CVE-2025-27681: Vasion Print (formerly PrinterLogic) Client Inter-Process Security Mismanagement
This document outlines the remediation and mitigation strategy for CVE-2025-27681, a critical vulnerability affecting Vasion Print (formerly PrinterLogic) software.
1. Vulnerability Description:
- CVE ID: CVE-2025-27681
- Affected Product: Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 1.0.735 Application 20.0.1330
- Description: The vulnerability resides in the client inter-process security mechanism. Specifically, the software mishandles Client Inter-process Security V-2022-004, potentially allowing malicious processes to interact with and control the Vasion Print client in unintended ways. This can lead to unauthorized access, privilege escalation, and potentially remote code execution on the affected endpoint.
2. Severity:
- CVSSv3 Score: 9.8 (Critical)
- CVSSv3 Vector: Likely to be AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (Based on a CVSS score of 9.8, this is a likely vector and impact.)
- Explanation of probable vector:
- AV:N (Network): The vulnerability can likely be exploited over a network.
- AC:L (Low): Little or no special conditions are required to exploit the vulnerability.
- PR:N (None): No privileges are required to exploit the vulnerability.
- UI:N (None): No user interaction is required to exploit the vulnerability.
- S:U (Unchanged): An exploited vulnerability results in no change to the scope.
- C:H (High): High impact to confidentiality; there is a total information disclosure, resulting in all resources within the impacted component being divulged to the attacker.
- I:H (High): High impact to integrity; there is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being vulnerable.
- A:H (High): High impact to availability; there is a total denial of service, or a near total loss of access to resources, not only affecting the immediate victim but also having a knock-on effect on adjacent networks.
3. Known Exploits:
- While specific details of the exploit are not included in the initial data, the high CVSS score and description imply that a working exploit is highly probable or will become available soon. Given the “Network” vector and “No Privileges Required”, this exploit could be easily weaponized. Monitor threat intelligence feeds for updates and proof-of-concept exploits.
4. Remediation and Mitigation Strategy:
The primary goal is to quickly and effectively eliminate the vulnerability and minimize potential impact.
Immediate Actions:
- Apply Patch: The highest priority is to upgrade to Vasion Print Virtual Appliance Host version 1.0.735 Application 20.0.1330 or later. Apply the patch immediately upon release from Vasion. This is the primary and recommended remediation.
- Isolate Affected Systems (If Patching is Delayed): If patching cannot be performed immediately, isolate affected endpoints from the network to prevent potential exploitation. This includes restricting network access to only essential services.
Short-Term Mitigations (If Patching is Delayed):
- Implement Network Segmentation: Implement network segmentation to limit the blast radius of a potential compromise. Place Vasion Print clients in a separate network segment with strict access controls.
- Harden Endpoints:
- Ensure endpoints running the vulnerable Vasion Print client have up-to-date antivirus and endpoint detection and response (EDR) solutions installed and properly configured.
- Enable host-based firewalls and restrict network access to only necessary ports and services.
- Enforce strong password policies and multi-factor authentication where possible on user accounts.
- Monitor for Suspicious Activity: Implement robust monitoring and logging to detect potential exploitation attempts. Look for:
- Unusual network traffic originating from Vasion Print clients.
- Unexpected process execution or privilege escalation on endpoints.
- Unauthorized access to sensitive data or systems.
- Changes to system files or registry entries.
Long-Term Recommendations:
- Vulnerability Management Program: Implement a robust vulnerability management program to identify and address vulnerabilities in a timely manner.
- Software Configuration Management: Implement a system for tracking and managing software configurations to ensure consistency and security across all endpoints.
- Security Awareness Training: Provide security awareness training to users to help them identify and avoid phishing and other social engineering attacks that could lead to exploitation.
- Vendor Communication: Maintain open communication with Vasion (formerly PrinterLogic) to stay informed about security updates and best practices.
5. Testing and Validation:
- After applying the patch, thoroughly test the system to ensure that the vulnerability has been successfully remediated and that the application is functioning correctly.
- Consider using a vulnerability scanner to verify the patch and identify any other potential vulnerabilities.
- Perform penetration testing to simulate real-world attack scenarios and assess the effectiveness of the remediation efforts.
6. Communication Plan:
- Communicate the vulnerability and remediation plan to all relevant stakeholders, including IT staff, security personnel, and end-users.
- Provide regular updates on the progress of the remediation efforts.
- Establish a clear channel for reporting suspected security incidents.
7. Disclaimer:
This remediation strategy is based on the information available as of the date of this document. It is essential to consult with Vasion (formerly PrinterLogic) and other security experts to obtain the most up-to-date information and guidance. This document should not be considered a substitute for professional security advice. Given the critical nature and ease of exploitability, implementing the Immediate Actions is vital.
