CVE-2025-27670
📋 TL;DR
CVE-2025-27670 is a critical vulnerability in Vasion Print (formerly PrinterLogic) that allows attackers to bypass signature validation mechanisms. This could enable remote code execution or privilege escalation on affected systems. Organizations using Vasion Print Virtual Appliance Host before version 22.0.843 and Application before version 20.0.1923 are at risk.
💻 Affected Systems
- Vasion Print (formerly PrinterLogic) Virtual Appliance Host
- Vasion Print Application

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code with highest privileges, potentially leading to data theft, ransomware deployment, or lateral movement across the network.
Likely Case
Privilege escalation leading to unauthorized access to sensitive print management functions, configuration manipulation, or installation of malicious print drivers.
If Mitigated
Limited impact if proper network segmentation, least privilege access controls, and intrusion detection systems are in place to contain potential exploitation.
🎯 Exploit Status
The high CVSS score and nature of insufficient signature validation suggests exploitation is relatively straightforward once the vulnerability details are understood.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Virtual Appliance Host 22.0.843 or later, Application 20.0.1923 or later
Vendor Advisory: https://help.printerlogic.com/saas/Print/Security/Security-Bulletins.htm
Restart Required: Yes
Instructions:
1. Download the latest patches from the Vasion support portal. 2. Backup current configuration. 3. Apply Virtual Appliance Host update to version 22.0.843+. 4. Apply Application update to version 20.0.1923+. 5. Restart services. 6. Verify functionality.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Vasion Print systems from internet access and restrict internal network access to authorized users only.
Access Control Hardening
allImplement strict access controls and multi-factor authentication for administrative interfaces.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable systems from critical assets
- Deploy intrusion detection systems to monitor for exploitation attempts and anomalous behavior
🔍 How to Verify
Check if Vulnerable:
Check the Virtual Appliance Host version via web interface or SSH: cat /etc/printerlogic/version. Check Application version via admin console.Check Version:
Virtual Appliance: cat /etc/printerlogic/version || dpkg -l | grep printerlogic. Application: Check admin console or registry: HKEY_LOCAL_MACHINE\SOFTWARE\PrinterLogic\VersionVerify Fix Applied:
Verify version numbers: Virtual Appliance Host should be 22.0.843+, Application should be 20.0.1923+. Test signature validation functionality.📡 Detection & Monitoring
Log Indicators:
- Failed signature validation attempts
- Unexpected process execution from print services
- Unauthorized configuration changes to print settings
Network Indicators:
- Unusual outbound connections from print servers
- Anomalous traffic patterns to/from print management ports
