CVE-2025-27664: Vasion Print CSRF Vulnerability

CVE-2025-27664 Overview

CVE-2025-27664 is a Cross-Site Request Forgery (CSRF) vulnerability in Vasion Print, formerly known as PrinterLogic. The flaw affects Virtual Appliance Host versions before 22.0.843 and Application versions before 20.0.1923. The issue is tracked internally as OVE-20230524-0008 and maps to CWE-352. An attacker who tricks an authenticated user into visiting a malicious page can force the browser to issue state-changing requests against the print management appliance. Successful exploitation can compromise confidentiality, integrity, and availability of the print infrastructure.

Critical Impact
Authenticated administrators visiting attacker-controlled content can have requests forged against the Vasion Print appliance, enabling unauthorized configuration changes across the print environment.

Affected Products

Vasion Print (formerly PrinterLogic) Virtual Appliance Host before 22.0.843
Vasion Print (formerly PrinterLogic) Application before 20.0.1923
PrinterLogic Virtual Appliance deployments running affected versions

Technical Details for CVE-2025-27664

Vulnerability Analysis

The vulnerability stems from insufficient CSRF protection on state-changing endpoints in the Vasion Print web application. CSRF defenses such as anti-forgery tokens, SameSite cookie attributes, or origin validation are missing or improperly enforced. An attacker who hosts crafted HTML or JavaScript can cause an authenticated victim's browser to submit requests using the victim's session cookies. The server processes these forged requests as legitimate administrative actions. Because the appliance manages enterprise printing services, forged requests can alter printer assignments, modify driver deployments, or change appliance configuration. Network-based attackers require user interaction, typically a click on a malicious link.

Root Cause

The root cause is missing or improperly implemented anti-CSRF controls on authenticated endpoints. The application relies on session cookies for authorization without verifying that requests originated from a legitimate first-party context. Without per-request tokens or strict origin and referer checks, the server cannot distinguish forged cross-site requests from genuine user actions.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker hosts a malicious page containing an auto-submitting form or fetch request that targets the Vasion Print management interface. When an authenticated administrator visits the page, the browser attaches valid session credentials to the forged request. The appliance executes the action under the administrator's privileges. The attacker does not need credentials or prior access, and exploitation does not require elevated privileges on the target system. Common delivery methods include phishing emails, malicious advertisements, and watering-hole attacks targeting print administrators.

No public proof-of-concept code is currently available. Refer to the PrinterLogic Security Bulletins for vendor-provided technical detail.

Detection Methods for CVE-2025-27664

Indicators of Compromise

Unexpected configuration changes in the Vasion Print management console, including new printer deployments, driver changes, or modified access policies
Web server access logs showing administrative POST requests with external Referer or Origin headers
Administrator session activity originating from unusual times or correlating with phishing email delivery
New or modified user accounts and permission changes that lack a corresponding change ticket

Detection Strategies

Inspect application access logs for state-changing requests where the Referer or Origin header does not match the Vasion Print appliance hostname
Compare appliance configuration snapshots over time to surface unauthorized modifications
Correlate administrator browser activity with email gateway telemetry for phishing indicators preceding configuration changes
Hunt for sessions that perform sensitive actions immediately after navigating from external domains

Monitoring Recommendations

Forward Vasion Print appliance logs to a centralized SIEM for retention and correlation with endpoint and email telemetry
Alert on administrative actions occurring outside maintenance windows or from unexpected user agents
Monitor egress web traffic from administrator workstations for connections to newly registered or low-reputation domains

How to Mitigate CVE-2025-27664

Immediate Actions Required

Upgrade Virtual Appliance Host to version 22.0.843 or later and Application to version 20.0.1923 or later
Restrict access to the Vasion Print management interface to administrative network segments and VPN users
Require administrators to use a dedicated browser profile or privileged access workstation when managing the appliance
Review recent appliance configuration changes and administrator audit logs for unauthorized activity

Patch Information

Vasion has released fixed builds addressing OVE-20230524-0008. Apply Virtual Appliance Host 22.0.843 and Application 20.0.1923 or newer. See the PrinterLogic Security Bulletins for release notes and upgrade guidance.

Workarounds

Limit administrator sessions to short durations and enforce logout after configuration tasks to reduce the CSRF exploitation window
Deploy browser-level protections including strict SameSite cookie enforcement and disable third-party cookies for the appliance domain
Block access to the management interface from untrusted networks using firewall rules or reverse proxy access lists
Train print administrators to avoid clicking external links while authenticated to the Vasion Print console

bash

# Example: restrict Vasion Print management interface to an admin subnet using iptables
iptables -A INPUT -p tcp --dport 443 -s 10.10.50.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
