

Immediate Actions Required

• Upgrade WeGIA to version 3.4.3 or later immediately to apply the security fix
• If immediate upgrade is not possible, restrict access to the vulnerable endpoint using firewall rules or authentication controls
• Review database logs and application access logs for signs of prior exploitation
• Perform a security audit to identify any data that may have been compromised

Patch Information

The vulnerability has been fixed in WeGIA version 3.4.3. The patch implements proper input validation and parameterized queries for the id_funcionario parameter. The fix can be verified in the GitHub commit 0a061bcc5024937edd18ab3e65ccc8f38deb6957. Organizations should upgrade to the patched version as soon as possible.

Workarounds

• Implement a Web Application Firewall (WAF) with SQL injection detection rules to filter malicious requests
• Restrict network access to the vulnerable endpoint by IP allowlisting or requiring VPN access
• Place the WeGIA application behind an authentication proxy to prevent unauthenticated access to sensitive endpoints
• Temporarily disable or remove the profile_funcionario.php endpoint if not critical to operations until the patch can be applied
