CVE-2025-27655 is a critical Server-Side Request Forgery (SSRF) vulnerability identified in Vasion Print (formerly PrinterLogic) software, specifically affecting versions before Virtual Appliance Host 22.0.862 Application 20.0.2014. SSRF vulnerabilities occur when an attacker can manipulate a vulnerable server to send crafted requests to internal or external systems that the attacker cannot directly access. In this case, the vulnerability allows an unauthenticated attacker to exploit the server to perform arbitrary HTTP requests, potentially accessing internal resources, sensitive data, or triggering further attacks such as remote code execution or lateral movement within a network. The vulnerability is classified under CWE-918, which covers SSRF issues. The CVSS v3.1 base score of 9.8 indicates a critical severity level, with attack vector being network-based (AV:N), no privileges required (PR:N), no user interaction needed (UI:N), and impacts on confidentiality, integrity, and availability all rated high (C:H/I:H/A:H). This means exploitation can lead to complete compromise of the affected system and potentially the broader network environment. No patches or exploit code are currently publicly available, but the vulnerability is officially published and should be addressed promptly. Given the nature of print management software, which often integrates deeply into enterprise IT environments, exploitation could allow attackers to pivot to other critical systems or exfiltrate sensitive information. The lack of authentication requirement and ease of exploitation make this vulnerability particularly dangerous.

For European organizations, the impact of CVE-2025-27655 can be severe. Vasion Print is used in many enterprise environments to manage print infrastructure, often integrated with Active Directory and other internal services. Exploitation could allow attackers to bypass network segmentation by leveraging the print server as a proxy to access internal resources, leading to data breaches, disruption of printing services, and potential ransomware deployment. Confidentiality is at risk as attackers may access sensitive documents or internal APIs. Integrity and availability are also threatened since attackers could alter print jobs, disrupt printing services, or use the compromised server as a foothold for further attacks. Critical sectors such as government, finance, healthcare, and manufacturing in Europe that rely on secure and reliable print services could face operational disruptions and data loss. The vulnerability’s network-level exploitability without authentication increases the risk of widespread attacks, especially in environments with exposed or poorly segmented print servers.

1. Immediately upgrade Vasion Print to Virtual Appliance Host 22.0.862 Application 20.0.2014 or later, where the vulnerability is addressed. 2. If patching is not immediately possible, restrict network access to the print server by implementing firewall rules that limit inbound connections to trusted management networks only. 3. Employ network segmentation to isolate print servers from sensitive internal systems and the internet. 4. Monitor network traffic for unusual outbound requests originating from print servers, which may indicate SSRF exploitation attempts. 5. Conduct regular vulnerability scans and penetration tests focusing on print infrastructure to detect potential exploitation. 6. Review and harden print server configurations, disabling unnecessary services and interfaces that could be abused. 7. Implement strict access controls and logging to detect unauthorized access attempts. 8. Educate IT staff on the risks associated with SSRF and the importance of timely patching and network hygiene.
