CVE-2025-34230Public exploitNetwork attack vector

Unauthenticated internal service probing via printer hostname

Published Sep 29, 2025 · Updated Sep 29, 2025

Blind SSRF in Vasion Print Application before 25.1.1413 and Virtual Appliance Host before 25.1.102 allows remote attackers to probe internal services. The log_off_single_sign_on.php script passes an attacker-controlled printer hostname to file_get_contents and cURL without URL or private-network validation. The endpoint requires no authentication, but the blind responses expose no data directly; induced requests can discover services or trigger reachable internal actions.
