CVE-2025-21619

Remediation / Mitigation Strategy for CVE-2025-21619: GLPI SQL Injection

Vulnerability Description:

  • Vulnerability: SQL Injection
  • Affected Software: GLPI (a free asset and IT management software package)
  • Version Affected: GLPI versions prior to 10.0.18
  • Location: Rules configuration forms
  • Attacker Privilege: Administrator User

Severity:

  • CVSS Score: 8.2 (High) - Based on the provided data.
  • Impact: A successful SQL Injection attack can allow an attacker with administrator privileges to:
    • Data Breach: Access sensitive data stored in the GLPI database, including user credentials, asset information, configuration details, and potentially other confidential data.
    • Data Modification: Modify or delete data within the GLPI database, potentially disrupting IT operations, altering asset information, or causing system instability.
    • Privilege Escalation: Potentially escalate privileges beyond the administrator role if the underlying database user has broader permissions.
    • Remote Code Execution (Potential): Depending on the database server configuration and permissions, the attacker might be able to execute arbitrary code on the database server or the GLPI server itself.

Known Exploit:

  • The provided data confirms that an exploit exists, as it states an Administrator user can perform SQL injection through the rules configuration forms. While the exact exploit details aren’t given, it’s confirmed to be functional.

Remediation Strategy:

The primary remediation is to upgrade to the patched version. Secondary controls should be used to mitigate risk until the upgrade is possible.

  1. Immediate Action: Upgrade GLPI to version 10.0.18 or later. This is the most effective and recommended solution. Download the latest version from the official GLPI website or repository. Follow the official GLPI upgrade instructions carefully. Do not skip this step.

  2. Short-Term Mitigation (If immediate upgrade is not possible):

    • Restrict Access: Limit access to the rules configuration forms to only the absolutely necessary administrator users. Implement strict role-based access control (RBAC) within GLPI.
    • Input Validation Review (Difficult and Not Recommended): Manually review and harden the input validation routines for the rules configuration forms. This is highly discouraged as a standalone solution. It is difficult to implement correctly and can easily be bypassed. It requires deep knowledge of the GLPI codebase and SQL injection techniques. If attempted, consult with experienced security developers.
    • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) in front of the GLPI instance. Configure the WAF with rules to detect and block SQL injection attempts targeting the GLPI application. Regularly update the WAF ruleset.

  3. Long-Term Prevention:

    • Security Audits: Conduct regular security audits and penetration testing of the GLPI instance and its underlying infrastructure to identify and address potential vulnerabilities.
    • Secure Coding Practices: Enforce secure coding practices for any custom GLPI plugins or modifications. Ensure that all code undergoes thorough security review.
    • Database Hardening: Harden the database server hosting the GLPI database. Follow database security best practices, including:
      • Use strong passwords for all database users.
      • Limit database user permissions to the minimum required for GLPI to function.
      • Keep the database server software up to date with the latest security patches.
      • Disable unnecessary database features.
    • Intrusion Detection System (IDS) / Intrusion Prevention System (IPS): Implement an IDS/IPS to monitor network traffic for malicious activity targeting the GLPI instance.

Implementation Steps:

  1. Planning: Create a detailed plan for the upgrade, including backup procedures, testing schedules, and communication plans.
  2. Backup: Back up the entire GLPI instance, including the database and application files, before making any changes. Verify the integrity of the backup.
  3. Upgrade: Perform the GLPI upgrade according to the official documentation.
  4. Testing: Thoroughly test the upgraded GLPI instance to ensure that it is functioning correctly and that the vulnerability has been remediated. Focus testing on the rules configuration forms.
  5. Monitoring: Continuously monitor the GLPI instance for any signs of suspicious activity.

Communication Plan:

  • Notify all affected users about the vulnerability and the remediation steps being taken.
  • Provide regular updates on the progress of the remediation effort.

Important Considerations:

  • Administrator Access: The fact that this vulnerability requires administrator access doesn’t diminish its severity. Compromising an administrator account is a common attack vector.
  • Database Permissions: Carefully review the permissions of the database user that GLPI uses to connect to the database. Restrict permissions to the minimum necessary to prevent privilege escalation if SQL injection is successful.
  • Patch Release Cadence: Establish a process for promptly applying security patches to GLPI and other critical infrastructure components.
  • Vulnerability Scanning: Implement regular vulnerability scanning of your GLPI installation to proactively identify and address security issues.

This remediation strategy provides a comprehensive approach to addressing the CVE-2025-21619 SQL injection vulnerability in GLPI. By following these steps, organizations can significantly reduce their risk of exploitation and protect their sensitive data. Remember to prioritize the upgrade to the latest patched version as the most effective solution.
