CVE-2025-27674
📋 TL;DR
CVE-2025-27674 is a critical vulnerability in Vasion Print (formerly PrinterLogic) that involves a hardcoded Identity Provider (IdP) key. This allows attackers to bypass authentication mechanisms and potentially gain administrative access to the system. Organizations using affected versions of Vasion Print Virtual Appliance Host and Application are at risk.
💻 Affected Systems
- Vasion Print (formerly PrinterLogic) Virtual Appliance Host
- Vasion Print Application
📦 What is this software?
Vasion Print by Printerlogic
Virtual Appliance by Printerlogic
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the Vasion Print environment, allowing attackers to deploy ransomware, exfiltrate sensitive data, or pivot to other network systems.
Likely Case
Unauthorized administrative access leading to printer configuration manipulation, deployment of malicious print drivers, or credential harvesting.
If Mitigated
Limited impact if network segmentation prevents access to vulnerable systems and strong authentication controls are in place.
🎯 Exploit Status
The hardcoded key is publicly documented in security research, making exploitation straightforward for attackers with network access.
🛠️ 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. Backup current configuration. 2. Download and install the patched version from Vasion support portal. 3. Apply the update through the appliance management interface. 4. Restart the virtual appliance. 5. Verify functionality post-update.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Vasion Print systems from untrusted networks and limit access to authorized administrative IPs only.
Access Control Lists
allImplement firewall rules to restrict access to Vasion Print management interfaces.
🧯 If You Can't Patch
- Immediately isolate affected systems from internet access and untrusted network segments.
- Implement multi-factor authentication for all administrative access and monitor for unauthorized authentication attempts.
🔍 How to Verify
Check if Vulnerable:
Check the Virtual Appliance Host version in the web administration interface under System > About. If version is below 22.0.843, the system is vulnerable.
Check Version:
Connect to the appliance web interface and navigate to System > About to view version information.
Verify Fix Applied:
After patching, verify the version shows 22.0.843 or higher in the administration interface and test authentication functionality.
📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts from unexpected IP addresses
- Administrative actions from non-standard user accounts
- Failed authentication followed by successful authentication using default credentials
Network Indicators:
- Unexpected connections to Vasion Print management ports (typically 443/HTTPS)
- Traffic patterns indicating brute force attempts against authentication endpoints
