CVE-2025-27662 Overview
CVE-2025-27662 is a critical information disclosure vulnerability affecting Vasion Print (formerly PrinterLogic) Virtual Appliance Host before version 22.0.843 and Application before version 20.0.1923. The vulnerability involves the insecure transmission of passwords within URL parameters, which can lead to credential exposure through browser history, server logs, referrer headers, and network traffic analysis.
Critical Impact
This vulnerability allows attackers to potentially capture authentication credentials transmitted in URLs, leading to unauthorized access to print management systems and potential lateral movement within enterprise environments.
Affected Products
- Vasion Print (PrinterLogic) Virtual Appliance Host versions before 22.0.843
- Vasion Print (PrinterLogic) Application versions before 20.0.1923
- PrinterLogic Virtual Appliance (all versions prior to patched releases)

Technical Details for CVE-2025-27662
Vulnerability Analysis
This vulnerability is classified under CWE-256 (Plaintext Storage of a Password), though the specific attack vector involves passwords being transmitted within URL parameters. When credentials are included in URLs, they are susceptible to exposure through multiple channels including browser history, proxy logs, server access logs, HTTP referrer headers, and shoulder surfing attacks.
The vulnerability is network-accessible and requires no authentication or user interaction to exploit, making it particularly dangerous in enterprise environments where PrinterLogic/Vasion Print systems manage printer infrastructure across the organization.
Root Cause
The root cause of this vulnerability stems from improper handling of sensitive authentication data within the application. Instead of transmitting credentials through secure methods such as POST request bodies over HTTPS or properly encrypted authentication headers, the application includes password data directly in URL query parameters. This design flaw violates fundamental security principles for credential handling and exposes authentication data to numerous attack vectors.
Attack Vector
The attack vector for this vulnerability is network-based with low complexity. An attacker can intercept credentials through several methods:
- Network Traffic Analysis: Even over HTTPS, URLs may be visible in proxy logs or through TLS inspection
- Browser History Mining: Credentials persist in browser history on client systems
- Server Log Analysis: Web server access logs typically record full URLs including query parameters
- Referrer Header Leakage: When users navigate to external sites, the credential-containing URL may be transmitted in HTTP Referer headers
- Shoulder Surfing: URLs are visible in browser address bars
Since no code examples were provided, the vulnerability mechanism can be understood as credential data being appended to URLs in the format: https://vasionprint.example.com/login?password=secretvalue rather than being transmitted securely in POST request bodies.
Detection Methods for CVE-2025-27662
Indicators of Compromise
- Unusual access patterns to PrinterLogic/Vasion Print administrative interfaces from unauthorized IP addresses
- Authentication attempts using credentials harvested from log files or browser history
- Evidence of log file access or exfiltration from web servers hosting the application
- Suspicious network traffic analysis tools or proxy configurations targeting the print management system
Detection Strategies
- Review web server access logs for URLs containing authentication-related parameters such as password, pwd, pass, or credential
- Implement network monitoring to detect potential credential harvesting attempts targeting the Vasion Print application
- Deploy endpoint detection to identify unauthorized access to browser history files on systems that access PrinterLogic
- Monitor for unauthorized administrative actions within the PrinterLogic/Vasion Print management console
Monitoring Recommendations
- Enable detailed logging on the Vasion Print Virtual Appliance and forward logs to a SIEM solution
- Implement user behavior analytics to detect anomalous authentication patterns
- Configure alerts for administrative access from unexpected geographic locations or IP ranges
- Regularly audit user accounts and permissions within the print management system
How to Mitigate CVE-2025-27662
Immediate Actions Required
- Upgrade Vasion Print Virtual Appliance Host to version 22.0.843 or later
- Upgrade Vasion Print Application to version 20.0.1923 or later
- Rotate all user credentials, especially administrative accounts, after applying patches
- Review web server and proxy logs for potential credential exposure and notify affected users
- Enable multi-factor authentication if available to add an additional layer of security
Patch Information
Vasion (formerly PrinterLogic) has released security updates addressing this vulnerability. Organizations should consult the PrinterLogic Security Bulletins for detailed patch information and upgrade instructions. The patched versions are:
- Virtual Appliance Host: 22.0.843 or later
- Application: 20.0.1923 or later
Workarounds
- If immediate patching is not possible, restrict network access to the Vasion Print management interface to trusted IP ranges only
- Place the Vasion Print Virtual Appliance behind a reverse proxy that can sanitize or block requests with credentials in URL parameters
- Implement network segmentation to limit exposure of the print management system
- Enforce the use of VPN connections for all administrative access to the system
- Consider disabling external access to the management interface until patches can be applied
# Example: Restrict access to Vasion Print management interface via firewall
# Allow only trusted admin network
iptables -A INPUT -p tcp --dport 443 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
# Alternatively, configure web server to require client certificates
# Apache example - add to virtual host configuration
# SSLVerifyClient require
# SSLVerifyDepth 1
# SSLCACertificateFile /path/to/ca-certificate.pem
