CVE-2025-26608: Wegia Web Manager SQL Injection Flaw

CVE-2025-26608 Overview

CVE-2025-26608 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 dependente_docdependente.php endpoint and allows attackers to execute arbitrary SQL queries, potentially leading to unauthorized access to sensitive information stored in the application's database.

Critical Impact

This SQL Injection vulnerability enables unauthenticated remote attackers to execute arbitrary SQL commands against the WeGIA database, potentially compromising all stored institutional data, user credentials, and sensitive information.

Affected Products

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

Technical Details for CVE-2025-26608

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) is located in the dependente_docdependente.php endpoint of the WeGIA application. The vulnerability arises from improper neutralization of special characters used in SQL commands, allowing user-supplied input to be directly incorporated into database queries without adequate sanitization or parameterization.

The attack can be conducted remotely over the network without requiring any authentication or user interaction. Successful exploitation grants attackers the ability to read, modify, or delete data from the database, potentially compromising the confidentiality, integrity, and availability of the entire system and any connected systems.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries in the dependente_docdependente.php endpoint. User-controlled input is concatenated directly into SQL statements, enabling attackers to inject malicious SQL syntax that alters the intended query logic. This is a classic SQL Injection pattern where dynamic SQL construction without proper escaping or prepared statements creates an exploitable condition.

Attack Vector

The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely by sending specially crafted HTTP requests to the vulnerable endpoint. The attacker does not need any privileges or authentication to execute the attack, and no user interaction is required.

An attacker would craft malicious input containing SQL metacharacters and commands, targeting the dependente_docdependente.php endpoint. When the application processes this input without proper sanitization, the injected SQL code executes against the backend database with the same privileges as the application's database connection.

Detection Methods for CVE-2025-26608

Indicators of Compromise

• Unusual database queries originating from the dependente_docdependente.php endpoint
• HTTP requests to dependente_docdependente.php containing SQL metacharacters such as single quotes, double dashes, UNION keywords, or semicolons
• Database error messages appearing in application logs indicating malformed queries
• Unexpected data exfiltration or database access patterns from the web application

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting WeGIA endpoints
• Monitor HTTP request logs for suspicious parameters containing SQL syntax directed at dependente_docdependente.php
• Deploy database activity monitoring to identify anomalous queries or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for common SQL Injection attack patterns

Monitoring Recommendations

• Enable detailed logging on the WeGIA application to capture all requests to the dependente_docdependente.php endpoint
• Configure database audit logging to track queries executed by the application database user
• Set up alerts for database errors that may indicate attempted SQL Injection attacks
• Regularly review web server access logs for patterns consistent with automated SQL Injection scanning tools

How to Mitigate CVE-2025-26608

Immediate Actions Required

• Upgrade WeGIA to version 3.2.13 or later immediately
• If immediate patching is not possible, restrict network access to the WeGIA application
• Implement WAF rules to filter SQL Injection attempts targeting the vulnerable endpoint
• Review database logs for signs of prior exploitation and assess potential data compromise

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. The patch information and security advisory are available through the WeGIA GitHub Security Advisory.

Workarounds

• There are no known workarounds for this vulnerability according to the vendor advisory
• Organizations unable to patch immediately should consider taking the application offline or restricting access to trusted networks only
• Deploy a WAF in front of the application as a temporary defensive measure, though this is not a complete mitigation
• Implement network segmentation to limit the blast radius if the vulnerability is exploited

# Upgrade WeGIA to patched version
cd /path/to/wegia
git fetch --tags
git checkout v3.2.13
# Follow standard upgrade procedures for your installation
