CVE-2025-27648: Vasion Print Information Disclosure Flaw

CVE-2025-27648 Overview

CVE-2025-27648 is a critical vulnerability affecting Vasion Print (formerly PrinterLogic) that allows Cross Tenant Password Exposure. This vulnerability, tracked as V-2024-003, exists in versions prior to Virtual Appliance Host 22.0.913 and Application 20.0.2253. The flaw enables unauthorized access to password information across tenant boundaries in multi-tenant deployments, representing a severe breach of tenant isolation controls.

Critical Impact

This vulnerability allows attackers to access sensitive password credentials across tenant boundaries without authentication, potentially compromising all tenants in a shared PrinterLogic environment.

Affected Products

• Vasion Print (formerly PrinterLogic) versions prior to Application 20.0.2253
• PrinterLogic Virtual Appliance versions prior to Host 22.0.913
• All multi-tenant PrinterLogic deployments using vulnerable versions

Technical Details for CVE-2025-27648

Vulnerability Analysis

This vulnerability stems from inadequate credential protection mechanisms within the Vasion Print (PrinterLogic) platform. The flaw is categorized under CWE-522 (Insufficiently Protected Credentials), indicating that password data is not properly secured within the application's multi-tenant architecture. An attacker exploiting this vulnerability can access password information belonging to other tenants within the same PrinterLogic deployment, effectively bypassing tenant isolation controls that are fundamental to secure multi-tenant environments.

The vulnerability is exploitable remotely over the network without requiring any authentication or user interaction, making it particularly dangerous for organizations using PrinterLogic in shared hosting or multi-tenant configurations. The impact spans confidentiality, integrity, and availability, as exposed credentials could be leveraged for further attacks against affected tenant environments.

Root Cause

The root cause of CVE-2025-27648 lies in insufficiently protected credentials (CWE-522) within the PrinterLogic application. The platform fails to properly isolate and protect password data between different tenants, allowing cross-tenant information disclosure. This represents a fundamental flaw in the tenant separation architecture where credential storage or retrieval mechanisms do not enforce proper tenant boundaries.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no prior authentication or special privileges. An attacker can exploit this vulnerability remotely to access password information from other tenants. The exploitation requires low complexity and does not depend on user interaction, making it a high-priority threat for any organization running vulnerable versions of PrinterLogic in a multi-tenant configuration.

The vulnerability enables an attacker to:

1. Access the PrinterLogic application over the network
2. Exploit the cross-tenant password exposure flaw
3. Retrieve password credentials belonging to other tenants
4. Use harvested credentials for lateral movement or further attacks

Detection Methods for CVE-2025-27648

Indicators of Compromise

• Unexpected cross-tenant API calls or data access patterns in PrinterLogic logs
• Authentication events using credentials from multiple tenant contexts
• Anomalous access to credential storage or password management functions
• Unusual network traffic patterns to PrinterLogic Virtual Appliance endpoints

Detection Strategies

• Monitor PrinterLogic application logs for unauthorized cross-tenant access attempts
• Implement network monitoring for suspicious traffic to PrinterLogic services
• Deploy intrusion detection rules targeting credential enumeration behaviors
• Review audit logs for access patterns that violate tenant boundaries

Monitoring Recommendations

• Enable verbose logging on PrinterLogic Virtual Appliance instances
• Configure SIEM alerting for cross-tenant access patterns in PrinterLogic environments
• Monitor authentication logs for credential usage anomalies across tenant boundaries
• Implement network segmentation monitoring between PrinterLogic instances and client networks

How to Mitigate CVE-2025-27648

Immediate Actions Required

• Upgrade Vasion Print to Application version 20.0.2253 or later immediately
• Update Virtual Appliance to Host version 22.0.913 or later
• Rotate all passwords and credentials that may have been exposed through vulnerable instances
• Review access logs for signs of unauthorized cross-tenant access
• Isolate vulnerable PrinterLogic instances from network access until patching is complete

Patch Information

Vasion (formerly PrinterLogic) has released patched versions that address this vulnerability. Organizations should upgrade to Virtual Appliance Host version 22.0.913 or later with Application version 20.0.2253 or later. Detailed patching instructions and security bulletins are available from the PrinterLogic Security Bulletins page.

Additional technical details about this and related PrinterLogic vulnerabilities have been documented by security researchers. For further information, see the Pierre Kim Blog on PrinterLogic Vulnerabilities and the Full Disclosure Mailing List April Post.

Workarounds

• Restrict network access to PrinterLogic Virtual Appliance to trusted IP ranges only
• Implement additional network segmentation between tenant environments
• Deploy web application firewall rules to monitor and filter PrinterLogic traffic
• Consider temporarily disabling multi-tenant features until patching is complete
• Monitor all credential-related activities in PrinterLogic environments pending upgrade
