CVE-2025-26609

Remediation/Mitigation Strategy: WeGIA SQL Injection Vulnerability (CVE-2025-26609)

This document outlines the remediation strategy for the SQL Injection vulnerability discovered in the WeGIA application, specifically in the familiar_docfamiliar.php endpoint (CVE-2025-26609).

1. Vulnerability Description:

  • Vulnerability: SQL Injection
  • Location: familiar_docfamiliar.php endpoint in WeGIA application.
  • Description: The WeGIA application, a web manager for institutions focusing on Portuguese language users, contains a SQL Injection vulnerability. This vulnerability allows an attacker to inject malicious SQL code into the application’s queries. Successful exploitation can lead to unauthorized access to sensitive data, modification of data, or even complete database compromise.

2. Severity:

  • Severity: Critical
  • CVSS Score: 10.0 (Based on provided data)
  • Rationale: SQL injection vulnerabilities are considered critical due to the potential for complete compromise of the database and associated systems. The high CVSS score confirms this severity assessment. Unauthorized access to and modification of sensitive information can have severe consequences, including data breaches, financial loss, and reputational damage.

3. Known Exploit:

  • Exploitability: Exploitable
  • Details: While the specific exploit code is not detailed in the provided advisory, the existence of a SQL Injection vulnerability implies that an attacker could craft malicious SQL queries (likely through manipulated input parameters to familiar_docfamiliar.php) to extract data, modify data, or execute arbitrary commands within the database.
  • Attack Vector: Network. Attackers can exploit this vulnerability remotely if the WeGIA application is exposed to the internet or an untrusted network.

4. Remediation Strategy:

The primary and recommended remediation strategy is to upgrade to WeGIA version 3.2.14 or later. This version contains the fix for the SQL Injection vulnerability.

Steps:

  1. Immediate Action: Upgrade WeGIA: The highest priority is to upgrade all instances of WeGIA to version 3.2.14 as soon as possible.

    • Consult the WeGIA documentation for upgrade instructions: [Replace with actual link to official WeGIA upgrade documentation]
    • Thoroughly test the upgraded application in a staging environment before deploying it to production.

  2. Verification: After the upgrade, verify that the familiar_docfamiliar.php endpoint is no longer vulnerable to SQL Injection.

    • Perform penetration testing or vulnerability scanning to confirm the fix.
    • Review the code changes related to familiar_docfamiliar.php in version 3.2.14 to understand how the vulnerability was addressed.

5. Mitigation (If immediate upgrade is not possible - NOT RECOMMENDED):

  • There are no known workarounds suggested in the security advisory. Continuing to use a vulnerable version without an upgrade is strongly discouraged. However, if an immediate upgrade is absolutely not feasible, the following temporary mitigations, implemented in conjunction, may reduce the risk:

    1. Input Validation: Implement rigorous input validation on all parameters passed to familiar_docfamiliar.php. This includes:

      • Whitelisting: Define acceptable patterns for input and reject any input that does not conform to these patterns.
      • Escaping: Properly escape all user-supplied input before using it in SQL queries. Use the database system’s built-in escaping functions (e.g., mysqli_real_escape_string in PHP with MySQL).
      • Data Type Enforcement: Ensure that data types are correctly enforced. For example, if a parameter is expected to be an integer, reject any input that is not an integer.

    2. Principle of Least Privilege: Ensure that the database user account used by the WeGIA application has only the minimum necessary privileges. Avoid using a privileged account like root or an account with GRANT ALL privileges.

    3. Web Application Firewall (WAF): Deploy a WAF in front of the WeGIA application. Configure the WAF to block known SQL Injection attack patterns.

    4. Database Activity Monitoring: Implement database activity monitoring to detect and alert on suspicious SQL queries.

    Important Considerations for Mitigation:

    • These mitigations are not a substitute for upgrading. They only provide a temporary reduction in risk.
    • Implementing input validation and escaping correctly can be complex and prone to errors. Incorrect implementation can lead to bypasses.
    • Regularly review and update the input validation rules and WAF rules to stay ahead of evolving attack techniques.

6. Long-Term Security Practices:

  • Secure Coding Practices: Train developers on secure coding practices, including how to prevent SQL Injection vulnerabilities.
  • Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities.
  • Vulnerability Scanning: Implement automated vulnerability scanning to identify known vulnerabilities in third-party libraries and components.
  • Patch Management: Establish a robust patch management process to ensure that all systems are promptly patched with the latest security updates.

7. Reporting and Communication:

  • Report the incident to the appropriate security teams and management.
  • Communicate the remediation plan and progress to stakeholders.

Disclaimer: This remediation strategy is based on the limited information provided in the security advisory. It is recommended to consult with security experts and review the WeGIA documentation for more detailed guidance.
