CVE-2025-27673: Vasion Print (formerly PrinterLogic) Cookie Returned in Response Body Vulnerability

This document outlines the remediation and mitigation strategy for CVE-2025-27673, a vulnerability affecting Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.843 and Application 20.0.1923. This vulnerability allows for sensitive information disclosure due to cookies being returned in the response body.

1. Vulnerability Description:

  • CVE ID: CVE-2025-27673
  • Affected Software: Vasion Print (formerly PrinterLogic) Virtual Appliance Host before version 22.0.843 and Application before version 20.0.1923
  • Vulnerability Type: Sensitive Information Disclosure
  • Description: The vulnerability stems from the application incorrectly including cookie data within the response body. This exposes sensitive information contained in the cookie (such as session IDs, authentication tokens, or other user-specific data) to unintended parties. An attacker capable of intercepting or accessing the response body could then use this information for malicious purposes.
  • OVE ID: OVE-20230524-0017

2. Severity Assessment:

  • CVSS v3.1 Score: 9.1 (Critical)
  • CVSS v3.1 Vector: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
    • AV:N (Network): The vulnerability is exploitable over the network.
    • AC:L (Low): The vulnerability is easily exploitable with little effort.
    • 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): The vulnerability does not affect other components.
    • C:H (High): High impact to confidentiality; sensitive information is disclosed.
    • I:H (High): High impact to integrity; modification of system state is possible.
    • A:N (None): No impact to availability.
  • Severity: Critical

3. Known Exploit Information:

  • While specific exploit code might not be publicly available yet, the nature of the vulnerability (cookie information in the response body) makes it highly likely that successful exploits can be crafted relatively easily. An attacker could passively monitor network traffic or compromise systems capable of logging or accessing response data to extract cookie information.

4. Remediation and Mitigation Strategy:

A. Immediate Actions (Short-Term Mitigation):

  • 1. Upgrade Vasion Print (PrinterLogic): The most important action is to immediately upgrade to Vasion Print Virtual Appliance Host version 22.0.843 or later, and Application version 20.0.1923 or later. This patch contains the fix for the vulnerability.
  • 2. Web Application Firewall (WAF) Rules (If applicable): Implement or update WAF rules to detect and block responses containing cookie-like patterns in the body. This can provide a temporary layer of defense while upgrades are being planned and implemented. Consider rules that look for patterns like:
    • Set-Cookie: appearing in the response body.
    • Cookie: appearing in the response body.
    • Regular expressions that match the expected format of the cookies used by Vasion Print.
    • Caveat: WAF rules might lead to false positives. Monitor WAF logs closely.
  • 3. Network Monitoring: Implement and enhance network traffic monitoring to detect suspicious activity related to the Vasion Print server. Look for unusual traffic patterns or attempts to access sensitive data.
  • 4. Review Access Logs: Review Vasion Print access logs for any signs of unauthorized access or suspicious activity. Pay attention to any requests that might have triggered the vulnerability.
  • 5. Session Token Revocation (If Compromise is Suspected): If you suspect a compromise has occurred (e.g., you see unusual log entries, WAF alerts are triggered), revoke all active session tokens for Vasion Print users. This will force users to re-authenticate and invalidate any potentially stolen cookies.

B. Long-Term Remediation:

  • 1. Secure Configuration Review: After patching, perform a thorough security configuration review of the Vasion Print installation to ensure it is properly hardened and follows security best practices. This should include:
    • Ensuring the application is running with the least privileges necessary.
    • Disabling unnecessary features and services.
    • Implementing strong authentication mechanisms.
  • 2. Penetration Testing: Conduct regular penetration testing of the Vasion Print environment to identify and address any remaining vulnerabilities.
  • 3. Secure Development Practices: If the organization develops or customizes Vasion Print applications, implement secure development practices to prevent similar vulnerabilities from being introduced in the future. This includes:
    • Code reviews focused on security.
    • Static and dynamic code analysis.
    • Security training for developers.
  • 4. Regular Patching: Establish a process for regularly patching and updating Vasion Print software to address any newly discovered vulnerabilities.
  • 5. Security Awareness Training: Conduct security awareness training for users to educate them about the risks of phishing attacks and other social engineering techniques that could be used to steal their credentials and access the Vasion Print system.

C. Monitoring and Reporting:

  • 1. Continuous Monitoring: Continuously monitor the Vasion Print environment for any signs of compromise or suspicious activity.
  • 2. Security Incident Response Plan: Ensure there is a well-defined security incident response plan in place that outlines the steps to take in the event of a security breach.
  • 3. Reporting: Report the vulnerability to Vasion Print (formerly PrinterLogic) if you were not already notified.

5. Conclusion:

CVE-2025-27673 is a critical vulnerability that could lead to sensitive information disclosure. Prompt patching and implementation of the mitigation steps outlined above are essential to protect Vasion Print systems and data. Continuous monitoring and regular security assessments are crucial to maintain a secure environment. The primary remediation is to upgrade to the latest version of the software.
