CVE-2025-26612: Wegia Web Manager SQLi Vulnerability

CVE-2025-26612 Overview

CVE-2025-26612 is a critical SQL Injection vulnerability discovered in WeGIA, an open source Web Manager for Institutions with a focus on Portuguese language users. The vulnerability exists in the adicionar_almoxarife.php endpoint and could allow an attacker to execute arbitrary SQL queries, enabling unauthorized access to sensitive information stored in the application's database.

Critical Impact

This SQL Injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL queries against the WeGIA database, potentially leading to complete data breach, data manipulation, and unauthorized system access.

Affected Products

• WeGIA versions prior to 3.2.13
• WeGIA Web Manager installations using vulnerable adicionar_almoxarife.php endpoint

Technical Details for CVE-2025-26612

Vulnerability Analysis

This vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The vulnerable endpoint adicionar_almoxarife.php fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to inject malicious SQL statements that are then executed by the database server with the same privileges as the application.

The network-accessible nature of this vulnerability means that any attacker with network access to the WeGIA application can potentially exploit it without requiring any prior authentication or user interaction. The impact extends beyond the immediate application, as successful exploitation could affect connected systems and allow access to the entire database contents.

Root Cause

The root cause of this vulnerability lies in the improper handling of user input within the adicionar_almoxarife.php endpoint. The application fails to implement proper input validation and parameterized queries, allowing user-controlled data to be directly concatenated into SQL statements. This fundamental coding flaw enables attackers to manipulate the structure and logic of database queries.

Attack Vector

The attack vector is network-based, requiring no authentication or special privileges. An attacker can craft malicious HTTP requests to the adicionar_almoxarife.php endpoint containing SQL injection payloads. These payloads, when processed by the vulnerable endpoint, are executed against the database server, allowing the attacker to:

• Extract sensitive data from the database
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially execute commands on the underlying database server

The vulnerability can be exploited through standard HTTP requests, making it accessible to any attacker who can reach the WeGIA application over the network. For detailed technical information about the vulnerability, refer to the GitHub Security Advisory.

Detection Methods for CVE-2025-26612

Indicators of Compromise

• Anomalous SQL error messages in application or web server logs originating from adicionar_almoxarife.php
• Unusual database query patterns or execution times from the WeGIA application
• Evidence of data exfiltration or unauthorized database access in audit logs
• HTTP requests to adicionar_almoxarife.php containing SQL syntax characters such as single quotes, semicolons, or UNION statements

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block SQL injection patterns targeting the adicionar_almoxarife.php endpoint
• Implement database activity monitoring to identify anomalous queries or unauthorized data access
• Enable detailed logging on the WeGIA application to capture request parameters and SQL query execution
• Use intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for suspicious requests to adicionar_almoxarife.php with encoded or malicious payloads
• Set up alerts for database errors or exceptions that may indicate injection attempts
• Review database audit logs regularly for unauthorized data access or schema modifications
• Implement real-time monitoring of outbound network traffic for potential data exfiltration

How to Mitigate CVE-2025-26612

Immediate Actions Required

• Upgrade WeGIA to version 3.2.13 or later immediately
• Restrict network access to the WeGIA application to trusted sources only
• Deploy a web application firewall (WAF) with SQL injection protection rules
• Review database permissions to ensure the application uses least-privilege access

Patch Information

The vulnerability has been addressed in WeGIA version 3.2.13. All users are strongly advised to upgrade to this version or later to remediate the vulnerability. The patch is available through the official WeGIA repository. For additional details, see the GitHub Security Advisory GHSA-9cwj-p4x6-pp88.

Workarounds

• There are no known workarounds for this vulnerability according to the vendor advisory
• As a temporary measure, consider restricting access to the adicionar_almoxarife.php endpoint via web server configuration until patching is complete
• Implement network-level access controls to limit exposure of the vulnerable endpoint

# Example: Restrict access to vulnerable endpoint via Apache .htaccess (temporary measure only)
# Place in the WeGIA web root directory
<Files "adicionar_almoxarife.php">
    Require ip 192.168.1.0/24
    # Replace with your trusted IP range
</Files>
