CVE-2025-27667
📋 TL;DR
This vulnerability allows attackers to enumerate administrative user email addresses in Vasion Print (formerly PrinterLogic) systems. Attackers can identify valid administrator accounts, which could facilitate targeted phishing or credential attacks. Organizations using affected versions of Vasion Print Virtual Appliance Host and Application are impacted.
💻 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 obtain administrator email addresses, conduct targeted phishing campaigns to steal credentials, gain administrative access to the print management system, and potentially pivot to other systems in the network.
Likely Case
Attackers enumerate administrator emails and use them for targeted phishing or credential stuffing attacks against the organization's administrators.
If Mitigated
With proper network segmentation and access controls, attackers can only enumerate emails but cannot progress to system compromise without additional vulnerabilities.
🎯 Exploit Status
Email enumeration vulnerabilities typically require minimal technical skill to exploit once the attack vector is understood.
🛠️ 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 Virtual Appliance Host 22.0.843+ and Application 20.0.1923+ from vendor portal. 3. Apply patches following vendor documentation. 4. Restart services/reboot appliance. 5. Verify functionality.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to Vasion Print administrative interfaces to trusted IP addresses only
# Configure firewall rules to allow only specific IPs to access administrative ports
# Example: iptables -A INPUT -p tcp --dport [admin_port] -s [trusted_ip] -j ACCEPT
# iptables -A INPUT -p tcp --dport [admin_port] -j DROP
Rate Limiting
linuxImplement rate limiting on authentication endpoints to prevent enumeration attempts
# Use web server or application firewall to limit requests per IP
# Example nginx: limit_req_zone $binary_remote_addr zone=auth:10m rate=10r/m;
# Then apply to location blocks for auth endpoints
🧯 If You Can't Patch
- Isolate Vasion Print systems on separate network segments with strict firewall rules
- Implement multi-factor authentication for all administrative accounts to mitigate credential theft risk
🔍 How to Verify
Check if Vulnerable:
Check current version in Vasion Print administrative interface under System Information or SettingsCheck Version:
# SSH to appliance and check version: cat /opt/printerlogic/version.txt || grep -i version /opt/printerlogic/*.propertiesVerify Fix Applied:
Confirm version shows Virtual Appliance Host 22.0.843+ and Application 20.0.1923+ in administrative interface📡 Detection & Monitoring
Log Indicators:
- Unusual patterns of failed authentication attempts
- Multiple requests to user enumeration endpoints from single IPs
- Access to administrative interfaces from unexpected IP addresses
Network Indicators:
- High volume of requests to authentication/email-related endpoints
- Traffic to Vasion Print administrative ports from external/untrusted sources
