Description
Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.2.169 and Application prior to version 25.2.1518 (VA/SaaS deployments) expose every internal Docker container to the network because firewall rules allow unrestricted traffic to the Docker bridge network. Because no authentication, ACL or client‑side identifier is required, the attacker can interact with any internal API, bypassing the product’s authentication mechanisms entirely. The result is unauthenticated remote access to internal services, allowing credential theft, configuration manipulation and potential remote code execution. This vulnerability has been identified by the vendor as: V-2025-002 — Authentication Bypass - Docker Instances.

Comprehensive Technical Analysis of EUVD-2025-31624
1. Vulnerability Assessment and Severity Evaluation
Vulnerability Description: The vulnerability in Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application allows unrestricted network access to internal Docker containers due to inadequate firewall rules. This exposure enables attackers to bypass authentication mechanisms and interact with internal APIs, leading to unauthenticated remote access to internal services.
Severity Evaluation:
- Base Score: 10.0 (Critical)
- Base Score Version: 4.0
- Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
The CVSS score of 10.0 indicates a critical vulnerability with high potential for exploitation. The vector string highlights that the vulnerability can be exploited remotely (AV:N), requires low complexity (AC:L), does not need user interaction (UI:N), and has high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:H).
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network Access: Attackers can exploit this vulnerability by gaining network access to the Docker bridge network, which is exposed due to lax firewall rules.
- API Interaction: Without authentication, ACL, or client-side identifiers, attackers can interact with internal APIs, bypassing the product’s authentication mechanisms.
Exploitation Methods:
- Credential Theft: Attackers can steal credentials by accessing internal services.
- Configuration Manipulation: Unauthorized access allows attackers to manipulate configurations, potentially leading to further compromise.
- Remote Code Execution: The vulnerability could enable attackers to execute arbitrary code on the affected systems.
3. Affected Systems and Software Versions
Affected Systems:
- Vasion Print Virtual Appliance Host: Versions prior to 25.2.169
- Vasion Print Application: Versions prior to 25.2.1518
Deployment Types:
- VA (Virtual Appliance) Deployments
- SaaS (Software as a Service) Deployments
4. Recommended Mitigation Strategies
Immediate Actions:
- Update Software: Upgrade to Vasion Print Virtual Appliance Host version 25.2.169 or later and Vasion Print Application version 25.2.1518 or later.
- Firewall Configuration: Implement strict firewall rules to restrict access to the Docker bridge network.
- Authentication Mechanisms: Ensure that all internal APIs require proper authentication and access controls.
Long-Term Strategies:
- Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
- Network Segmentation: Implement network segmentation to limit the exposure of internal services.
- Monitoring: Deploy monitoring tools to detect and respond to unauthorized access attempts.
5. Impact on European Cybersecurity Landscape
Regulatory Compliance:
- GDPR: Unauthorized access to internal services can lead to data breaches, violating GDPR regulations and resulting in significant fines.
- NIS Directive: Organizations in critical sectors must ensure robust cybersecurity measures to comply with the NIS Directive.
Operational Impact:
- Service Disruption: Exploitation of this vulnerability can lead to service disruptions, affecting business continuity.
- Reputation Damage: Data breaches and unauthorized access can result in reputational damage and loss of customer trust.
