CVE-2025-34225 is a server-side request forgery (SSRF) vulnerability affecting Vasion Print Virtual Appliance Host (formerly PrinterLogic) prior to version 25.1.102 and its Application prior to version 25.1.1413 in VA/SaaS deployments. The vulnerability stems from the 'console_release' directory being exposed to the internet without any authentication controls. Within this directory, numerous PHP scripts construct URLs based on user-supplied input and then execute HTTP requests using functions like curl_exec() or file_get_contents(). Although some scripts attempt to filter inputs using PHP's filter_var function, these checks are incomplete and insufficient to prevent SSRF attacks. Because the endpoint is unauthenticated, any remote attacker can supply arbitrary hostnames, causing the server to issue HTTP requests to internal network resources that would otherwise be inaccessible externally. This can facilitate internal network reconnaissance, allowing attackers to map internal infrastructure, identify sensitive services, or pivot to other internal systems. Additionally, attackers might leverage this to exfiltrate data or launch further attacks within the internal network. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function) and CWE-918 (Server-Side Request Forgery). The CVSS 4.0 base score is 8.8, indicating a high-severity issue with network attack vector, no required privileges or user interaction, and high impact on confidentiality. Although a patch exists, the exact timing of its release is unclear, and no public exploits have been reported to date. Organizations using affected versions should urgently verify their deployment status and apply updates or mitigations.

For European organizations, this vulnerability poses a significant risk, especially for those using Vasion Print Virtual Appliance Host in VA or SaaS deployments exposed to the internet. The unauthenticated SSRF can allow attackers to bypass perimeter defenses and access internal network resources, potentially leading to disclosure of sensitive internal services, credentials, or configuration data. This can facilitate lateral movement within corporate networks, increasing the risk of broader compromise. Confidentiality is most impacted, but integrity and availability could also be affected if attackers leverage internal services for further exploitation or denial-of-service attacks. Organizations in sectors with sensitive data or critical infrastructure—such as government, finance, healthcare, and manufacturing—are particularly at risk. The vulnerability's ease of exploitation and lack of required authentication amplify its threat. Failure to remediate could lead to data breaches, operational disruptions, and regulatory non-compliance under GDPR and other European data protection laws.

1. Immediately identify and inventory all Vasion Print Virtual Appliance Host and Application deployments, verifying versions to determine exposure. 2. Apply the latest available patches from Vasion to update to version 25.1.102 or later for the Virtual Appliance Host and 25.1.1413 or later for the Application. 3. If patching is not immediately possible, restrict external network access to the 'console_release' directory using firewall rules or network segmentation to prevent unauthenticated internet access. 4. Implement web application firewalls (WAFs) with custom rules to detect and block SSRF attack patterns targeting these endpoints. 5. Conduct internal network monitoring and logging to detect unusual outbound HTTP requests originating from the appliance, which may indicate exploitation attempts. 6. Review and harden PHP scripts or configurations related to URL handling and input validation to ensure robust filtering beyond filter_var, including whitelisting allowed hosts or IP ranges. 7. Educate IT and security teams about this vulnerability and incorporate it into incident response plans. 8. Regularly audit and monitor SaaS/VA deployments for exposure and anomalous activity. 9. Coordinate with Vasion support for any additional recommended mitigations or updates.
