CVE-2025-27665: Vasion Print Information Disclosure Issue

CVE-2025-27665 Overview

CVE-2025-27665 is a critical vulnerability affecting Vasion Print (formerly PrinterLogic) that allows insufficient antivirus protection within the application. This security flaw enables printer drivers to contain known malicious code, potentially allowing attackers to distribute and execute malware through the trusted print management infrastructure. The vulnerability was tracked internally as OVE-20230524-0009.

Critical Impact

Attackers can leverage the insufficient antivirus protection to deploy malicious printer drivers containing known malware, potentially compromising enterprise print infrastructure and enabling network-wide attacks through trusted software distribution channels.

Affected Products

• Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions before 22.0.843
• Vasion Print Application versions before 20.0.1923
• PrinterLogic Virtual Appliance (all versions prior to the fixed release)

Technical Details for CVE-2025-27665

Vulnerability Analysis

This vulnerability represents a significant protection mechanism failure (CWE-693) within Vasion Print's driver handling system. The application fails to adequately scan and validate printer drivers for known malicious code signatures before allowing their installation and distribution across the enterprise print infrastructure.

In enterprise environments, print management solutions like Vasion Print are trusted to distribute printer drivers across the network. When antivirus protection is insufficient, malicious actors can inject compromised drivers containing backdoors, ransomware, or other malware that will be automatically deployed to endpoints through the legitimate print management workflow.

The network-accessible nature of this vulnerability means that attackers do not require any special privileges or user interaction to potentially exploit this weakness, making it particularly dangerous in environments where Vasion Print is exposed to untrusted networks.

Root Cause

The root cause stems from inadequate implementation of malware detection mechanisms within the Vasion Print application. The system's antivirus protection capabilities are insufficient to identify and block printer drivers that contain known malicious code patterns. This protection gap allows potentially dangerous drivers to pass through validation checks and be distributed to managed endpoints.

Attack Vector

The attack vector is network-based, allowing remote exploitation without authentication. An attacker could potentially upload or inject a malicious printer driver containing known malware signatures into the Vasion Print system. Due to the insufficient antivirus protection, the malicious driver would not be detected and could be distributed to all managed print clients across the organization.

The exploitation scenario involves leveraging the print management infrastructure as a malware distribution mechanism, turning a trusted enterprise tool into an attack vector for deploying malicious payloads at scale.

Detection Methods for CVE-2025-27665

Indicators of Compromise

• Unusual printer driver installations originating from the Vasion Print server
• Detection of known malware signatures within printer driver packages stored on the print management server
• Unexpected network connections or behaviors from endpoints following driver deployments
• Anomalous file creation or process execution triggered by printer driver components

Detection Strategies

• Deploy endpoint detection and response (EDR) solutions to monitor for malicious activity following driver installations
• Implement network traffic analysis to identify suspicious communications from print infrastructure
• Configure SIEM rules to correlate driver deployment events with subsequent malware detections
• Perform regular scans of the driver repository on Vasion Print servers using enterprise antivirus solutions

Monitoring Recommendations

• Monitor the Vasion Print driver repository for newly added or modified driver packages
• Implement file integrity monitoring on print server driver directories
• Track driver deployment logs for unusual patterns or bulk deployments
• Enable verbose logging on Vasion Print servers and forward logs to centralized SIEM systems

How to Mitigate CVE-2025-27665

Immediate Actions Required

• Update Vasion Print Virtual Appliance Host to version 22.0.843 or later
• Upgrade Vasion Print Application to version 20.0.1923 or later
• Audit existing printer driver repository for known malicious signatures
• Restrict network access to Vasion Print management interfaces to trusted administrative networks

Patch Information

Vasion (formerly PrinterLogic) has released security patches addressing this vulnerability. Organizations should update to Virtual Appliance Host version 22.0.843 or later and Application version 20.0.1923 or later. Detailed patch information and security bulletins are available from the PrinterLogic Security Bulletins page.

Workarounds

• Implement network segmentation to isolate print management infrastructure from untrusted networks
• Deploy additional endpoint protection on the Vasion Print server to scan driver packages before distribution
• Manually scan all printer drivers using enterprise antivirus solutions before importing into the print management system
• Restrict driver upload capabilities to verified administrator accounts only
• Consider temporarily disabling automatic driver distribution until patches can be applied

# Example: Restrict network access to print management interface
# Add firewall rules to limit access to administrative networks only
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP

# Verify driver repository permissions
chmod 750 /opt/printerlogic/drivers
chown -R printadmin:printadmin /opt/printerlogic/drivers
