CVE-2025-27643: Vasion Print Hardcoded Credentials Flaw

CVE-2025-27643 Overview

CVE-2025-27643 is a critical hardcoded credentials vulnerability affecting Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application components. The vulnerability involves a hardcoded AWS API key embedded within the application, which could allow unauthorized access to AWS resources and services associated with the PrinterLogic infrastructure.

Hardcoded credentials represent one of the most severe security misconfigurations, as they cannot be rotated without updating the affected software and expose organizations to persistent unauthorized access risks. This vulnerability is tracked as V-2024-006 by the vendor.

Critical Impact

Attackers with network access can leverage hardcoded AWS API credentials to potentially access cloud resources, exfiltrate data, or pivot to other services connected to the AWS infrastructure.

Affected Products

• Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions before 22.0.933
• Vasion Print Application versions before 20.0.2368
• PrinterLogic Virtual Appliance deployments using vulnerable versions

Technical Details for CVE-2025-27643

Vulnerability Analysis

This vulnerability falls under CWE-798 (Use of Hard-coded Credentials), a severe security weakness where authentication credentials are embedded directly in source code or configuration files. In the case of CVE-2025-27643, an AWS API key has been hardcoded into the Vasion Print application, creating a persistent security risk.

The hardcoded AWS API key could provide attackers with access to AWS services and resources configured for the PrinterLogic infrastructure. Depending on the permissions associated with this API key, exploitation could lead to unauthorized access to S3 buckets, EC2 instances, or other AWS services, potentially exposing sensitive print job data or enabling further attacks against the cloud infrastructure.

The vulnerability requires no authentication or user interaction to exploit, making it particularly dangerous in network-accessible deployments.

Root Cause

The root cause of CVE-2025-27643 is the insecure development practice of embedding static AWS API credentials directly into the application code or configuration files. This approach eliminates the ability to rotate credentials without software updates and exposes the same credentials across all installations of the affected versions.

Proper credential management should utilize environment variables, secure vaults, or instance-based IAM roles rather than hardcoded values. The presence of this vulnerability suggests inadequate security review processes during development.

Attack Vector

The attack vector for this vulnerability is network-based and requires no privileges or user interaction. An attacker who can access an affected Vasion Print installation or extract the application binaries can obtain the hardcoded AWS API key.

Once the credentials are extracted, the attacker can:

• Authenticate to AWS services using the compromised API key
• Access any AWS resources the key has permissions to interact with
• Potentially escalate access within the AWS environment
• Exfiltrate data or modify cloud-based configurations

The exploitation does not require any special conditions beyond access to the vulnerable application, either through network access to the deployment or by obtaining the application files through other means.

Detection Methods for CVE-2025-27643

Indicators of Compromise

• Unexpected API calls to AWS services from IP addresses not associated with legitimate Vasion Print infrastructure
• Authentication events using the compromised AWS API key from unusual geographic locations or at unexpected times
• Anomalous access patterns to S3 buckets or other AWS resources linked to PrinterLogic operations
• CloudTrail logs showing API activity from unknown sources using PrinterLogic-associated credentials

Detection Strategies

• Monitor AWS CloudTrail logs for API calls using credentials associated with Vasion Print deployments from unexpected sources
• Implement AWS GuardDuty to detect anomalous credential usage patterns
• Review network traffic for outbound connections to AWS endpoints from Vasion Print servers that deviate from normal baseline activity
• Deploy endpoint detection solutions to identify extraction attempts targeting application binaries or configuration files

Monitoring Recommendations

• Enable comprehensive AWS CloudTrail logging for all regions where PrinterLogic-associated resources exist
• Configure CloudWatch alarms for unusual API activity patterns or access from new IP addresses
• Implement network monitoring to track outbound connections from Vasion Print servers
• Establish baseline activity patterns for legitimate PrinterLogic AWS interactions to identify deviations

How to Mitigate CVE-2025-27643

Immediate Actions Required

• Update Vasion Print Virtual Appliance Host to version 22.0.933 or later immediately
• Update Vasion Print Application to version 20.0.2368 or later
• Contact Vasion/PrinterLogic support to determine if the compromised AWS API key has been rotated on their infrastructure
• Review AWS CloudTrail logs for any unauthorized access using credentials associated with affected deployments

Patch Information

Vasion has addressed this vulnerability in Virtual Appliance Host version 22.0.933 and Application version 20.0.2368. Organizations should upgrade to these versions or later to remediate CVE-2025-27643. Security bulletins and patch information are available through the PrinterLogic Security Bulletins page.

Additional technical analysis of this vulnerability and related issues can be found in the Pierre Kim Blog Analysis and the Full Disclosure Mailing List.

Workarounds

• Restrict network access to Vasion Print servers to only authorized administrative networks using firewall rules
• Implement network segmentation to limit the potential impact of credential compromise
• Monitor AWS API usage associated with PrinterLogic deployments until patches can be applied
• Consider temporarily isolating affected systems from internet access if immediate patching is not possible
