CVE-2025-27640: Vasion Print SQL Injection Vulnerability

CVE-2025-27640 Overview

CVE-2025-27640 is a critical SQL Injection vulnerability affecting Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application components. This vulnerability allows unauthenticated remote attackers to inject malicious SQL queries through the application's network-accessible interfaces, potentially leading to unauthorized data access, modification, or complete database compromise.

The vulnerability, tracked internally by the vendor as V-2024-012, exists in versions prior to Virtual Appliance Host 22.0.1002 and Application 20.0.2614. SQL Injection flaws of this nature are classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability remotely to access, modify, or delete sensitive data stored in the PrinterLogic database, potentially compromising the entire print management infrastructure.

Affected Products

• Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions before 22.0.1002
• Vasion Print Application versions before 20.0.2614
• PrinterLogic Virtual Appliance (all versions prior to the patched releases)

Technical Details for CVE-2025-27640

Vulnerability Analysis

This SQL Injection vulnerability affects the Vasion Print enterprise print management solution. The flaw exists due to improper neutralization of user-supplied input before it is included in SQL queries executed by the application backend. Attackers can craft malicious input containing SQL syntax that, when processed by the vulnerable application, alters the intended query logic.

Since the vulnerability requires no authentication and is accessible over the network, it presents a significant risk to organizations running vulnerable versions of the PrinterLogic/Vasion Print software. Successful exploitation could allow attackers to extract sensitive configuration data, enumerate user credentials, modify print job records, or potentially achieve further system compromise through database-level access.

Root Cause

The root cause of CVE-2025-27640 is insufficient input validation and lack of parameterized queries in the affected Vasion Print components. User-controllable data is concatenated directly into SQL statements without proper sanitization or use of prepared statements, allowing malicious SQL fragments to be interpreted and executed by the database engine.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no privileges or user interaction. An attacker with network access to the Vasion Print Virtual Appliance can send specially crafted requests containing SQL injection payloads to vulnerable endpoints. The application processes these inputs without adequate sanitization, allowing the injected SQL code to execute against the backend database.

Due to the nature of SQL Injection, exploitation could enable attackers to:

• Bypass authentication mechanisms
• Extract sensitive data including credentials and configuration information
• Modify or delete database records
• Potentially achieve remote code execution through database features (depending on database configuration)

No verified proof-of-concept code is publicly available for this vulnerability. For technical details on the vulnerability mechanism, refer to the PrinterLogic Security Bulletins.

Detection Methods for CVE-2025-27640

Indicators of Compromise

• Unusual SQL error messages appearing in application or web server logs
• Database queries containing unexpected characters such as single quotes, semicolons, or SQL keywords like UNION, SELECT, DROP
• Abnormal database query patterns or execution times indicating data exfiltration attempts
• Unexpected outbound connections from the database server

Detection Strategies

• Monitor web application logs for patterns indicative of SQL injection attempts, including URL-encoded special characters and SQL syntax
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
• Deploy web application firewall (WAF) rules to identify and block common SQL injection payloads
• Enable detailed logging on the Vasion Print application to capture request parameters for forensic analysis

Monitoring Recommendations

• Configure SIEM alerts for SQL injection attack signatures targeting PrinterLogic/Vasion Print endpoints
• Monitor database audit logs for queries executed with unexpected privileges or accessing sensitive tables
• Track failed authentication attempts that may indicate post-exploitation activity
• Establish baseline behavior for database queries and alert on deviations

How to Mitigate CVE-2025-27640

Immediate Actions Required

• Upgrade Vasion Print Virtual Appliance Host to version 22.0.1002 or later immediately
• Upgrade Vasion Print Application to version 20.0.2614 or later
• Review database logs for evidence of exploitation attempts prior to patching
• Consider network segmentation to limit exposure of the PrinterLogic/Vasion Print application

Patch Information

Vasion (formerly PrinterLogic) has released security updates addressing this SQL Injection vulnerability. Organizations should upgrade to Virtual Appliance Host version 22.0.1002 and Application version 20.0.2614 or later. Detailed patch information and security bulletins are available at the PrinterLogic Security Bulletins page.

Workarounds

• Restrict network access to the Vasion Print Virtual Appliance to trusted IP ranges only
• Implement a web application firewall (WAF) with SQL injection detection rules as an additional defense layer
• Place the PrinterLogic/Vasion Print server behind a VPN or in a segmented network zone
• Monitor and limit database account privileges used by the application to reduce potential impact of exploitation

# Example network restriction using iptables
# Restrict access to PrinterLogic/Vasion Print to trusted admin subnet only
iptables -A INPUT -p tcp --dport 443 -s 10.0.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
