CVE-2025-34231 is a critical server-side request forgery (SSRF) vulnerability affecting Vasion Print Virtual Appliance Host and Application deployments prior to versions 25.1.102 and 25.1.1413 respectively. The vulnerability exists in the '/var/www/app/console_release/hp/badgeSetup.php' script, which is accessible from the internet without any authentication. This script accepts user-controlled parameters to build URLs that are then fetched either via a custom processCurl() function or PHP’s file_get_contents() function. Crucially, there is no whitelist, scheme restriction, IP-range validation, or outbound network filtering applied to these URLs. As a result, an unauthenticated attacker can coerce the server into making arbitrary HTTP requests to internal or external resources. This SSRF flaw enables attackers to perform internal network reconnaissance, potentially access sensitive internal services, leak credentials, pivot to other systems, and exfiltrate data. The vulnerability is categorized under CWE-306 (Missing Authentication for Critical Function) and CWE-918 (Server-Side Request Forgery). The CVSS 4.0 vector indicates no authentication or user interaction is required, with network attack vector and high confidentiality impact. Although a patch exists, the exact release date is unclear, and no public exploits have been reported yet. The vulnerability affects all versions prior to the patch, making all unpatched Vasion Print Virtual Appliance Hosts vulnerable.

For European organizations, this vulnerability poses a significant risk due to the potential for attackers to bypass perimeter defenses and access internal network resources via the vulnerable Vasion Print Virtual Appliance Host. The ability to perform internal reconnaissance can reveal sensitive infrastructure details, while credential leakage and pivoting can lead to broader network compromise. Organizations relying on Vasion Print for print management in critical sectors such as government, finance, healthcare, and manufacturing could face data breaches, operational disruption, and compliance violations under GDPR. The unauthenticated nature of the vulnerability increases the risk of exploitation by external threat actors, including cybercriminals and state-sponsored groups. Additionally, the lack of outbound filtering on the vulnerable component could facilitate data exfiltration or command and control communications. Given the widespread use of print management solutions in enterprise environments, the scope of affected systems could be extensive, amplifying the impact across multiple European countries.

European organizations should immediately verify their Vasion Print Virtual Appliance Host and Application versions and upgrade to versions 25.1.102 and 25.1.1413 or later where the vulnerability is patched. If immediate patching is not possible, implement network-level controls to restrict outbound HTTP/HTTPS requests from the appliance to only trusted destinations, effectively limiting SSRF exploitation. Employ strict egress filtering and firewall rules to prevent the appliance from accessing internal management interfaces or sensitive internal services. Conduct thorough network segmentation to isolate print management infrastructure from critical systems and sensitive data stores. Monitor network traffic for unusual outbound requests originating from the appliance, and enable logging and alerting on suspicious activities. Review and harden appliance configuration to disable unnecessary services or scripts exposed to the internet. Finally, engage in threat hunting and incident response readiness to detect any signs of exploitation attempts.
