CVE-2025-26611: Wegia Wegia SQL Injection Vulnerability

CVE-2025-26611 Overview

A critical SQL Injection vulnerability has been identified in WeGIA, an open source Web Manager for Institutions with a focus on Portuguese language users. The vulnerability exists in the remover_produto.php endpoint and allows attackers to execute arbitrary SQL queries, potentially leading to unauthorized access to sensitive information, data manipulation, and complete database compromise.

Critical Impact

This SQL Injection vulnerability enables unauthenticated remote attackers to execute arbitrary SQL commands against the backend database, potentially exposing sensitive institutional data, user credentials, and enabling full database takeover.

Affected Products

• WeGIA Web Manager versions prior to 3.2.13
• WeGIA installations using the vulnerable remover_produto.php endpoint
• All WeGIA deployments with network-accessible interfaces

Technical Details for CVE-2025-26611

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) resides in the remover_produto.php endpoint of the WeGIA application. The endpoint fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating a classic injection point that attackers can exploit to manipulate database operations.

The vulnerability is particularly severe due to its network-accessible attack vector, requiring no authentication or user interaction to exploit. An attacker can craft malicious SQL statements that are executed directly against the database backend, bypassing application-level access controls entirely.

Successful exploitation could allow attackers to extract sensitive data from the database, modify or delete existing records, escalate privileges within the application, or potentially achieve remote code execution depending on the database configuration and privileges.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries in the remover_produto.php endpoint. User-supplied input is directly concatenated into SQL query strings without proper sanitization or the use of prepared statements, allowing attackers to inject malicious SQL syntax that alters the intended query logic.

Attack Vector

The attack vector is network-based, targeting the remover_produto.php endpoint. An attacker can send specially crafted HTTP requests containing SQL injection payloads to manipulate database queries. Since the vulnerability requires no authentication or user interaction, any network attacker with access to the WeGIA application can exploit it.

The exploitation typically involves injecting SQL commands through vulnerable parameters, using techniques such as UNION-based injection to extract data, boolean-based blind injection to infer database contents, or time-based blind injection when other methods are not feasible. The complete lack of input sanitization means that standard SQL injection payloads are likely to succeed without requiring advanced bypass techniques.

Detection Methods for CVE-2025-26611

Indicators of Compromise

• Unusual or malformed requests to the remover_produto.php endpoint containing SQL syntax characters (single quotes, semicolons, UNION statements)
• Database error messages in application logs indicating SQL syntax errors from unexpected input
• Unexplained database queries or data access patterns in database audit logs
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to remover_produto.php
• Monitor application logs for requests containing common SQL injection signatures such as ' OR 1=1, UNION SELECT, or -- comment sequences
• Enable database query logging and alert on queries with suspicious patterns or unexpected syntax
• Deploy Intrusion Detection Systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Establish baseline metrics for normal traffic to the remover_produto.php endpoint and alert on anomalies
• Configure real-time alerting for multiple failed or error-generating requests to the vulnerable endpoint
• Implement database activity monitoring to detect unauthorized data access or schema enumeration attempts

How to Mitigate CVE-2025-26611

Immediate Actions Required

• Upgrade WeGIA to version 3.2.13 or later immediately to address this vulnerability
• If immediate patching is not possible, consider temporarily disabling access to the remover_produto.php endpoint
• Review database logs for evidence of exploitation attempts and take appropriate incident response actions if compromise is detected
• Implement network-level access controls to restrict access to the WeGIA application to trusted networks only

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 security advisory is available through the GitHub Security Advisory (GHSA-q273-4vcj-qqp4) for additional details.

Workarounds

• There are no known workarounds for this vulnerability according to the vendor advisory
• As a temporary measure, restrict network access to the WeGIA application using firewall rules
• Consider placing a Web Application Firewall (WAF) in front of the application with SQL injection protection enabled
• Disable or restrict access to the remover_produto.php endpoint until patching is complete

# Example: Restrict access to WeGIA using iptables (temporary mitigation)
# Only allow access from trusted admin network
iptables -A INPUT -p tcp --dport 80 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP

# Example: Apache configuration to disable vulnerable endpoint
# Add to .htaccess or Apache configuration
<Files "remover_produto.php">
    Require all denied
</Files>
