CVE-2025-27669
📋 TL;DR
This vulnerability in Vasion Print (formerly PrinterLogic) allows remote attackers to perform network scanning and cause denial-of-service conditions. Organizations using affected versions of the Virtual Appliance Host and Application are vulnerable to these attacks.
💻 Affected Systems
- Vasion Print Virtual Appliance Host
- Vasion Print Application
📦 What is this software?
Vasion Print by Printerlogic
Virtual Appliance by Printerlogic
⚠️ Risk & Real-World Impact
Worst Case
Attackers could map internal networks, identify other vulnerable systems, and cause complete service disruption of printing infrastructure.
Likely Case
Network reconnaissance leading to targeted attacks on other systems, combined with intermittent printing service outages.
If Mitigated
Limited network visibility and temporary service degradation rather than complete outage.
🎯 Exploit Status
Exploitation requires network access but no authentication. The CWE-400 (Uncontrolled Resource Consumption) suggests resource exhaustion techniques.
🛠️ 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: No
Instructions:
1. Log into Vasion Print admin console. 2. Navigate to System Updates. 3. Apply available updates for Virtual Appliance Host and Application. 4. Verify both components show updated versions.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Vasion Print servers from sensitive network segments to limit scanning impact
Rate Limiting
allImplement network-level rate limiting on Vasion Print server interfaces
🧯 If You Can't Patch
- Implement strict network access controls to limit which systems can communicate with Vasion Print servers
- Deploy intrusion detection systems to monitor for scanning patterns and DoS attempts against printing infrastructure
🔍 How to Verify
Check if Vulnerable:
Check Vasion Print admin console for current versions of Virtual Appliance Host and Application componentsCheck Version:
Check via Vasion Print admin interface under System Information or via API if availableVerify Fix Applied:
Confirm Virtual Appliance Host version is 22.0.843 or higher AND Application version is 20.0.1923 or higher📡 Detection & Monitoring
