CVE-2025-27655
📋 TL;DR
This CVE describes a Server-Side Request Forgery (SSRF) vulnerability in Vasion Print (formerly PrinterLogic) that allows attackers to make unauthorized requests from the vulnerable server. The vulnerability affects Virtual Appliance Host versions before 22.0.862 and Application versions before 20.0.2014. Attackers could potentially access internal systems or services that should not be externally accessible.
💻 Affected Systems
- Vasion Print
- PrinterLogic
📦 What is this software?
Vasion Print by Printerlogic
Virtual Appliance by Printerlogic
⚠️ Risk & Real-World Impact
Worst Case
Attackers could pivot from the vulnerable server to access internal systems, steal sensitive data, or perform lateral movement within the network, potentially leading to full network compromise.
Likely Case
Attackers exploit the SSRF to access internal services, scan internal networks, or interact with cloud metadata services to obtain credentials and escalate privileges.
If Mitigated
With proper network segmentation and access controls, the impact is limited to the vulnerable server itself, preventing lateral movement to other systems.
🎯 Exploit Status
The vulnerability is part of a larger disclosure of 83 vulnerabilities in Vasion Print products, suggesting active research and potential exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Virtual Appliance Host 22.0.862 or later, Application 20.0.2014 or later
Vendor Advisory: https://help.printerlogic.com/saas/Print/Security/Security-Bulletins.htm
Restart Required: Yes
Instructions:
1. Download the latest version from the vendor portal. 2. Backup current configuration. 3. Apply the update following vendor instructions. 4. Restart the virtual appliance. 5. Verify the update was successful.
🔧 Temporary Workarounds
Network Segmentation
allRestrict outbound network access from the Vasion Print server to only necessary services
Access Control Lists
allImplement firewall rules to block the vulnerable server from accessing internal services
🧯 If You Can't Patch
- Isolate the Vasion Print server in a dedicated network segment with strict egress filtering
- Implement web application firewall (WAF) rules to detect and block SSRF patterns
🔍 How to Verify
Check if Vulnerable:
Check the Virtual Appliance Host version in the admin interface or via SSH: cat /etc/printerlogic/versionCheck Version:
ssh admin@vasion-print-server 'cat /etc/printerlogic/version'Verify Fix Applied:
Verify the version is 22.0.862 or higher for Virtual Appliance Host, and 20.0.2014 or higher for Application📡 Detection & Monitoring
