CVE-2025-27657: Vasion Print RCE Vulnerability

CVE-2025-27657 Overview

CVE-2025-27657 is a Remote Code Execution (RCE) vulnerability affecting Vasion Print, formerly known as PrinterLogic. This vulnerability exists in versions prior to Virtual Appliance Host 22.0.843 and Application 20.0.1923. The flaw allows unauthenticated remote attackers to execute arbitrary code on vulnerable systems, potentially leading to complete system compromise.

Vasion Print is an enterprise print management solution widely deployed in corporate environments to manage printer deployments, driver installations, and print policies across large networks. The ability to execute arbitrary code remotely without authentication makes this vulnerability particularly dangerous for organizations relying on this platform.

Critical Impact

Unauthenticated remote attackers can achieve arbitrary code execution on vulnerable Vasion Print deployments, potentially compromising enterprise print infrastructure and pivoting to other network resources.

Affected Products

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

Technical Details for CVE-2025-27657

Vulnerability Analysis

This vulnerability is classified under CWE-94 (Improper Control of Generation of Code, also known as Code Injection). The flaw enables attackers to inject and execute malicious code on the target system through the network without requiring any authentication or user interaction.

The vulnerability was identified as part of a broader security audit that discovered multiple vulnerabilities in the Vasion Print platform. The Remote Code Execution capability provides attackers with the highest level of access to compromised systems, allowing them to execute arbitrary commands with the privileges of the application.

Enterprise print management systems like Vasion Print often operate with elevated privileges to install printer drivers and manage system configurations, making successful exploitation particularly impactful. Compromised systems could serve as pivot points for lateral movement within corporate networks.

Root Cause

The root cause of CVE-2025-27657 stems from improper control of code generation (CWE-94). The application fails to properly sanitize or validate input before it is used in code execution contexts. This allows attacker-controlled data to be interpreted and executed as code by the application.

Code injection vulnerabilities typically arise when applications dynamically generate or execute code based on external input without adequate security controls. In enterprise software like print management systems, these vulnerabilities can be introduced through web interfaces, API endpoints, or inter-component communication channels.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker with network access to the vulnerable Vasion Print deployment can exploit this flaw remotely. The vulnerability is classified as having low attack complexity, meaning exploitation does not require specialized conditions or extensive preparation.

The vulnerability mechanism involves injecting malicious code through the application's input handling pathways. Due to the nature of code injection vulnerabilities, successful exploitation allows attackers to execute arbitrary system commands, install malware, exfiltrate data, or establish persistent backdoor access to the compromised system.

Detection Methods for CVE-2025-27657

Indicators of Compromise

• Unexpected outbound network connections from Vasion Print servers to unknown external IP addresses
• Anomalous process creation or command execution originating from Vasion Print application processes
• Unusual file system modifications in Vasion Print installation directories
• Authentication logs showing unauthorized access attempts or successful logins from unexpected sources
• New or modified scheduled tasks or services associated with the print management infrastructure

Detection Strategies

• Deploy network intrusion detection systems (IDS) to monitor traffic to and from Vasion Print servers for suspicious patterns
• Implement application-level logging to capture and analyze requests to the print management platform
• Configure endpoint detection and response (EDR) solutions to monitor for code injection indicators on systems running Vasion Print
• Establish baseline behavior for Vasion Print processes and alert on deviations

Monitoring Recommendations

• Enable comprehensive audit logging on all Vasion Print Virtual Appliance hosts
• Monitor for unusual process spawning or command execution from web application contexts
• Review network flow data for connections to known malicious infrastructure
• Implement file integrity monitoring on critical Vasion Print configuration and binary files

How to Mitigate CVE-2025-27657

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 management interfaces to trusted administrative networks only
• Implement network segmentation to isolate print management infrastructure from critical assets
• Conduct a security review of systems that may have been exposed while running vulnerable versions

Patch Information

Vasion (formerly PrinterLogic) has released patched versions addressing this vulnerability. Organizations should upgrade to Virtual Appliance Host version 22.0.843 or later and Application version 20.0.1923 or later to remediate this issue.

For official patch information and security guidance, consult the PrinterLogic Security Bulletins page.

Workarounds

• Implement strict network access controls to limit exposure of Vasion Print services to only authorized networks
• Deploy a web application firewall (WAF) in front of Vasion Print interfaces to filter potentially malicious requests
• Disable unnecessary services and features on Vasion Print deployments to reduce attack surface
• Monitor systems for exploitation attempts while planning and executing the upgrade process

# Example: Restrict network access to Vasion Print management interface
# Using iptables to limit access to trusted administrative subnet only
iptables -A INPUT -p tcp --dport 443 -s 10.0.100.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
