EUVD-2025-31642

Comprehensive Technical Analysis of EUVD-2025-31642

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application involves the presence of two hardcoded private keys stored in clear text within the application containers. These keys are used for AES-256-CBC encryption/decryption of the "SaaS Id" (external identifier). The keys are located in the configuration files under /var/www/app/config/ as keyfile.ppk.dev and keyfile.saasid.ppk.dev.

Severity Evaluation: The Base Score of 9.2 (CVSS:4.0) indicates a critical vulnerability. The scoring vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N highlights the following:

• Attack Vector (AV:N): Network-based attack.
• Attack Complexity (AC:L): Low complexity required to exploit.
• Privileges Required (PR:N): No privileges are required.
• User Interaction (UI:N): No user interaction is needed.
• Confidentiality Impact (VC:H): High confidentiality impact.
• Scope Change (SC:H): The vulnerability affects a different security scope.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Docker Image Access: An attacker could obtain a copy of the Docker image and extract the hardcoded keys.
2. Configuration File Access: If an attacker gains access to the filesystem, they can read the configuration files directly.
3. Network Traffic Interception: Although less likely, intercepting network traffic could reveal the encrypted "SaaS Id," which can be decrypted using the hardcoded keys.

Exploitation Methods:

1. Key Extraction: By obtaining the Docker image or accessing the filesystem, an attacker can extract the hardcoded keys.
2. Decryption of Sensitive Data: Using the extracted keys, an attacker can decrypt any intercepted "SaaS Id" data.
3. Unauthorized Access: Decrypted "SaaS Id" data could be used to gain unauthorized access to other systems or services.

3. Affected Systems and Software Versions

Affected Systems:

• Vasion Print Virtual Appliance Host versions prior to 25.1.102.
• Vasion Print Application versions prior to 25.1.1413.

Deployment Types:

• Virtual Appliance (VA)
• Software as a Service (SaaS)

4. Recommended Mitigation Strategies

Immediate Actions:

1. Patch Deployment: Upgrade to the latest versions of the Vasion Print Virtual Appliance Host (25.1.102 or later) and Application (25.1.1413 or later).
2. Key Rotation: Implement a key rotation policy to ensure that hardcoded keys are regularly updated and not reused.
3. Access Control: Restrict access to the Docker images and configuration files to authorized personnel only.
4. Monitoring: Implement continuous monitoring for unauthorized access attempts and anomalous activities.

Long-Term Strategies:

1. Secure Key Management: Use a secure key management system to store and manage encryption keys.
2. Code Review: Conduct thorough code reviews to identify and remove hardcoded keys and other sensitive information.
3. Regular Audits: Perform regular security audits to ensure compliance with best practices and identify potential vulnerabilities.

5. Impact on European Cybersecurity Landscape

Regulatory Compliance:

• GDPR: The vulnerability could lead to unauthorized access to personal data, violating GDPR regulations.
• NIS Directive: Organizations in critical sectors must ensure robust cybersecurity measures, and this vulnerability could impact compliance.

Industry Impact:

• Printing and Document Management: Organizations relying on Vasion Print for printing and document management could face data breaches and service disruptions.
• Supply Chain: The vulnerability could affect the supply chain, impacting partners and customers who use Vasion Print services.

6. Technical Details for Security Professionals

Key Storage Location:

• /var/www/app/config/keyfile.ppk.dev
• /var/www/app/config/keyfile.saasid.ppk.dev
