Auth bypass in Vasion Print Application
CVE-2025-34230
Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (VA/SaaS deployments) contain a blind server-side request forgery (SSRF) vulnerability reachable via the /var/www/app/console_release/hp/log_off_single_sign_on.php script that can be exploited by an unauthenticated user. When a printer is registered, the software stores the printer’s host name in the variable $printer_vo->str_host_address. The code later builds a URL like 'http://<host‑address>:80/DevMgmt/DiscoveryTree.xml' and sends the request with curl. No validation, whitelist, or private‑network filtering is performed before the request is made. Because the request is blind, an attacker cannot see the data directly, but can still: probe internal services, trigger internal actions, or gather other intelligence. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.
