CVE-2025-27674

9.8 CRITICAL

📋 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

Products:
  • Vasion Print (formerly PrinterLogic) Virtual Appliance Host
  • Vasion Print Application
Versions: Virtual Appliance Host versions before 22.0.843, Application versions before 20.0.1923
Operating Systems: Linux (appliance-based deployment)
Default Config Vulnerable: ⚠️ Yes
Notes: Affects both on-premises virtual appliance deployments and potentially cloud-hosted instances.

📦 What is this software?

⚠️ 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.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

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

all

Isolate Vasion Print systems from untrusted networks and limit access to authorized administrative IPs only.

Access Control Lists

all

Implement 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

SIEM Query:

source="vasion-print" AND (event_type="authentication" AND result="success" AND user="*") | stats count by src_ip, user
