CVE-2025-27664: Printerlogic Vasion Print CSRF Vulnerability

CVE-2025-27664 Overview

CVE-2025-27664 is a Cross-Site Request Forgery (CSRF) vulnerability affecting Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 22.0.843 and Application 20.0.1923. The vulnerability stems from insufficient CSRF protection mechanisms within the application, allowing attackers to potentially execute unauthorized actions on behalf of authenticated users.

Critical Impact

Attackers can exploit insufficient CSRF protections to trick authenticated users into performing unintended actions, potentially leading to unauthorized configuration changes, data manipulation, or compromise of print management infrastructure.

Affected Products

• Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions before 22.0.843
• Vasion Print Application versions before 20.0.1923
• PrinterLogic Virtual Appliance (all versions prior to the patched release)

Technical Details for CVE-2025-27664

Vulnerability Analysis

This vulnerability is classified under CWE-352 (Cross-Site Request Forgery). CSRF vulnerabilities occur when a web application fails to adequately verify that requests originate from legitimate user interactions. In the context of Vasion Print, the application does not implement sufficient anti-CSRF tokens or validation mechanisms, enabling attackers to craft malicious requests that execute privileged operations when an authenticated administrator visits an attacker-controlled page.

The vulnerability is particularly concerning for enterprise print management solutions like Vasion Print, which often operate with elevated privileges within corporate networks and manage sensitive printing infrastructure. Successful exploitation requires user interaction—specifically, an authenticated user must be tricked into visiting a malicious webpage or clicking a crafted link while maintaining an active session.

Root Cause

The root cause of CVE-2025-27664 lies in the absence or improper implementation of CSRF protection mechanisms within the Vasion Print web interface. The application fails to validate the origin of state-changing requests, allowing forged requests from external sources to be processed as legitimate user actions. This oversight enables attackers to construct malicious forms or scripts that, when executed in the context of an authenticated session, perform unauthorized operations on the print management system.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication from the attacker's perspective. The attack sequence typically follows this pattern:

1. The attacker identifies state-changing endpoints in the Vasion Print application that lack proper CSRF validation
2. A malicious webpage or email is crafted containing hidden forms or JavaScript that target these vulnerable endpoints
3. An authenticated Vasion Print administrator is socially engineered to visit the attacker's page while logged into the management console
4. The victim's browser automatically sends the forged request along with valid session cookies
5. The Vasion Print server processes the request as legitimate, executing the attacker's intended action

Common exploitation scenarios include modifying printer configurations, adding malicious print drivers, changing user permissions, or altering system settings within the print management infrastructure.

Detection Methods for CVE-2025-27664

Indicators of Compromise

• Unexpected configuration changes to printer settings or user permissions without corresponding administrative activity logs
• HTTP requests to Vasion Print administrative endpoints originating from external referrers or missing expected anti-CSRF tokens
• Unusual administrative actions occurring during off-hours or from IP addresses not associated with legitimate administrators
• Multiple state-changing requests executed in rapid succession from a single user session

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block requests lacking proper CSRF tokens or with suspicious referrer headers
• Monitor Vasion Print access logs for administrative actions that correlate with external browsing activity
• Deploy network monitoring to identify unusual traffic patterns to the Vasion Print management interface
• Utilize SentinelOne's behavioral AI to detect anomalous web application interactions and potential exploitation attempts

Monitoring Recommendations

• Enable comprehensive audit logging within Vasion Print to track all administrative actions and configuration changes
• Configure alerts for administrative operations performed without corresponding user-initiated workflow triggers
• Establish baseline behavior patterns for Vasion Print administrative interfaces to detect deviations indicative of CSRF attacks
• Review web server logs for requests with missing or invalid Origin and Referer headers targeting sensitive endpoints

How to Mitigate CVE-2025-27664

Immediate Actions Required

• Upgrade Vasion Print Virtual Appliance Host to version 22.0.843 or later immediately
• Upgrade Vasion Print Application to version 20.0.1923 or later
• Restrict network access to Vasion Print administrative interfaces to trusted IP ranges
• Implement additional authentication requirements for sensitive administrative operations until patching is complete

Patch Information

Vasion (formerly PrinterLogic) has released patched versions addressing this CSRF vulnerability. Organizations should update to Virtual Appliance Host version 22.0.843 or later and Application version 20.0.1923 or later. For detailed patch information and installation guidance, refer to the PrinterLogic Security Bulletins.

Workarounds

• Implement network segmentation to isolate Vasion Print management interfaces from general user networks
• Configure web browser policies for administrators to prevent automatic credential submission to external sites
• Deploy a reverse proxy with CSRF validation capabilities in front of the Vasion Print interface
• Educate administrators about phishing and social engineering risks, emphasizing the importance of not clicking untrusted links while authenticated to management consoles
• Consider temporarily disabling remote administrative access until patches can be applied

# Example: Restrict administrative interface access using iptables
# Allow access only from trusted administrator subnet
iptables -A INPUT -p tcp --dport 443 -s 10.0.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
