CVE-2025-27652: Printerlogic Vasion Print SSRF Vulnerability

CVE-2025-27652 Overview

CVE-2025-27652 is a Server-Side Request Forgery (SSRF) vulnerability affecting Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.862 and Application versions before 20.0.2014. This vulnerability, tracked as rfIDEAS V-2023-015, allows attackers to manipulate the server into making unauthorized requests to internal or external resources, potentially exposing sensitive data or enabling further attacks on internal infrastructure.

Critical Impact

This SSRF vulnerability enables unauthenticated remote attackers to leverage the Vasion Print server as a proxy to access internal network resources, potentially bypassing network segmentation and security controls while exposing sensitive internal services.

Affected Products

• Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions before 22.0.862
• Vasion Print Application versions before 20.0.2014
• PrinterLogic Virtual Appliance deployments using vulnerable versions

Technical Details for CVE-2025-27652

Vulnerability Analysis

This Server-Side Request Forgery (SSRF) vulnerability exists within the Vasion Print (formerly PrinterLogic) application stack. SSRF vulnerabilities occur when an application can be induced to make HTTP requests to arbitrary destinations specified by an attacker. In this case, the vulnerability allows an unauthenticated attacker to manipulate the PrinterLogic server into making requests on their behalf.

The vulnerability is classified under CWE-918 (Server-Side Request Forgery), which describes the weakness where a web application fetches a remote resource without sufficiently validating the user-supplied URL. The network-accessible nature of this vulnerability, combined with no required privileges or user interaction, makes it particularly dangerous in enterprise environments where PrinterLogic may have access to internal network resources.

Root Cause

The root cause of this vulnerability lies in insufficient validation of user-controlled input that specifies remote resources to be accessed by the server. The PrinterLogic application fails to properly sanitize or restrict URLs that are passed to server-side request functions, allowing attackers to specify arbitrary destinations including internal network addresses, cloud metadata services, and other sensitive endpoints.

Attack Vector

An attacker can exploit this vulnerability by sending specially crafted requests to the vulnerable PrinterLogic server that contain malicious URLs. The server then makes requests to these attacker-specified destinations, potentially:

• Accessing internal services that are not directly accessible from the internet
• Retrieving cloud instance metadata containing credentials or configuration data
• Scanning internal network infrastructure to identify additional targets
• Bypassing firewall rules and network access controls
• Exfiltrating data from internal systems through the trusted server

Since this vulnerability requires no authentication and no user interaction, an attacker with network access to the PrinterLogic server can immediately begin exploitation. The vulnerability mechanism involves the server parsing user-supplied URLs and making outbound requests without adequate validation of the destination.

Detection Methods for CVE-2025-27652

Indicators of Compromise

• Unusual outbound HTTP/HTTPS requests from the PrinterLogic server to internal IP ranges (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
• Requests to cloud metadata endpoints such as 169.254.169.254 originating from the PrinterLogic application
• Log entries showing requests to unexpected internal hostnames or services from the PrinterLogic server
• Network traffic patterns indicating port scanning or service enumeration from the PrinterLogic host

Detection Strategies

• Implement network monitoring to detect anomalous outbound connections from PrinterLogic servers to internal network segments
• Configure web application firewalls (WAF) to inspect and block requests containing internal IP addresses or suspicious URL patterns
• Enable verbose logging on the PrinterLogic application and monitor for unusual URL processing activities
• Deploy intrusion detection systems (IDS) with rules specifically targeting SSRF attack patterns

Monitoring Recommendations

• Monitor DNS queries from the PrinterLogic server for resolution of internal hostnames or unusual external domains
• Track outbound connection attempts from the PrinterLogic server to non-standard ports or internal services
• Review application logs for error messages that may indicate failed SSRF attempts
• Implement egress filtering and log all outbound connections from the PrinterLogic infrastructure

How to Mitigate CVE-2025-27652

Immediate Actions Required

• Upgrade Vasion Print Virtual Appliance Host to version 22.0.862 or later immediately
• Upgrade Vasion Print Application to version 20.0.2014 or later
• Review network segmentation to limit the PrinterLogic server's access to internal resources
• Implement egress filtering to restrict outbound connections from the PrinterLogic server to only necessary destinations

Patch Information

Vasion (formerly PrinterLogic) has released patches addressing this vulnerability in Virtual Appliance Host version 22.0.862 and Application version 20.0.2014. Organizations should consult the PrinterLogic Security Bulletins for detailed patching instructions and additional security guidance.

Workarounds

• Place the PrinterLogic server behind a web application firewall (WAF) configured to block SSRF attack patterns
• Implement strict network segmentation to limit the server's access to internal resources
• Configure firewall rules to restrict outbound connections from the PrinterLogic server to only required external services
• Enable allowlist-based URL validation if configurable within the application
• Consider temporarily restricting network access to the PrinterLogic server to trusted internal users only until patching can be completed

# Example firewall rules to restrict PrinterLogic server egress (adjust for your environment)
# Block access to internal network ranges from PrinterLogic server
iptables -A OUTPUT -s <printerlogic_server_ip> -d 10.0.0.0/8 -j DROP
iptables -A OUTPUT -s <printerlogic_server_ip> -d 172.16.0.0/12 -j DROP
iptables -A OUTPUT -s <printerlogic_server_ip> -d 192.168.0.0/16 -j DROP
# Block access to cloud metadata service
iptables -A OUTPUT -s <printerlogic_server_ip> -d 169.254.169.254 -j DROP
