Remediation/Mitigation Strategy for CVE-2025-27675: Vasion Print OpenID Vulnerability

This document outlines the remediation and mitigation strategy for CVE-2025-27675, a critical vulnerability affecting Vasion Print (formerly PrinterLogic).

1. Vulnerability Description:

  • CVE ID: CVE-2025-27675
  • Software Affected: Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.843 Application 20.0.1923
  • Vulnerability Type: Vulnerable OpenID Implementation (V-2023-004)
  • Description: The Vasion Print software contains a flaw in its OpenID implementation. This weakness could allow an attacker to potentially bypass authentication, impersonate users, or gain unauthorized access to sensitive information. Specific details of the vulnerability (e.g., how the OpenID implementation is flawed) are not provided in the original description, but the classification as a vulnerable OpenID implementation strongly suggests issues like improper validation of tokens, missing or incorrect audience checks, or vulnerabilities related to the OpenID Connect discovery endpoint.

2. Severity:

  • CVSS Score: 9.8 (Critical)

  • Severity Level: Critical

  • Justification: The high CVSS score indicates a critical vulnerability. The fact that it’s related to OpenID implies the potential for complete system compromise due to authentication bypass or privilege escalation. Successful exploitation could allow attackers to:

    • Access and modify sensitive print jobs.
    • Read printer configurations.
    • Impersonate administrators.
    • Potentially pivot to other systems on the network.

3. Known Exploits:

  • Based on the information provided, specific exploit details are not publicly available. However, given the critical severity and the “Vulnerable OpenID Implementation” description, exploits are highly likely to exist and could be rapidly developed.
  • Therefore, consider this vulnerability actively exploitable, even if public proof-of-concept code isn’t yet available.

4. Remediation Strategy:

The primary remediation is to immediately upgrade the Vasion Print software to a patched version.

  • Step 1: Upgrade Vasion Print:

    • Action: Upgrade your Vasion Print Virtual Appliance Host and Application to version 22.0.843 and 20.0.1923 or later, respectively. It is strongly advised to upgrade to the latest available versions to ensure all known security vulnerabilities are addressed.
    • Timeline: Immediate - this should be the highest priority.
    • Responsible Party: IT Security/System Administration Team
    • Verification: After upgrading, verify the installed version by checking the Vasion Print admin console or through the command line interface.
    • Rollback Plan: Create a backup of the current system before upgrading. If issues arise, restore from the backup to revert to the previous state. Ensure a valid backup exists and is tested before proceeding with the upgrade.

  • Step 2: Verify OpenID Configuration (Post-Upgrade):

    • Action: After upgrading, carefully review the OpenID configuration settings in Vasion Print. Verify that:
      • The redirect URIs are correctly configured and restricted.
      • The client secret is securely stored and rotated periodically.
      • The audience claim is properly validated.
      • All OpenID Connect flows are implemented securely (e.g., using PKCE).
    • Timeline: Within 24 hours of upgrade completion.
    • Responsible Party: IT Security/System Administration Team
    • Verification: Use a trusted OpenID Connect client to test authentication and authorization flows after the upgrade. Verify that tokens are correctly validated and that unauthorized access is prevented.

5. Mitigation Strategy (If immediate patching is not possible):

If you cannot immediately upgrade, implement the following temporary mitigations:

  • Disable OpenID Authentication: If feasible, temporarily disable OpenID authentication and revert to alternative authentication methods (e.g., local accounts, Active Directory integration). This is a drastic measure and should only be considered if the risk of leaving the vulnerability unpatched outweighs the disruption caused by disabling OpenID.

    • Timeline: Immediate, if chosen as a mitigation.
    • Responsible Party: IT Security/System Administration Team
    • Note: This will impact users relying on OpenID for authentication. Communicate this change clearly.

  • Network Segmentation: Isolate the Vasion Print system on a separate network segment with strict firewall rules. This can limit the potential impact of a successful exploit by preventing attackers from pivoting to other systems.

    • Timeline: Within 24 hours.
    • Responsible Party: Network Security Team

  • Web Application Firewall (WAF) Rules: Implement WAF rules to detect and block suspicious requests targeting the Vasion Print OpenID endpoints. These rules could look for: * Anomalous OpenID requests. * Attempts to manipulate OpenID parameters. * Requests containing suspicious characters or patterns.

    • Timeline: Within 48 hours.
    • Responsible Party: Web Application Security Team

  • Intrusion Detection/Prevention System (IDS/IPS) Monitoring: Configure your IDS/IPS to monitor traffic to and from the Vasion Print server for any signs of exploitation attempts.

    • Timeline: Within 48 hours.
    • Responsible Party: Security Operations Center (SOC)

Important Considerations:

  • Vendor Communication: Contact Vasion Print support for further guidance and clarification on the vulnerability and recommended remediation steps.
  • Monitoring: Continuously monitor the Vasion Print system for any signs of compromise or suspicious activity.
  • Regular Security Assessments: Conduct regular security assessments and penetration testing to identify and address vulnerabilities in your Vasion Print deployment.
  • Security Awareness Training: Ensure that all users are aware of the risks associated with phishing and social engineering attacks, which can be used to compromise OpenID credentials.

Disclaimer: This remediation/mitigation strategy is based on the limited information provided. It’s essential to consult with security experts and the vendor for specific guidance tailored to your environment. This strategy is a temporary measure until a full patch can be applied.

This document will be updated as more information becomes available.
