Remediation/Mitigation Strategy for CVE-2025-26614 - SQL Injection in WeGIA

This document outlines the remediation and mitigation strategy for the SQL Injection vulnerability (CVE-2025-26614) discovered in the WeGIA web application.

1. Vulnerability Description:

  • Vulnerability: SQL Injection
  • Location: deletar_documento.php endpoint within the WeGIA application.
  • Description: The WeGIA application, a Web Manager for Institutions primarily used by Portuguese language users, contains a SQL Injection vulnerability in the deletar_documento.php endpoint. This vulnerability allows an authorized attacker to inject malicious SQL queries into the application’s database interactions. This can lead to the unauthorized access, modification, or deletion of sensitive information stored in the database.

2. Severity Assessment:

  • CVSS Score: 9.4 (Critical)
  • Vector: As indicated in the provided data, the CVSS score is 9.4, indicating critical severity. (This score reflects a high risk of exploitation and impact).
  • Impact:
    • Confidentiality: High - Sensitive information can be accessed by unauthorized individuals.
    • Integrity: High - Data can be modified or deleted, leading to data corruption or loss.
    • Availability: Potentially High - The application or database could be rendered unavailable due to malicious queries.

3. Known Exploit:

  • The provided information does not indicate a specific, detailed public exploit. However, the fact that it’s a SQL Injection vulnerability means that standard SQL injection techniques can likely be used. Therefore, it should be considered easily exploitable by anyone with basic SQL injection knowledge.
  • Exploitability: High - SQL Injection is a well-understood vulnerability with readily available tools and techniques for exploitation.
  • No Workarounds: The advisory specifically states “There are no known workarounds for this vulnerability.”

4. Remediation Strategy:

  • Immediate Action: Upgrade to WeGIA version 3.2.14 or later IMMEDIATELY. This is the primary and recommended solution.
  • Verification: After upgrading, thoroughly test the deletar_documento.php endpoint (and other areas that interact with the database) to ensure the vulnerability is no longer present. Use penetration testing or vulnerability scanning tools to confirm the fix.
  • Database Security Review: Conduct a thorough review of the database security configuration, including user permissions and access controls. Ensure that the principle of least privilege is enforced.
  • Code Review: Perform a comprehensive code review of the WeGIA application, focusing on database interactions and input validation. Identify and address any other potential SQL injection vulnerabilities.

5. Mitigation Strategy (If Immediate Upgrade is Not Possible - NOT RECOMMENDED):

  • Important Note: Upgrading is the preferred and highly recommended solution. The following mitigation steps are only temporary measures and should be implemented with caution and carefully considered risks. They are not a substitute for upgrading.
  • Input Validation: Implement strict input validation and sanitization on all user-supplied data before it is used in SQL queries. This includes:
    • Whitelisting: Define a strict whitelist of allowed characters and data formats.
    • Escaping: Properly escape all special characters that could be interpreted as SQL syntax. Use the database’s built-in escaping mechanisms.
    • Parameterized Queries/Prepared Statements: Use parameterized queries or prepared statements whenever possible. This is the most effective way to prevent SQL injection.
  • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) and configure it with rules to detect and block SQL injection attempts.
  • Database Monitoring: Implement database monitoring to detect suspicious activity, such as unusual SQL queries or unauthorized access attempts.
  • Principle of Least Privilege: Ensure that the database user account used by the WeGIA application has only the minimum necessary privileges. Avoid using a database administrator account for the application.

6. Communication:

  • Inform Users: Notify all users of the WeGIA application about the vulnerability and the steps being taken to address it.
  • Monitor Security Advisories: Stay informed about future security advisories for WeGIA and other software used in your environment.

7. Long-Term Security Practices:

  • Secure Coding Training: Provide secure coding training to developers to help them avoid introducing vulnerabilities into the application.
  • Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities before they can be exploited.
  • Vulnerability Scanning: Implement automated vulnerability scanning tools to continuously monitor the application for known vulnerabilities.
  • Security Development Lifecycle (SDL): Implement a Security Development Lifecycle (SDL) to integrate security considerations into all phases of the software development process.

Disclaimer: This remediation/mitigation strategy is based on the information provided in the security advisory. The specific steps required may vary depending on your environment and configuration. It is recommended to consult with a security expert to develop a tailored solution.
