CVE-2025-26607

Remediation/Mitigation Strategy for CVE-2025-26607: WeGIA SQL Injection Vulnerability

This document outlines the vulnerability, its severity, known exploitation details, and the recommended remediation and mitigation strategies for CVE-2025-26607, a SQL Injection vulnerability in the WeGIA web application.

1. Vulnerability Description

  • Vulnerability: SQL Injection
  • Affected Software: WeGIA (Web Manager for Institutions)
  • Affected Endpoint: documento_excluir.php
  • Description: The documento_excluir.php endpoint in WeGIA is vulnerable to SQL injection. This allows an attacker to inject malicious SQL code into database queries, potentially gaining unauthorized access to sensitive information, modifying data, or even executing arbitrary commands on the database server.

2. Severity

  • CVSS Score: 10.0 (Critical) - Based on the provided data. This score signifies the highest level of risk.
  • Impact: The SQL injection vulnerability can lead to:
    • Data Breach: Exposure of sensitive information, including user credentials, student records, financial data, and other confidential institutional data.
    • Data Manipulation: Modification or deletion of data, potentially causing significant disruption to institutional operations and data integrity.
    • Account Takeover: Compromise of user accounts, including administrator accounts, allowing attackers to gain full control of the WeGIA application.
    • System Compromise: In severe cases, the attacker may be able to execute arbitrary commands on the database server, potentially leading to a full system compromise.

3. Known Exploitation

  • Exploitability: Exploitable over the network. No specialized authentication may be required in simple instances. The provided data suggests a high exploitability factor.
  • Publicly Known Exploits: No publicly available exploit code is mentioned in the provided data, however, SQL injection vulnerabilities are well-understood and often easily exploited. It is likely that attackers will develop and use exploits.
  • Exploitation Complexity: SQL Injection is a well-known and relatively easy to exploit vulnerability. Attackers with basic SQL knowledge can likely exploit it.
  • Known Attacks in the Wild: The data does not explicitly state that this vulnerability is being actively exploited in the wild, but given the severity and ease of exploitability, it is highly probable that attacks are occurring or will occur soon.

4. Remediation Strategy

The primary and recommended remediation is to upgrade to WeGIA version 3.2.13 or later. This version contains a patch that addresses the SQL injection vulnerability.

  • Step 1: Assessment and Planning:
    • Identify all instances of the WeGIA application within your environment.
    • Determine the current version of WeGIA installed on each instance.
    • Plan a schedule for upgrading each instance to version 3.2.13 or later. Prioritize systems containing sensitive data or critical functionality.
  • Step 2: Upgrade to Version 3.2.13 or Later:
    • Follow the official WeGIA upgrade instructions carefully.
    • Before upgrading the production environment, test the upgrade in a non-production environment to ensure compatibility and functionality.
    • Back up the WeGIA database and application files before performing the upgrade.
  • Step 3: Verification and Validation:
    • After the upgrade, verify that the SQL injection vulnerability has been successfully remediated. This can be done through:
      • Penetration Testing: Engage a security professional to perform a penetration test to specifically target the documento_excluir.php endpoint and other potential SQL injection points.
      • Vulnerability Scanning: Use a web vulnerability scanner to automatically identify SQL injection vulnerabilities.
    • Validate that the WeGIA application is functioning correctly after the upgrade.

5. Mitigation Strategy (If Upgrade is Not Immediately Possible)

If an immediate upgrade to version 3.2.13 or later is not possible, implement the following mitigation measures to reduce the risk of exploitation:

  • Input Validation and Sanitization: Implement strict input validation and sanitization on the documento_excluir.php endpoint. This involves:
    • Validating all user inputs against a whitelist of allowed characters and formats.
    • Sanitizing user inputs by escaping special characters that could be interpreted as SQL commands. Use parameterized queries or prepared statements.
  • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block SQL injection attempts. Configure the WAF with rules specifically designed to protect against SQL injection attacks targeting the documento_excluir.php endpoint.
  • Database Access Control: Restrict database access privileges for the WeGIA application. Grant the application only the minimum required privileges to perform its necessary functions. Avoid using the root or administrator account for the application.
  • Network Segmentation: If possible, segment the WeGIA application server from other critical systems on the network. This will limit the potential impact of a successful SQL injection attack.
  • Monitoring and Logging: Enable detailed logging of all database activity. Monitor logs for suspicious activity, such as unusual SQL queries or failed login attempts. Set up alerts to notify administrators of potential SQL injection attacks.

6. General Security Best Practices

In addition to the specific remediation and mitigation measures outlined above, follow these general security best practices:

  • Regular Security Audits: Conduct regular security audits of the WeGIA application and its underlying infrastructure.
  • Keep Software Up-to-Date: Keep all software, including the operating system, web server, and database server, up-to-date with the latest security patches.
  • Principle of Least Privilege: Grant users only the minimum privileges necessary to perform their tasks.
  • Security Awareness Training: Provide security awareness training to users and developers to educate them about SQL injection and other common web application vulnerabilities.

7. Disclaimer

This remediation/mitigation strategy is based on the information provided and should be considered a starting point. It is essential to perform a thorough assessment of your specific environment and tailor the remediation and mitigation measures accordingly. Consult with security professionals for expert guidance.
