CVE-2025-27664

Remediation/Mitigation Strategy: CVE-2025-27664

This document outlines the vulnerability, severity, potential exploit, and recommended remediation/mitigation strategies for CVE-2025-27664, affecting Vasion Print (formerly PrinterLogic).

1. Vulnerability Description:

  • CVE ID: CVE-2025-27664
  • Component Affected: Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.843 Application 20.0.1923
  • Description: Insufficient Cross-Site Request Forgery (CSRF) Protection. This means that an attacker can potentially trick a user into performing actions on the Vasion Print system without their knowledge or consent. This can lead to unauthorized changes to printer configurations, access control modifications, or other administrative actions, depending on the specific functions lacking CSRF protection.

2. Severity Assessment:

  • CVSS Score: 8.8 (High)
  • CVSS Vector: (Based on the provided data): AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (Interpretation: Network, Low Attack Complexity, No Privileges Required, User Interaction Required, Scope Unchanged, High Confidentiality Impact, High Integrity Impact, High Availability Impact)
  • Severity: High
  • Explanation: A successful CSRF attack can have significant impact, allowing an attacker to compromise the confidentiality, integrity, and availability of the printing infrastructure. The high CVSS score reflects the potential for widespread and severe consequences. User interaction is required (clicking a malicious link, visiting a compromised website), but the low attack complexity makes exploitation relatively easy.

3. Known Exploits:

While the provided data doesn’t explicitly describe a known exploit, the nature of CSRF vulnerabilities means exploiting this issue is likely straightforward. An attacker could:

  • Craft Malicious Links/HTML: Create a malicious link or embed HTML code on a website (or in an email) that, when clicked/viewed by an authenticated user, sends a forged request to the Vasion Print server.
  • Target Common Admin Actions: Focus on commonly used administrative functions like:
    • Adding or removing printers
    • Modifying printer configurations (e.g., default settings, access controls)
    • Changing user permissions
    • Initiating print jobs (potentially exfiltrating documents)
  • Phishing: Combine the crafted links with a phishing campaign to increase the likelihood of user interaction.

4. Remediation/Mitigation Strategy:

The primary remediation is to upgrade the Vasion Print software to a version later than Virtual Appliance Host 22.0.843 Application 20.0.1923 that addresses the CSRF vulnerability. If upgrading is not immediately possible, implement the following mitigations:

  • Immediate Action: Upgrade Vasion Print:

    • The highest priority is to upgrade to the latest version of Vasion Print provided by the vendor. Consult the vendor’s documentation for the upgrade procedure. This should include the CSRF protection fix.
    • Verify the upgrade resolves CVE-2025-27664, either by checking the release notes or by conducting a vulnerability scan after the upgrade.

  • Short-Term Mitigations (Until Upgrade): These provide a degree of defense but are not substitutes for patching.

    • Browser Security Extensions: Encourage users to install and use browser extensions designed to prevent CSRF attacks (e.g., Anti-CSRF Tokens extension).
    • User Awareness Training: Conduct user awareness training to educate employees about the risks of phishing and malicious links. Emphasize the importance of verifying the authenticity of links before clicking them and being cautious of unsolicited emails.
    • Monitor Access Logs: Closely monitor Vasion Print access logs for suspicious activity, such as:
      • Unusual changes to printer configurations.
      • Unexpected creation of new user accounts or privilege escalations.
      • Unfamiliar IP addresses accessing the system.
      • High volume or unusual print activity.
    • Firewall Restrictions (If Possible): Limit access to the Vasion Print server to only authorized IP addresses or networks. This will reduce the attack surface.
    • Referer Header Checking (If Applicable): Investigate if the Vasion Print application can be configured to check the Referer header in HTTP requests. This can provide some protection against CSRF, but it’s not a foolproof solution as Referer headers can sometimes be spoofed or omitted.

  • Long-Term Security Improvements:

    • Implement CSRF Protection: Ensure all new and existing web applications, including administrative interfaces, incorporate proper CSRF protection mechanisms. This typically involves the use of:

      • Synchronizer Tokens (CSRF Tokens): Generating unique, unpredictable tokens for each user session and embedding them in forms and URLs. The server verifies the token on each request.
      • Double Submit Cookies: Setting a cookie with a random value and including the same value as a hidden field in forms. The server verifies that both values match.
      • SameSite Cookie Attribute: Using the SameSite attribute for cookies to control when they are sent in cross-site requests.

    • Regular Vulnerability Scanning: Implement regular vulnerability scanning of the Vasion Print system and other network devices to identify and address potential security weaknesses proactively.

    • Security Audits: Conduct periodic security audits of the Vasion Print configuration and deployment to ensure adherence to security best practices.

5. Communication:

  • Communicate the vulnerability and the importance of the upgrade to all affected users and administrators.
  • Provide clear instructions on how to upgrade the Vasion Print software.
  • Explain the mitigations that should be implemented while awaiting the upgrade.
  • Establish a process for reporting suspected security incidents related to Vasion Print.

6. Testing and Validation:

  • After implementing the upgrade, thoroughly test the Vasion Print system to ensure that the CSRF vulnerability has been resolved.
  • Conduct penetration testing to identify any remaining security weaknesses.

7. Rollback Plan:

  • Develop a rollback plan in case the upgrade causes unforeseen issues. This plan should include steps to revert to the previous version of Vasion Print and restore the system to its original state.

This remediation/mitigation strategy is a starting point. Adapt it based on your specific environment, risk tolerance, and the details of the Vasion Print deployment. Always consult the vendor’s documentation and support resources for the most accurate and up-to-date information.
