CVE-2025-27096

Remediation/Mitigation Strategy for CVE-2025-27096 - WeGIA SQL Injection

Vulnerability Description:

  • Vulnerability: SQL Injection
  • Affected Software: WeGIA (Web Manager for Institutions)
  • Affected Endpoint: personalizacao_upload.php
  • Description: An authenticated attacker can exploit a SQL injection vulnerability in the personalizacao_upload.php endpoint of the WeGIA application. This allows the attacker to execute arbitrary SQL queries against the application’s database, potentially leading to unauthorized access to sensitive information, modification of data, or even complete compromise of the database.

Severity:

  • CVSS Score: 9.8 (Critical)
  • CVSS Vector: (Based on provided data, assuming a standard Network vector, Authentication Required, High Confidentiality, Integrity and Availability impact): AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
  • Impact:
    • Confidentiality: High - Sensitive information can be accessed.
    • Integrity: High - Data can be modified or deleted.
    • Availability: High - The application or database can be rendered unavailable.

Known Exploit:

  • The vulnerability is exploitable, as indicated by its critical severity score.
  • The report indicates that authenticated access is required, so exploitation requires a valid user account. However, given the impact and ease of exploitation (SQL Injection), it’s highly likely that proof-of-concept exploits or active exploitation is occurring or will occur soon.

Remediation Strategy:

  1. Immediate Action: Upgrade to Version 3.2.14 (or later):

    • The vendor, GitHub, explicitly states that this issue has been addressed in WeGIA version 3.2.14. This is the primary and recommended mitigation. Upgrade your WeGIA instance to this version as soon as possible. Follow the vendor’s upgrade instructions carefully.
    • Verify the successful upgrade by checking the WeGIA version number after the upgrade.

  2. Verification and Validation:

    • After upgrading, thoroughly test the personalizacao_upload.php endpoint, as well as other related functionalities that might have used the same vulnerable code patterns, to confirm that the SQL injection vulnerability has been successfully patched. Use penetration testing tools and techniques to simulate potential attacks.
    • Review the application’s changelog or release notes for WeGIA 3.2.14 to understand the specific changes made to address the SQL injection vulnerability.

  3. Security Best Practices (Ongoing):

    • Input Validation: Implement robust input validation and sanitization on all user-supplied data, especially for database queries. Use parameterized queries or prepared statements to prevent SQL injection. This should be implemented across the entire application, not just the vulnerable endpoint.
    • Least Privilege Principle: Ensure that database user accounts used by the WeGIA application have only the necessary privileges to perform their intended tasks. Avoid using database accounts with excessive permissions.
    • Web Application Firewall (WAF): Consider deploying a WAF to detect and block malicious SQL injection attempts. Configure the WAF with rules specifically designed to prevent SQL injection attacks. Regularly update WAF rules to stay protected against new attack vectors.
    • Regular Security Audits: Conduct regular security audits and penetration testing of the WeGIA application to identify and address potential vulnerabilities.
    • Code Review: Implement a secure code review process to identify and prevent vulnerabilities during the development lifecycle. Focus on identifying potential SQL injection vulnerabilities and other common web application security flaws.
    • Security Training: Provide security awareness training to developers and administrators to educate them about SQL injection vulnerabilities and other security risks.

Mitigation Strategy (If Upgrade is Immediately Impossible):

  • There are no known workarounds for this vulnerability besides upgrading. The vendor specifically states this. If upgrading is completely impossible in the very short term (which is highly discouraged), the following temporary and partial mitigation strategies might reduce the risk, but they are not a replacement for upgrading:

    • Network Segmentation: If possible, segment the WeGIA application server into a restricted network segment with limited access from other systems. This can limit the potential impact of a successful exploit.
    • Monitor Access Logs: Enable detailed access logging on the WeGIA application server and database server. Monitor these logs for suspicious activity, such as unusual SQL queries or access to sensitive data. This is a reactive measure, but it can help detect and respond to an attack in progress. Specifically monitor access logs from personalizacao_upload.php
    • Disable the Vulnerable Endpoint (If Feasible): If the personalizacao_upload.php endpoint is not essential for the application’s functionality, consider temporarily disabling it until the upgrade can be performed. This will prevent attackers from exploiting the vulnerability through this specific endpoint. Evaluate business impact before disabling.

Important Considerations:

  • The provided data emphasizes that upgrading to version 3.2.14 is the solution. The “mitigation” steps above are only temporary measures to reduce risk until the upgrade can be performed.
  • Thoroughly test the application after applying any mitigation steps to ensure that they do not introduce new issues.
  • Stay informed about security advisories and updates for WeGIA and other related software.
  • Maintain a robust incident response plan in case of a successful exploit. Know how to isolate the affected system, contain the damage, and restore services.
