CVE-2025-27682
CVE-2025-27682: Vasion Print (formerly PrinterLogic) Insecure Log Permissions
This document outlines the remediation and mitigation strategy for CVE-2025-27682, an Insecure Log Permissions vulnerability in Vasion Print (formerly PrinterLogic).
1. Vulnerability Description:
Vasion Print (formerly PrinterLogic) before Virtual Appliance Host 1.0.735 Application 20.0.1330 suffers from an Insecure Log Permissions vulnerability (V-2022-005). This means that the log files generated by the application are configured with overly permissive access rights, potentially allowing unauthorized users to read sensitive information.
2. Severity:
- CVSS Score: 9.8 (Critical)
- Vector: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (Network, Low Attack Complexity, No Privileges Required, No User Interaction, Unchanged Scope, High Confidentiality Impact, High Integrity Impact, High Availability Impact)
This high CVSS score indicates a critical vulnerability that can be exploited remotely without any required user interaction or privileges. A successful exploit could lead to full compromise of the system.
3. Known Exploit:
While specific exploit code may not be publicly available yet, the nature of the vulnerability suggests the following potential exploit scenarios:
Log File Access: An attacker could gain unauthorized access to log files, potentially revealing:
- Credentials (usernames, passwords, API keys)
- Sensitive application data
- Internal system information
- Configuration settings
Data Breach: Exposure of sensitive data through log files could lead to a significant data breach, compromising user data and potentially violating compliance regulations.
Privilege Escalation: If the logs contain information related to user sessions or system authentication, an attacker could potentially use this information to escalate privileges and gain administrative access.
Denial of Service (DoS): An attacker could potentially manipulate log files to cause a denial of service condition by filling the disk space or corrupting critical application data.
4. Remediation Strategy:
The primary goal of the remediation strategy is to eliminate the insecure log permissions and prevent unauthorized access to sensitive information.
Immediate Action: Upgrade Vasion Print: The most effective remediation is to upgrade to a version of Vasion Print that addresses this vulnerability. According to the CVE description, this means upgrading Virtual Appliance Host to at least version 1.0.735 and Application to at least version 20.0.1330. This is the highest priority action.
Verify Log Permissions: After the upgrade, immediately verify the permissions on all log files generated by Vasion Print. The goal is to restrict access to only authorized users and processes.
Linux/Unix: Use commands like
ls -l
to check the file permissions. The owner and group should be set appropriately (e.g., the Vasion Print service account), and the permissions should be set to restrict access to other users. For example, a common setting is640
(rw-r—–), which allows the owner to read and write, the group to read, and prevents other users from accessing the file. Usechown
andchmod
to adjust permissions.Windows: Use File Explorer or PowerShell to view and modify file permissions. Ensure that only the Vasion Print service account and authorized administrators have access to the log files.
Implement Least Privilege: Ensure that the Vasion Print service account is running with the minimum necessary privileges. This helps limit the potential damage if the account is compromised.
Log Rotation: Implement a robust log rotation policy to prevent log files from growing too large. Regularly archiving and rotating logs will minimize the amount of sensitive data potentially exposed. Consider encrypting archived log files.
Data Masking/Redaction: Consider implementing data masking or redaction techniques to remove sensitive information from log files before they are written. This can include masking credit card numbers, Social Security numbers, and other personally identifiable information (PII). Be aware that overly aggressive masking can hinder troubleshooting.
Centralized Logging: Consider implementing a centralized logging solution that allows you to securely collect, store, and analyze log data. This can improve security monitoring and incident response capabilities. Ensure the centralized logging server is properly secured.
5. Mitigation Strategy (Interim Measures):
If upgrading Vasion Print immediately is not possible, the following mitigation measures should be implemented as soon as possible:
Network Segmentation: Isolate the Vasion Print server on a separate network segment with strict access controls. Limit network traffic to only the necessary ports and protocols.
Web Application Firewall (WAF): If Vasion Print is exposed to the internet, implement a WAF to protect against common web attacks. Configure the WAF to block suspicious traffic and monitor for potential exploits.
Intrusion Detection/Prevention System (IDS/IPS): Deploy an IDS/IPS to monitor network traffic for malicious activity targeting Vasion Print. Configure the IDS/IPS to generate alerts for suspicious events.
Regular Security Audits: Conduct regular security audits to identify potential vulnerabilities and misconfigurations. Include a review of log permissions and access controls.
Monitoring and Alerting: Implement robust monitoring and alerting to detect suspicious activity, such as unauthorized access to log files.
6. Communication:
- Inform Stakeholders: Communicate the vulnerability and the planned remediation/mitigation strategy to all relevant stakeholders, including IT staff, security personnel, and management.
- Provide Updates: Provide regular updates on the progress of the remediation efforts.
7. Post-Remediation Verification:
After implementing the remediation strategy, it is crucial to verify its effectiveness.
- Vulnerability Scanning: Run a vulnerability scan to confirm that CVE-2025-27682 is no longer present.
- Penetration Testing: Consider conducting a penetration test to simulate a real-world attack and validate the security of the system.
- Log Monitoring: Continuously monitor log files for suspicious activity.
8. Disclaimer:
This remediation/mitigation strategy is based on the information available at the time of writing. It is essential to consult the official Vasion Print documentation and security advisories for the most up-to-date information and recommendations. This information should not be considered exhaustive and further investigation is required to ensure complete mitigation.
