CVE-2025-34234
📋 TL;DR
Vasion Print (formerly PrinterLogic) contains hardcoded encryption keys in its application containers, allowing attackers who can access the filesystem to decrypt sensitive SaaS identifiers. This affects Virtual Appliance Host versions before 25.1.102 and Application versions before 25.1.1413 in VA/SaaS deployments. The vulnerability enables decryption of encrypted external identifiers used by the system.
💻 Affected Systems
- Vasion Print Virtual Appliance Host
- Vasion Print Application
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers decrypt all SaaS identifiers, potentially enabling unauthorized access to external systems, data exfiltration, or lateral movement within connected environments.
Likely Case
Attackers with filesystem access decrypt SaaS identifiers to map infrastructure relationships or prepare for further attacks on connected systems.
If Mitigated
With proper access controls, impact is limited to information disclosure about system identifiers without direct system compromise.
🎯 Exploit Status
Exploitation requires filesystem access to read the hardcoded keys, which typically requires some level of system access or container escape
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Virtual Appliance Host 25.1.102+, Application 25.1.1413+
Vendor Advisory: https://help.printerlogic.com/saas/Print/Security/Security-Bulletins.htm
Restart Required: Yes
Instructions:
1. Update to Virtual Appliance Host version 25.1.102 or later
2. Update to Application version 25.1.1413 or later
3. Restart affected containers
4. Verify keys are no longer present in /var/www/app/config/
🔧 Temporary Workarounds
Remove hardcoded keys manually
linuxManually delete the hardcoded key files from the filesystem
rm -f /var/www/app/config/keyfile.ppk.dev
rm -f /var/www/app/config/keyfile.saasid.ppk.dev
Restrict filesystem access
linuxImplement strict filesystem permissions to prevent unauthorized access to configuration directories
chmod 600 /var/www/app/config/*
chown root:root /var/www/app/config/*
🧯 If You Can't Patch
- Implement strict access controls to prevent unauthorized filesystem access to containers
- Monitor for unauthorized access attempts to configuration directories and key files
🔍 How to Verify
Check if Vulnerable:
Check if key files exist: ls -la /var/www/app/config/keyfile*.ppk.devCheck Version:
Check container version through application interface or docker inspectVerify Fix Applied:
Verify key files are removed and check application version meets patched requirements📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to /var/www/app/config/ directory
- File read operations on keyfile.ppk.dev or keyfile.saasid.ppk.dev
Network Indicators:
- Unusual outbound connections following configuration file access
