CVE-2025-26617

Remediation/Mitigation Strategy: WeGIA SQL Injection Vulnerability (CVE-2025-26617)

This document outlines the remediation and mitigation strategy for the SQL Injection vulnerability (CVE-2025-26617) discovered in the WeGIA application.

1. Vulnerability Description:

  • Vulnerability: SQL Injection
  • Affected Component: historico_paciente.php endpoint in WeGIA application
  • Description: A SQL Injection vulnerability exists in the historico_paciente.php endpoint. This vulnerability allows an attacker to inject malicious SQL code into queries executed by the application. Successful exploitation can grant the attacker unauthorized access to sensitive information stored in the database. This can include patient records, user credentials, and other confidential data.
  • Affected Version: WeGIA versions prior to 3.2.14
  • Source: GitHub Security Advisory ([email protected], 202500026617)

2. Severity:

  • CVSS Score: 10.0 (Based on data provided)
  • Severity Level: Critical
  • Rationale: SQL Injection vulnerabilities are considered critical due to their potential for complete database compromise. An attacker can not only read sensitive data but also modify or delete data, potentially disrupting the application’s functionality and impacting data integrity and confidentiality. The CVSS score of 10.0 indicates a highly exploitable vulnerability with severe consequences.

3. Known Exploit:

  • Based on the advisory, there is a known exploit. While the specific exploit details aren’t provided, the advisory states that attackers can “execute arbitrary SQL queries, allowing unauthorized access to sensitive information.” This means the vulnerability is actively exploitable.

4. Remediation Strategy:

The primary remediation strategy is to upgrade to the latest version of WeGIA.

  • Action: Upgrade WeGIA to version 3.2.14 or later. This version contains a patch that addresses the SQL Injection vulnerability in historico_paciente.php.

  • Procedure:

    1. Backup: Before upgrading, create a full backup of the WeGIA application and its database. This will allow you to restore the system to its previous state if any issues arise during the upgrade process.
    2. Download: Download the latest version (3.2.14 or later) of WeGIA from the official WeGIA website or a trusted source.
    3. Installation: Follow the upgrade instructions provided in the WeGIA documentation to install the new version.
    4. Verification: After the upgrade, verify that the application is functioning correctly and that the historico_paciente.php endpoint is no longer vulnerable to SQL Injection. You can use a web application security scanner or manual testing techniques to confirm this.

5. Mitigation Strategy (if immediate upgrade is not possible):

If an immediate upgrade is not possible, implement the following mitigation measures:

  • Input Validation: Implement strict input validation on all user inputs to the historico_paciente.php endpoint. Sanitize and escape all input values before using them in SQL queries. This should include whitelisting allowed characters and rejecting any input that contains potentially malicious SQL code.
  • Parameterized Queries (Prepared Statements): Use parameterized queries (also known as prepared statements) in all database interactions. Parameterized queries separate the SQL code from the data, preventing the SQL engine from interpreting user-supplied data as code. This is a highly effective method for preventing SQL Injection attacks.
  • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to filter malicious traffic and block SQL Injection attempts. Configure the WAF with rules to detect and block common SQL Injection patterns.
  • Database Permissions: Review and restrict database permissions. Ensure that the WeGIA application only has the necessary permissions to access the data it needs. Avoid granting the application excessive privileges.
  • Monitoring and Alerting: Implement monitoring and alerting to detect suspicious activity, such as unusual database queries or failed login attempts. Set up alerts to notify administrators of any potential security incidents.

6. Timeline:

  • Immediate: Begin planning and executing the upgrade process.
  • Within 24 hours: Apply mitigation measures (input validation, parameterized queries, WAF) if an immediate upgrade is not possible.
  • Within 72 hours: Complete the upgrade to WeGIA version 3.2.14 or later.
  • Ongoing: Continuously monitor the application for suspicious activity and review security configurations.

7. Roles and Responsibilities:

  • System Administrators: Responsible for upgrading the WeGIA application and implementing mitigation measures.
  • Database Administrators: Responsible for reviewing and restricting database permissions.
  • Security Team: Responsible for deploying and configuring the WAF, monitoring for suspicious activity, and validating the effectiveness of the remediation and mitigation efforts.

8. Post-Remediation Activities:

  • Vulnerability Scanning: After the upgrade, perform a vulnerability scan to ensure that the SQL Injection vulnerability has been successfully addressed and that no new vulnerabilities have been introduced.
  • Penetration Testing: Consider conducting a penetration test to simulate a real-world attack and identify any remaining security weaknesses.
  • Security Awareness Training: Provide security awareness training to developers and system administrators to educate them about SQL Injection vulnerabilities and how to prevent them.

By following this remediation and mitigation strategy, you can effectively address the SQL Injection vulnerability in WeGIA and protect your sensitive data from unauthorized access. Prioritize upgrading to the patched version of WeGIA as the most effective and permanent solution. Remember to always test upgrades in a non-production environment before deploying them to production.
